 The first remote, github is the leader. The others are followers that are updated.
 
+## Automate
+To automate mirroring, run it periodically, for example once every 30 minutes. On a *NIX you could

 ## Tor
 The leader is fetched over Tor through torify. Make sure Tor is running, or edit the script,
 changing `torify git fetch` into `git fetch`.
