+Single head enforcing
+=====================
+
+The extensions come with an option to enforce that there is only one heads for
+each name in the repository at any time.
+
+    [experimental]
+    enforce-single-head = yes
+
+Publishing behavior
+===================
+
+Topic vanish when changeset move to the public phases. Moving to the public
+phase usually happens on push, but it is possible ot update that behavior. The
+server needs to have specific config for this.
+
+    # everything pushed become public (the default)
+    [phase]
+    publish = yes
+
+    # nothing push turned public
+    [phase]
+    publish = no
+
+    # topic branches are not published, changeset without topic are
+    [phase]
+    publish = no
+    [experimental]
+    topic.publish-bare-branch = yes
+
+In addition, the topic extension adds a ``--publish`` flag on :hg:`push`. When
+used, the pushed revisions are published if the push succeeds. It also applies
+to common revisions selected by the push.
