+## For applications developers
 
+Python [AppImages][APPIMAGE] are built using the `python_appimage` Python
+package. You can get it from [GitHub][GITHUB] or [PyPI][PYPI]. Examples of usage
+can be found by browsing GitHub [workflows][WORKFLOWS].
+
+The `python_appimage` package also allows to build basic Python apps from an
+existing Python AppImage and a recipe folder. The recipe folder contains the
+app metadata, a Python requirements file and an entry point script. Examples of
+recipes can be found on GitHub in the [applications][APPLICATIONS] folder.
