-How to contribute to Amtk
-=========================
+Amtk development
+================
 
-Amtk follows the same guidelines and code conventions as GtkSourceView:
+Contributions are no longer accepted
+------------------------------------
 
-    https://gitlab.gnome.org/GNOME/gtksourceview/blob/master/HACKING
+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.

+Notes

+Amtk follows the same guidelines and code conventions as GtkSourceView (when
+GtkSourceView was still developed by Sébastien Wilmet).
