 Use the admin panel of your discourse to configure this app.
 
+### Configuring "Reply-By-Email"
+
+* You should create a dedicated Yunohost user for Discourse whose mailbox will be used by the Discourse application. You can do this with `yunohost user create response`, for example. You should ensure that the email address is configured to be on your Discourse domain.
+
+* You should then configure your Discourse `/var/www/discourse/config/discourse.conf` file with the correct SMTP configuration values. Please see [this comment](https://github.com/YunoHost-Apps/discourse_ynh/issues/2#issuecomment-409510325) for an explanation of what values to change. Please be aware, when you update the application, you will have to re-apply this configuration.
+
+* You must enable the Pop3 configuration for Dovecot. See [this thread](https://forum.yunohost.org/t/how-to-enable-pop3-in-yunohost/1662/2) on how to do that. You can validate your configuration with `systemctl restart dovecot && dovecot -n`. Don't forget to open the ports you need (`995` is the default). You can validate that with `nmap -p 995 yunohostdomain.org`.
+
+* You should then configure the Pop3 polling in the Discourse admin interface. Please see [this comment](https://meta.discourse.org/t/set-up-reply-via-email-support/14003) for how to do so. You will need to follow step 5 in that comment. You can specify your main Yunohost domain for the `pop3_polling_host`.
+
+You should now be able to start testing. Try using the `/admin/email` "Send Test Email" and then view the "Sent" or "Skipped" etc. tabs. You should see a report on what happened with the email. You may also want to look in `/var/www/discourse/log/production.log` as well as `/var/www/mail.err`. You should perhaps also use [Rainloop](https://github.com/YunoHost-Apps/rainloop_ynh) or another Yunohost email client application to quickly test that both your user and the dedicated Yunohost Discourse user (`response@...`) is receiving mail.
