+@section How to make a Source Plugin
+
+To be automatically mergable it is important to keep all changes clean and well separated.
+If you want to create a new source plugin, look at an existing one, or simply fork FFmpeg,
+name the repository "sourceplugin-..." and add it to tools/merge-all-source-plugins
+and try running it. Also check that it works with the latest releases.
