-To start an installed Wired server, run:
-
-	/usr/local/wired/wiredctl start
-
 By default a user with the login "admin" and no password is created. Use Wired Client or Wire to connect to your newly installed Wired Server. 
 
-### Running on Docker
-
-Pull and run the container:
+Wired is compiled as foreground Task in Debug mode. Thats why you nee to run it in a screen-Session.
+If you run it in Daemon Mode your CPU will going crazy after some time (100% usage).
 
-    docker run --name wired -d -p 4871:4871 -v /path/to/yours/files:/files wired2/wired:2.5
-
-* the `-p` option maps the container port (`4871`) to whatever the port you want to use on your host machine. If you want `wired` to be available on another you can use: `10000:4871` and Docker will translate it.
-* the `-v` option maps items of the container file system with your local file system. You can change the first value of the pair to adjust to your server files configuration. Wired Server will look into the `/files` path of the container to index and server your files. 
-
-If you want Docker to start the container automatically for you, add the `--restart always` argument as follow:
-
-    docker run --name wired --restart always -d -p 4871:4871 -v /path/to/yours/files:/files wired2/wired:2.5
-
-Start/stop the container:
+To start an installed Wired server, run:
 
-    docker stop wired
-    docker start wired
-    
-Remove the container:
+	screen -Sdm wired /usr/local/wired/wiredctl start
 
-    docker rm wired
-    
-It could be useful to backup and restore container files such as `database.sqlite3` or `wired.conf`. You can do that do using the `docker cp` command.
-    
-From container to host:
-    
-    docker cp wired:/user/local/wired/database.sqlite3 /path/to/your/database.sqlite3
+To enter the running screen session (wiredctl) simply type:
