 You will by default be managing a patch queue named "patches". You can
 create other, independent patch queues with the :hg:`qqueue` command.
+
+If the working directory contains uncommitted files, qpush, qpop and
+qgoto abort immediately. If -f/--force is used, the changes are
+discarded. Setting:
+
+  [mq]
+  check = True
+
+make them behave as if -c/--check were passed, and non-conflicting
+local changes will be tolerated and preserved. If incompatible options
+such as -f/--force or --exact are passed, this setting is ignored.
