+How to contribute to Amtk
+=========================
 
-Contributions are no longer accepted
-------------------------------------
+Amtk follows the same guidelines and code conventions as GtkSourceView:
 
-And new maintainers are not accepted either.
-
-But the source code is open, you can copy it freely and create a new project.
-What I just ask for the new project:
-- Must have a different project name.
-- And it must be possible to install Amtk plus the new project in parallel on
-  the same prefix. For example by just bumping the major/API version of the
-  library to something far apart.
