-How this all fits together
---------------------------
-
-Let's look at a hypothetical example for how this all first together. Imagine,
-if you will, a point about halfway between 1.5 and 1.6. At this point,
-development will be happening in a bunch of places:
-
-* On master, development towards 1.6 proceeds with small additions, bugs
-  fixes, etc. being checked in daily.
-
-* On the branch ``stable/1.5.x``, fixes for critical bugs found in
-  the 1.5 release are checked in as needed. At some point, this branch will
-  be released as "1.5.1", "1.5.2", etc.
-
-* On the branch ``stable/1.4.x``, security fixes are made if
-  needed and released as "1.4.2", "1.4.3", etc.
-
-* Development of major features is done in branches in forks of the main
-  repository. These branches will be merged into ``master`` before "1.6
-  alpha 1".
