+### Login to conduit
+
+[Integration into the yunohost user database is not ready, yet.](https://github.com/YunoHost-Apps/conduit_ynh/issues/12) You need to **enable registration** in the apps configuration tab and then use a client to register an account. Afterwards you can disable registration again if you do not want allow anybody to register.
+
+Using the newly created account you should be able to login.
+
+###  Coturn configuration
+
+To be able to take advantage of audio and video call functionalities, a coturn server is often required. It is possible to [install a coturn server in YunoHost (https://github.com/YunoHost-Apps/coturn-ynh/blob/master/README-en.md).
+It is then necessary to fill in the information provided by the coturn server in the file 'conduit.toml' such as:
+
+```
+turn_uris = ["turns:your.turn.url:5349?transport=udp", "turns:your.turn.url:5349?transport=tcp"]
+turn_username = "<YOUR_USERNAME>"
+turn_password = "<YOUR_PASSWORD>"
+```
+If your coturn (not Yunohost's one) don't use TLS, you might need to change a little bit like :
+```
+turn_uris = ["turn:your.turn.url:5349?transport=udp", "turn:your.turn.url:5349?transport=tcp"]
+``
