 ## Usage
 
 ### Infos
   
-The script does look for an sqlite db in the linked host-folder. 
-If its found, a symlink is created to the ts3-folder inside the container. 
-This means the server should use your old ts3 db if present. 
-If not present it will create a new one, right now this will NOT be created under the linked host-folder!
-The problem here is i cant tell the TS3 server to create the db in specific folder.
-Creating a empty file and then linking this did not work either since TS3 is then complaining its no sqlite db.

-Script will also look for ts3server.ini in linked host-folder. This file will also be created if its not 
-found since TS3-server has a paramater for that. If you use your own ini-file you may want to link logs and other data to /teamspeak3.
-This way you can mount the directory and backup/persist the data even when upgrading.

 ### Create container
     
-This creates and starts a docker container in the 
-background (-d) with 
-direct mapping of the TS3 port (-p 9987:9987/udp)
-and sets the name to TS3.
-{FOLDER} is an absolute path on the host to be mapped by the containers /teamspeak3 folder.
-Injected files are used from this location, see Summary above.
+This creates and starts a docker container in the background (`-d`) with direct mapping of the TS3 port (`-p 9987:9987/udp`) and sets the name to TS3. `{FOLDER}` is an absolute path on the host to be mapped by the containers /teamspeak3 folder. Injected files are used from this location, see Summary above.
 
+Starting in version 3.1.0 Teamspeak needs you to accept the license included with the server. To accept the license pass `-e TS3SERVER_LICENSE=accept` to the command or create a `.ts3server_license_accepted` file in your `{FOLDER}`.
+
+To review the license execute this command:
+
+```bash
+$ docker run --rm --entrypoint /bin/cat luzifer/teamspeak3 /opt/teamspeak3-server_linux_amd64/LICENSE | less
 ```
-$ docker run --name TS3 -d -p 9987:9987/udp -v {FOLDER}:/teamspeak3 luzifer/teamspeak3
+
+Putting everything together this is how you will start your server:
+
+```bash
+# Optionally create license accept file
+$ touch {FOLDER}/.ts3server_license_accepted
+
+# Start container
+$ docker run --name TS3 -d -e TS3SERVER_LICENSE=accept -p 9987:9987/udp -v {FOLDER}:/teamspeak3 luzifer/teamspeak3
 ```
     
 ### Admin Secret
   
 After starting the container you probably want to get the Admin secret with:
 
-```
+```bash
 $ docker logs TS3
 ```
     
 ### Upgrading
   
-Just stop and remove the old container, then start again at "Creating container". You may have to pull the image again if its not updating.
-CAUTION: Didnt test if all files are really persisted or if the TS3 process overwrites some files. So make sure you have a backup.
