-## GTK CI infrastructure
-
-GTK uses different CI images depending on platform and jobs.
-
-The CI images are Docker containers, generated either using `docker` or
-`podman`, and pushed to the GitLab [container registry][registry].
-
-Each Docker image has a tag composed of two parts:
-
- - `${image}`: the base image for a given platform, like "fedora" or
-   "debian-stable"
- - `${number}`: an incremental version number, or `latest`
-
-See the [container registry][registry] for the available images for each
-branch, as well as their available versions.
-
-### Checklist for Updating a CI image
-
- - [ ] Update the `${image}.Dockerfile` file with the dependencies
- - [ ] Run `./run-docker.sh build --base ${image} --base-version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --base-version ${number}`
-   once the Docker image is built; you may need to log in by using
-   `docker login` or `podman login`
- - [ ] Update the `image` keys in the `.gitlab-ci.yml` file with the new
-   image tag
- - [ ] Open a merge request with your changes and let it run
-
-### Checklist for Adding a new CI image
-
- - [ ] Write a new `${image}.Dockerfile` with the instructions to set up
-   a build environment
- - [ ] Add the `pip3 install meson` incantation
- - [ ] Run `./run-docker.sh build --base ${image} --base-version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --base-version ${number}`
- - [ ] Add the new job to `.gitlab-ci.yml` referencing the image
- - [ ] Open a merge request with your changes and let it run
-
-### Checklist for Adding a new dependency to a CI image
-
-Our images are layered, and the base (called fedora-base) contains
-all the rpm payload. Therefore, adding a new dependency is a 2-step
-process:
-
- 1. [ ] Build and upload fedora-base:$version+1
- 1. [ ] Build and upload fedora:$version+1 based on fedora-base:version+1

-# Contribution guidelines
-
-Thank you for considering contributing to the GTK project!
-
-These guidelines are meant for new contributors, regardless of their level
-of proficiency; following them allows the maintainers of the GTK project to
-more effectively evaluate your contribution, and provide prompt feedback to
-you. Additionally, by following these guidelines you clearly communicate
-that you respect the time and effort that the people developing GTK put into
-managing the project.
-
-GTK is a complex free software GUI toolkit, and it would not exist without
-contributions from the free and open source software community. There are
-many things that we value:
-
- - bug reporting and fixing
- - documentation and examples
- - tests
- - new features
-
-Please, do not use the issue tracker for support questions. If you have
-questions on how to use GTK effectively, you can use:
-
- - the `#gtk` IRC channel on irc.gnome.org
- - the [gtk tag on the GNOME Discourse instance](https://discourse.gnome.org/tag/gtk)
-
-You can also look at the GTK tag on [Stack
-Overflow](https://stackoverflow.com/questions/tagged/gtk).
-
-The issue tracker is meant to be used for actionable issues only.
-
-## How to report bugs
-
-### Security issues
-
-You should not open a new issue for security related questions.
-
-When in doubt, send an email to the [security](mailto:security@gnome.org)

-### Bug reports
-
-If you're reporting a bug make sure to list:
-
- 0. which version of GTK are you using?
- 0. which operating system are you using?
- 0. the necessary steps to reproduce the issue
- 0. the expected outcome
- 0. a description of the behavior; screenshots are also welcome
- 0. a small, self-contained example exhibiting the behavior; if this
-    is not available, try reproducing the issue using the GTK examples
-    or interactive tests
-
-If the issue includes a crash, you should also include:
-
- 0. the eventual warnings printed on the terminal
- 0. a backtrace, obtained with tools such as GDB or LLDB
-
-It is fine to include screenshots of screen recordings to demonstrate
-an issue that is best to understand visually, but please don't just
-dump screen recordings without further details into issues. It is
-essential that the problem is described in enough detail to reproduce
-it without watching a video.
-
-For small issues, such as:
-
- - spelling/grammar fixes in the documentation
- - typo correction
- - comment clean ups
- - changes to metadata files (CI, `.gitignore`)
- - build system changes
- - source tree clean ups and reorganizations
-
-You should directly open a merge request instead of filing a new issue.
-
-### Features and enhancements
-
-Feature discussion can be open ended and require high bandwidth channels; if
-you are proposing a new feature on the issue tracker, make sure to make
-an actionable proposal, and list:
-
- 0. what you're trying to achieve
- 0. prior art, in other toolkits or applications
- 0. design and theming changes
-
-If you're proposing the integration of new features it helps to have
-multiple applications using shared or similar code, especially if they have
-iterated over it various times.
-
-Each feature should also come fully documented, and with tests.
-
-## Your first contribution
-
-### Prerequisites
-
-If you want to contribute to the GTK project, you will need to have the
-development tools appropriate for your operating system, including:
-
- - Python 3.x
- - Meson
- - Ninja
- - Gettext (19.7 or newer)
- - a [C99 compatible compiler](https://wiki.gnome.org/Projects/GLib/CompilerRequirements)
-
-Up-to-date instructions about developing GNOME applications and libraries
-can be found on [the GNOME Developer Center](https://developer.gnome.org).
-
-The GTK project uses GitLab for code hosting and for tracking issues. More
-information about using GitLab can be found [on the GNOME
-wiki](https://wiki.gnome.org/GitLab).
-
-### Dependencies
-
-In order to get GTK from Git installed on your system, you need to have the
-required versions of all the software dependencies required by GTK; typically,
-this means a recent version of GLib, Cairo, Pango, and ATK, as well as the
-platform-specific dependencies for the windowing system you are using (Wayland,
-X11, Windows, or macOS).
-
-The core dependencies for GTK are:
-
- - [GLib, GObject, and GIO](https://gitlab.gnome.org/GNOME/glib)
- - [Cairo](http://cairographics.org)
- - [Pango](https://gitlab.gnome.org/GNOME/pango)
- - [GdkPixbuf](https://gitlab.gnome.org/GNOME/gdk-pixbuf)
- - [Epoxy](https://github.com/anholt/libepoxy)
- - [ATK](https://gitlab.gnome.org/GNOME/atk)
- - [Graphene](https://github.com/ebassi/graphene)
-
-GTK will attempt to download and build some of these dependencies if it
-cannot find them on your system.
-
-Additionally, you may want to look at projects that create a development
-environment for you, like [jhbuild](https://wiki.gnome.org/HowDoI/Jhbuild)
-and [gvsbuild](https://github.com/wingtk/gvsbuild).
-
-### Getting started
-
-You should start by forking the GTK repository from the GitLab web UI, and
-cloning from your fork:
-
-```sh
-$ git clone https://gitlab.gnome.org/yourusername/gtk.git
-$ cd gtk
-```
-
-**Note**: if you plan to push changes to back to the main repository and
-have a GNOME account, you can skip the fork, and use the following instead:
-
-```sh
-$ git clone git@gitlab.gnome.org:GNOME/gtk.git
-$ cd gtk
-```
-
-To compile the Git version of GTK on your system, you will need to
-configure your build using Meson:
-
-```sh
-$ meson _builddir .
-$ cd _builddir
-$ ninja
-```
-
-Typically, you should work on your own branch:
-
-```sh
-$ git checkout -b your-branch
-```
-
-Once you've finished working on the bug fix or feature, push the branch
-to the Git repository and open a new merge request, to let the GTK
-maintainers review your contribution.
-
-### Code reviews
-
-Each contribution is reviewed by the core developers of the GTK project.
-
-The [CODEOWNERS](./docs/CODEOWNERS) document contains the list of core
-contributors to GTK and the areas for which they are responsible; you
-should ensure to receive their review and signoff on your changes.
-
-### Commit messages
-
-The expected format for git commit messages is as follows:
-
-```plain
-Short explanation of the commit
-
-Longer explanation explaining exactly what's changed, whether any
-external or private interfaces changed, what bugs were fixed (with bug
-tracker reference if applicable) and so forth. Be concise but not too
-brief.
-
-Closes #1234
-```
-
- - Always add a brief description of the commit to the _first_ line of
- the commit and terminate by two newlines (it will work without the
- second newline, but that is not nice for the interfaces).
-
- - First line (the brief description) must only be one sentence and
- should start with a capital letter unless it starts with a lowercase
- symbol or identifier. Don't use a trailing period either. Don't exceed
- 72 characters.
-
- - The main description (the body) is normal prose and should use normal
- punctuation and capital letters where appropriate. Consider the commit
- message as an email sent to the developers (or yourself, six months
- down the line) detailing **why** you changed something. There's no need
- to specify the **how**: the changes can be inlined.
-
- - When committing code on behalf of others use the `--author` option, e.g.
- `git commit -a --author "Joe Coder <joe@coder.org>"` and `--signoff`.
-
- - If your commit is addressing an issue, use the
- [GitLab syntax](https://docs.gitlab.com/ce/user/project/issues/automatic_issue_closing.html)
- to automatically close the issue when merging the commit with the upstream
- repository:
-
-```plain
-Closes #1234
-Fixes #1234
-Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1234
-```
-
- - If you have a merge request with multiple commits and none of them
- completely fixes an issue, you should add a reference to the issue in
- the commit message, e.g. `Bug: #1234`, and use the automatic issue
- closing syntax in the description of the merge request.
-
-### Commit access to the GTK repository
-
-GTK is part of the GNOME infrastructure. At the current time, any
-person with write access to the GNOME repository can merge changes to
-GTK. This is a good thing, in that it encourages many people to work
-on GTK, and progress can be made quickly. However, GTK is a fairly
-large and complicated project on which many other things depend, so to
-avoid unnecessary breakage, and to take advantage of the knowledge
-about GTK that has been built up over the years, we'd like to ask
-people committing to GTK to follow a few rules:
-
-0. Ask first. If your changes are major, or could possibly break existing
-   code, you should always ask. If your change is minor and you've been
-   working on GTK for a while it probably isn't necessary to ask. But when
-   in doubt, ask. Even if your change is correct, somebody may know a
-   better way to do things. If you are making changes to GTK, you should
-   be subscribed to the [gtk-devel](https://mail.gnome.org/mailman/listinfo/gtk-devel-list)
-   mailing list; this is a good place to ask about intended changes.
-   The `#gtk` IRC channel on irc.gnome.org is also a good place to find GTK
-   developers to discuss changes, but if you live outside of the EU/US time
-   zones, an email to the gtk-devel mailing list is the most certain and
-   preferred method.
-
-0. Ask _first_.
-
-0. Always write a meaningful commit message. Changes without a sufficient
-   commit message will be reverted.
-
-0. Never push to the `master` branch, or any stable branches, directly; you
-   should always go through a merge request, to ensure that the code is
-   tested on the CI infrastructure at the very least. A merge request is
-   also the proper place to get a comprehensive code review from the core
-   developers of GTK.
-
-If you have been contributing to GTK for a while and you don't have commit
-access to the repository, you may ask to obtain it following the [GNOME account
-process](https://wiki.gnome.org/AccountsTeam/NewAccounts).

-                       Version 2, June 1991
-
- Copyright (C) 1991 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the library GPL.  It is
- numbered 2 because it goes with version 2 of the ordinary GPL.]
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Library General Public License, applies to some
-specially designated Free Software Foundation software, and to any
-other libraries whose authors decide to use it.  You can use it for
-your libraries, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if
-you distribute copies of the library, or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  Our method of protecting your rights has two steps: (1) copyright
-the library, and (2) offer you this license which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library.  If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original
-version, so that any problems introduced by others will not reflect on
-the original authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software.  To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
-  Most GNU software, including some libraries, is covered by the ordinary
-GNU General Public License, which was designed for utility programs.  This
-license, the GNU Library General Public License, applies to certain
-designated libraries.  This license is quite different from the ordinary
-one; be sure to read it in full, and don't assume that anything in it is
-the same as in the ordinary license.
-
-  The reason we have a separate public license for some libraries is that
-they blur the distinction we usually make between modifying or adding to a
-program and simply using it.  Linking a program with a library, without
-changing the library, is in some sense simply using the library, and is
-analogous to running a utility program or application program.  However, in
-a textual and legal sense, the linked executable is a combined work, a
-derivative of the original library, and the ordinary General Public License
-treats it as such.
-
-  Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries.  We
-concluded that weaker conditions might promote sharing better.
-
-  However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves.  This Library General Public License is intended to
-permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them.  (We have not seen how to achieve
-this as regards changes in header files, but we have achieved it as regards
-changes in the actual functions of the Library.)  The hope is that this
-will lead to faster development of free libraries.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, while the latter only
-works together with the library.
-
-  Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.
-
-                  GNU LIBRARY GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library which
-contains a notice placed by the copyright holder or other authorized
-party saying it may be distributed under the terms of this Library
-General Public License (also called "this License").  Each licensee is
-addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also compile or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    c) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    d) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the source code distributed need not include anything that is normally
-distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-

-
-Overview of Changes in GTK+ 1.3.1:
-
-* GTK+ now uses the Pango library for text manipulation. All
-  strings in GTK+ now are in Unicode, languages written
-  from right-to-left, and complex-text languages are now supported.
-* The gdk-pixbuf library for image loading and manipulation is 
-  has been integrated with GTK+.
-* The GTK+ object system has mostly been moved to GLib, separating
-  it from the GUI code. Many significant enhancements have been
-  made as part of this.
-* A new text widget is now included. This started as a port
-  of the Tk text widget, and includes such features of the Tk
-  text widget as tags, marks, and unicode text support. It
-  has been enhanced to support model-view operation and the
-  full power of Pango.
-* The GDK library has been extensively revised to support multiple
-  windowing systems. The only fully functional backend in 1.3.1
-  is the X11 backend, however, ports to Win32, Linux-framebuffer,
-  Nano-X, BeOS, and MacOS exist in various states of completion,
-  and at least some of these will be finished and integrated in 
-  before the final GTK+-2.0 release.
-* 32-bit coordinates are now supported throughout GDK and GTK+
-  (they are emulated where not supported by the windowing system.)
-* Many minor bug fixes and enhancements. Incompatible changes
-  are documented in docs/Changes-2.0.txt
-
-Overview of Changes in GTK+ 1.2.8:
-
-* GNU Make 3.79 bug workaround

-  HScale, VScale, Pixmap, Viewport, OptionMenu, Entry and Notebook.
-* Upgrade to libtool 1.3.4.
-
-Overview of Changes in GTK+ 1.2.6:
-
-* container queue_resize fixes
-* gtk[vh]scale: minor fixups

-  broken libs
-* More consistent naming of gtkrc files
-* Added language support: ro, uk
-
-Overview of Changes in GTK+ 1.2.5:
-
-* more GtkCTree and GtkWindow bug fixes.
-* more redraw/resize queue fixes, better expose event
-  discarding code.
-* more miscellaneous bugs fixed
-* new configure.in option --disable-rebuilds to completely disable
-  rebuilds of autogenerated sources.
-* check for 5.002 now, to avoid failing autogeneration build rules due
-  to old perl versions.
-* fonts (and fontsets) are cached now.
-* more autogeneration make rules and dependency fixups, we should be
-  save with autogeneration up to make -j12 now ;)
-* new window position GTK_WIN_POS_CENTER_ALWAYS, which will recenter the
-  GtkWindow on every size change.
-* major rework of window manager hints handling code, fixed a bunch of
-  races with the new resizing code.
-* the new wm hints and resizing code is absolutely perfect and bug free now,
-  it only lacks testing ;)
-* fixed up various rc style memory problems.
-* gtk_widget_modify_style() now properly changes the style of realized widgets
-  and references the style passed into it. if people worked around this bug,
-  this will introduce a slight memory leak in their code.
-  The code should typically look like:
-            GtkRcStyle *rc_style = gtk_rc_style_new ();
-            [...]
-            gtk_widget_modify_style (widget, rc_style);
-            gtk_rc_style_unref (rc_style);
-* fix problems with positioning menus offscreen.
-* GtkText fixes for some crashes and drawing errors.
-* Better handling for unexpected window destroys in GDK and GTK+.
-  This should make it possible to use a GtkPlug and catch the
-  case where its parent socket is randomly killed.
-* FAQ updates.
-* FileSelection i18n patches, RadioButton fixups.
-* many translation improvements.
-* miscellaneous other bugs fixed.
-

-* Fixed mapping for GdkInputCondition<->GIOCondition, this should fix
-  problems where closed pipes were no longer signaling GDK_INPUT_READ on
-  systems with a native poll().
-* Some cleanups to GtkLabel's memory allocation code (shouldn't leak memory
-  anymore).
-* We don't attempt to lookup xpm color "None" anymore, this should prevent
-  eXodus (commercial X windows server) from popping up a color dialog every
-  time a transparent pixmap is created.
-* Fixed bug where Gtk timeout/idle handlers would execute without the global
-  Gdk lock being held.
-* Other minor bug fixes.
-
-Overview of Changes in GTK+ 1.2.1:
-
-* Many Bug fixes have been applied to the menu and accelerator code.

-  like accelerator propagation between different windows with the same
-  menu hierarchy and for centralized parsing and saving of accelerators.
-* GtkCList/GtkCTree buttons should always display correctly now.
-* Miscellaneous other bug fixes.
-

-  widget->requisition is always what the widget requested,
-  unmodified by the usize. See Changes-1.2.txt for details.
-  This correct various bugs with gtk_widget_set_usize().
-* Fixes for XIM on X11R5 systems
-* Don't allow cut-and-paste of text in password-style entries

-  for NO_WINDOW children, adjust allocations of children as 
-  scrolled so queued draws work, and a resize is queued instead
-  of allocating directly in a put() or move()
-
-What is new in GTK+ 1.1.13:
-
-* Dnd and selection bug fixes and memory purification.
-* Widget sensitivity fixups.
-* Tooltips windows are now named "gtk-tooltips" so rc file rules

-  expose event generation.
-* Gdk event queue fixups, this solves the double-click problems people were

+project files for ATK and AT-SPI2.
 
-Or [online](https://developer.gnome.org/gtk4/stable/gtk-building.html)
+The [`gtk3`](./gtk3) directory contains the introspection data and gi-docgen
+project files for GTK3 and GDK3.
 
-How to report bugs
+The [`subprojects`](./subprojects) directory contains a Meson subproject for
+gi-docgen.
+
+How does this work
 ------------------
 
-Bugs should be reported on the [issues page](https://gitlab.gnome.org/GNOME/gtk/issues/new).
+The CI pipeline for the main development branch of GTK builds the API
+references for the following projects:
 
-In the bug report please include:
+ - gtk
+ - pango
+ - gdk-pixbuf
 
-* Information about your system. For instance:
+Similarly, the CI pipeline for the main development branch of GLib builds
+the API references for the following projects:
 
-   - which version of GTK you are using
-   - what operating system and version
-   - for Linux, which distribution
-   - if you built GTK, the list of options used to configure the build
+ - glib
+ - glib-unix
+ - glib-win32
+ - gmodule
+ - gobject
+ - gio
+ - gio-unix
+ - gio-win32
+ - girepository
 
-  And anything else you think is relevant.
+The generated documentation is stored as an artifact inside GitLab.
+Additionally, the CI pipeline will use a pipeline trigger for the
+`docs-gtk-org` branch (the branch that contains the `README` file you are
+currently reading).
 
-* How to reproduce the bug.
+The CI pipeline for the `docs-gtk-org` branch will:
 
-  If you can reproduce it with one of the demo applications that are
-  built in the demos/ subdirectory, on one of the test programs that
-  are built in the tests/ subdirectory, that will be most convenient.
-  Otherwise, please include a short test program that exhibits the
-  behavior. As a last resort, you can also provide a pointer to a
-  larger piece of software that can be downloaded.
+ - download the build artifacts
+ - extract the various API references
+ - run gi-docgen on the introspection data of the following projects:
+   - atk
+   - gtk3
+ - publish the static landing page
+ - publish all the API references
 
-* If the bug was a crash, the exact text that was printed out
-  when the crash occurred.
+Notes
+-----
 
-* Further information such as stack traces may be useful, but
-  is not necessary.
+The token for the pipeline trigger is stored in the `PAGES_TRIGGER_TOKEN`
+environment variable, which is exposed to the CI pipelines of the GTK
+project.

-/* Constraints/Simple Constraints
- * #Keywords: GtkLayoutManager
- *
- * GtkConstraintLayout provides a layout manager that uses relations
- * between widgets (also known as “constraints”) to compute the position
- * and size of each child.
- *
- * In addition to child widgets, the constraints can involve spacer
- * objects (also known as “guides”). This example has a guide between
- * the two buttons in the top row.
- *
- * Try resizing the window to see how the constraints react to update
- * the layout.
