+# Nextcloud
 The pride and joy of my project! 
 This docker-compose installs Nextcloud, OnlyOffice and associated with the coturn server that you can find on this git, video and audio calls based on "Talk".
 Link to the Nextcloud project: https://github.com/nextcloud
 
 ## Video and audio calls
+Once this docker and coturn (https://git.lescourts.fr/dim/Infra_docker/src/branch/main/coturn) are deployed, here is what you need to do on Nextcloud settings to make video and audio calls working:
+### Server STUN
+Actually you can let the default value: stun.nextcloud.com:443
+
+### Server TURN
+ - turn only
+ - URL: <your turn domain defined in the .env file of your coturn server, SUBDOMAIN and DOMAIN>:3478
+ - Password: <the STATIC_AUTH_SECRET of you coturn's .env file>
+ - TCP and UDP: makes it more flexible
