-(evolve's stable and default branches correspond to Mercurial's stable
-and default branches. So to test evolve from default, you need
-Mercurial on default.), Older version of Mercurial are supportd on their respective ``mercurial-x.y`` branches.
+Branch policy
+-------------
+
+The evolve test are highly impacted by changes in core. To deal with this, we use named branches.
+
+There are two main branches: "stable" and "default". Tests on these branch are
+supposed to pass with the corresponding "default" and "stable" branch from core
+Mercurial. The documentation is built from the tip of stable.
+
+In addition, we have compatibility branches to check tests on older version of
+Mercurial. They are the "mercurial-x.y" branches. They are used to apply
+expected test change only, no code change should happen there.
