 * `AUTOPAUSE_KNOCK_INTERFACE`, default `eth0`
   <br>Describes the interface passed to the `knockd` daemon. If the default interface does not work, run the `ifconfig` command inside the container and derive the interface receiving the incoming connection from its output. The passed interface must exist inside the container. Using the loopback interface (`lo`) does likely not yield the desired results.
 
-## Autostop
-
-An option to stop the server after a specified time has been added for niche applications (e.g. billing saving on AWS Fargate). The function is incompatible with the Autopause functionality, as they basically cancel out each other.
-
-Note that the docker container variables have to be set accordingly (restart policy set to "no") and that the container has to be manually restarted.
-
-A starting, example compose file has been provided in [examples/docker-compose-autostop.yml](examples/docker-compose-autostop.yml).
-
-Enable the Autostop functionality by setting:
-
-```
--e ENABLE_AUTOSTOP=TRUE
-```
-
-The following environment variables define the behaviour of auto-stopping:
-* `AUTOSTOP_TIMEOUT_EST`, default `3600` (seconds)
-  describes the time between the last client disconnect and the stopping of the server (read as timeout established)
-* `AUTOSTOP_TIMEOUT_INIT`, default `1800` (seconds)
-  describes the time between server start and the stopping of the server, when no client connects inbetween (read as timeout initialized)
-* `AUTOSTOP_PERIOD`, default `10` (seconds)
-  describes period of the daemonized state machine, that handles the stopping of the server
