-#### Auth Token
-You can enter your auth token on your computer by saving an empty token. Then quit KOReader, edit the `exporter.joplin_token` field in `settings.reader.‍lua` after creating a backup, and restart KOReader once you're done.
 
-#### Port Forwarding
-To export to Joplin, you must forward the IP and port used by this plugin to the `localhost:port` on which Joplin is listening. This can be done with `socat` or a similar program. For example:
