1. General Git tips that no longer applies with the GNOME infrastructure
But can still be useful.
1.1. cgit Atom/RSS feed
Use the cgit URL that you would like to subscribe to in your feed reader, for example:
http://git.gnome.org/browse/glib/atom/?h=master
for the Atom feed of the master branch of GLib.
Alternatively, your web browser should show any available feeds if you are viewing cgit commit logs.
Update: cgit is no longer used in GNOME, it has been replaced by GitLab.
