+Config
+======
+If you'd like the packaged Riot to have a configuration file, you can create a
+config directory and place `config.json` in there, then specify this directory
+with the `--cfgdir` option to `yarn run fetch`, eg:
+```
+mkdir myconfig
+cp /path/to/my/config.json myconfig/
+yarn run fetch --cfgdir myconfig
+```
+The config dir for the official Riot.im app is in `riot.im`. If you use this,
+your app will auto-update itself using builds from Riot.im.
