-## Autopause
+## Autopause (experimental)
 
 ### Description
 
+> EXPERIMENTAL: this feature only works with default bridge networking using official Docker distributions. Host networking and container management software, such as Portainer, and NAS solutions do not seem to provide compatible networking.
+
 There are various bug reports on [Mojang](https://bugs.mojang.com) about high CPU usage of servers with newer versions, even with few or no clients connected (e.g. [this one](https://bugs.mojang.com/browse/MC-149018), in fact the functionality is based on [this comment in the thread](https://bugs.mojang.com/browse/MC-149018?focusedCommentId=593606&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-593606)).
 
 An autopause functionality has been added to this image to monitor whether clients are connected to the server. If for a specified time no client is connected, the Java process is stopped. When knocking on the server port (e.g. by the ingame Multiplayer server overview), the process is resumed. The experience for the client does not change.
 
 Of course, even loaded chunks are not ticked when the process is stopped.
 
-From the server's point of view, the pausing causes a single tick to take as long as the process is stopped, so the server watchdog might intervene after the process is continued, possibly forcing a container restart. To prevent this, ensure that the `max-tick-time` in the `server.properties` file is set correctly. Non-vanilla versions might have their own configuration file, you might have to disable their watchdogs separately (e.g. PAPER Servers).
+From the server's point of view, the pausing causes a single tick to take as long as the process is stopped, so the server watchdog might intervene after the process is continued, possibly forcing a container restart. To prevent this, ensure that the `max-tick-time` in the `server.properties` file is set correctly.
 
 On startup the `server.properties` file is checked and, if applicable, a warning is printed to the terminal. When the server is created (no data available in the persistent directory), the properties file is created with the Watchdog disabled.
 
-The utility used to wake the server (`knock(d)`) works at network interface level. So the correct interface has to be set using the `AUTOPAUSE_KNOCK_INTERFACE` variable when using non-default networking environments (e.g. host-networking, Portainer oder NAS solutions). See the description of the variable below.

If you are running a `BUKKIT` distribution this will affect all files inside the `plugins/` directory. You can fine tune the removal process by specifing the `REMOVE_OLD_MODS_INCLUDE` and `REMOVE_OLD_MODS_EXCLUDE` variables. By default everything will be removed. You can also specify the `REMOVE_OLD_MODS_DEPTH` (default 16) variable to only delete files up to a certain level.

 This works well if you want to have a common set of modules in a separate
 location, but still have multiple worlds with different server requirements
 in either persistent volumes or a downloadable archive.
 
-You can specify the destination of the configs that are located inside the `/config` mount by setting the `COPY_CONFIG_DEST` variable. The configs are copied recursivly to the `/data/config` directory by default. If a file was updated directly inside the `/data/*` directoy and is newer than the file in the `/config/*` mount it will not be overriden.
 
-> For example: `-v ./config:/config -e COPY_CONFIG_DEST=/data` will allow you to copy over your `bukkit.yml` and so on directly into the server directory.
