+### Who Does Mercurial Trust?
+As you start to use Mercurial more and more, you may eventually run into error
+messages that look like this:
+ Not trusting file /home/alice/repo/.hg/hgrc from untrusted user alice, group users

+`hgrc` file that it would normally use, but it's owned by someone else that may
+have made nefarious changes to it.
+To learn more about this situation you should take a look at the [Trust] page
