+(Especially) when you want to use additional features of EasyBuild, such as the
+[GitHub integration](https://docs.easybuild.io/integration-with-github/),
+ you might need to set a specific Python version to use by EasyBuild.
+
+That is unrelated to any Python module you might wish to use or install!
+Furthermore, when using EasyBuild you should **not** have any other modules loaded,
+not even `Python`.
+
+Which Python executable is used by EasyBuild can be shown by executing:
+
+```console
+marie@compute$ EB_VERBOSE=1 eb --version
+```
+
+You can change it by setting `EB_PYTHON`, e.g.:
+
+```console
+marie@compute$ export EB_PYTHON=python3.8
+```
+
+In case you are using a virtualenv for use with EasyBuild
+then using `python` instead of `python3.8` or similar is enough
+as there will be a `python` binary available inside your virtualenv.
