-@group config
-
-Arcanist uses certificates to authenticate to Phabricator. Usernames and
-certificates for each host you have credentials on are stored in your
-##~/.arcrc## file under the "hosts" key. The configuration should look something
-like this:
-
-  {
-    # ...
-    "hosts" : {
-      "http://phabricator.example.com/api/" : {
-        "user" : "alincoln",
-        "cert" : "Y2FTilanoONuPzAtXayoctmX6FmIt7QjxXhWVAv2EoWpeik1Deecl3jRo"
-      }
-      # If you have accounts on more than one host, add them here.
-    }
-  }
-
-To retrieve the certificate for a Phabricator host:
-
-  - Login to Phabricator. **Make sure you log into the installation you are
-    trying to install a certificate for!** If you are installing a certificate
-    for ##phabricator.example.com##, you need to log into
-    ##phabricator.example.com##, **not** ##secure.phabricator.com##.
-  - Go to Settings (upper right, near Search) > Arcanist Certificate.
-
-Copy the host info including the certificate into the "hosts" section.
