+How to set up a buildbot worker
+================================
+
+* Create a Python venv for the buildbot worker, and populate it with the
+  buildbot-worker and dependent packages:
+
+      cd ~/.myPyEnv
+      python3.8 -m venv Py38-bb2
+      source Py38-bb2/bin/activate
+      pip install buildbot-worker
+
+
+* Add a project folder, like bb2, that will be the base folder for the buildbot
+  worker and the venvs used for the builds.
+
+* Set up venvs for each Python to be supported on this platform. They should be
+  located in the bb2 folder, and named like "venv-3.8"
+
+* Add configuration for the new worker in master.cfg, and update the server.
+
+* Create the worker config using:
+
+      buildbot-worker create-worker . buildbot.wxpython.org:9988 <name> <passwd>
+
+* Add start and stop scripts, like these:
+
+      #!/bin/bash
+      source ~/bin/wrangler.sh Py38-bb2
+      echo "(Re)starting the buildbot-worker"
+      buildbot-worker restart .
+
+
+      #!/bin/bash
+      source ~/bin/wrangler.sh Py38-bb2
+      echo "Stopping the buildbot-worker"
+      buildbot-worker stop .
