+## Adding a server type
+
+Adding a new server `TYPE` can vary due to the complexity of obtaining and configuring each type; however, the addition of any server type includes at least the following steps:
+
+1. Copy an existing "start-deploy*" script, such as [start-deployMohist](start-deployMohist) and rename it accordingly making sure to retain the "start-deploy" prefix
+2. Modify the type-specific behavior between the "start-utils" preamble and the hand-off to `start-finalSetupWorld` at the end of the script 
+3. Develop and test the changes using the [iterative process described below](#iterative-script-development)
+4. Add a case-entry to the `case "${TYPE^^}"` in [start-configuration](start-configuration)
+5. Add a section to the [README](README.md). It is recommended to copy-modify an existing section to retain a similar wording and level of detail
+6. [Submit a pull request](https://github.com/itzg/docker-minecraft-server/pulls)
+
+## Iterative script development
+
+Individual scripts can be iteratively developed, debugged, and tested using the following procedure.
+
+First, build a baseline of the image to include the packages needed by existing or new scripts:
+
+```shell script
+docker build -t mc-dev .
+```
+
+Using the baseline image, an interactive container can be started to iteratively run the scripts to be developed. By attaching the current workspace directory, you can use the local editor of your choice to iteratively modify scripts while using the container to run them.
+
+```shell script
+docker run -it --rm -v ${PWD}:/scripts -e SCRIPTS=/scripts/ --entrypoint bash mc-dev
+```
+
+From within the container you can run individual scripts via the attached `/scripts/` path; however, be sure to set any environment variables expected by the scripts by either `export`ing them manually:
+
+```shell script
+export VANILLA_VERSION=1.12.2
+/scripts/start-magma
+```
+
+...or pre-pending script execution:
+
+```shell script
+VANILLA_VERSION=1.12.2 /scripts/start-magma
+```
+
+> NOTE: You may want to temporarily add an `exit` statement near the end of your script to isolate execution to just the script you're developing.
+
+## Multi-base-image variants
+
+Several base-image variants are maintained in order to offer choices in JDK provider and version. The variants are maintained in their respective branches:
+- openj9 
+- openj9-nightly
+- adopt11
+- adopt13
+- multiarch
+
+The [docker-versions-create.sh](docker-versions-create.sh) script is configured with the branches to maintain and is used to merge changes from the master branch into the mulit-base variant branches. The script also manages git tagging the master branch along with the merged branches. So a typical use of the script would be like:
+
+```shell script
+./docker-versions-create.sh -s -t 1.2.0
+```
+
+> Most often the major version will be bumped unless a bug or hotfix needs to be published in which case the patch version should be incremented.
+
+> The build and publishing of those branches and their tags is currently performed within Docker Hub.
+
+## multiarch support
+
+The [multiarch branch](https://github.com/itzg/docker-minecraft-server/tree/multiarch) supports running the image on amd64, arm64, and armv7 (aka RaspberryPi). Unlike the mainline branches, it is based on Ubuntu 18.04 since the openjdk package provided by Ubuntu includes full JIT support on all of the processor types.
+
+The multiarch images are built and published by [a Github action](https://github.com/itzg/docker-minecraft-server/actions?query=workflow%3A%22Build+and+publish+multiarch%22), which [is configured in that branch](https://github.com/itzg/docker-minecraft-server/blob/multiarch/.github/workflows/build-multiarch.yml).
+
+## Generating release notes
+
+The following git command can be used to provide the bulk of release notes content:
+
+```shell script
+git log --invert-grep --grep "^ci:" --grep "^misc:" --grep "^docs:" --pretty="- %s" 1.1.0..1.2.0
+```

+
+## 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.
+
+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.
+
+A starting, example compose file has been provided in [examples/docker-compose-autopause.yml](examples/docker-compose-autopause.yml).
+
+### Enabling Autopause
+
+Enable the Autopause functionality by setting:
+
+```
+-e ENABLE_AUTOPAUSE=TRUE
+```
+
+There are 4 more environment variables that define the behaviour:
+* `AUTOPAUSE_TIMEOUT_EST`, default `3600` (seconds)
+describes the time between the last client disconnect and the pausing of the process (read as timeout established)
+* `AUTOPAUSE_TIMEOUT_INIT`, default `600` (seconds)
+describes the time between server start and the pausing of the process, when no client connects inbetween (read as timeout initialized)
+* `AUTOPAUSE_TIMEOUT_KN`, default `120` (seconds)
+describes the time between knocking of the port (e.g. by the main menu ping) and the pausing of the process, when no client connects inbetween (read as timeout knocked)
+* `AUTOPAUSE_PERIOD`, default `10` (seconds)
+describes period of the daemonized state machine, that handles the pausing of the process (resuming is done independently)

-If you use something like CurseForge, you may end up creating/using modpacks that do not
-contain server mod jars. Instead, the CurseForge setup has `manifest.json` files, which
-will show up under `/data/FeedTheBeast/manifest.json`.
-
-To use these packs you will need to:
-
-- Specify the manifest location with env var `MANIFEST=/data/FeedTheBeast/manifest`
-- Pick a relevant ServerStart.sh and potentially settings.cfg and put them in `/data/FeedTheBeast`
-
-An example of the latter would be to use <https://github.com/AllTheMods/Server-Scripts>
-There, you'll find that all you have to do is put `ServerStart.sh` and `settings.cfg` into
-`/data/FeedTheBeast`, taking care to update `settings.cfg` to specify your desired version
-of minecraft and forge. You can do this in the cli with something like:
-
-```
-$ wget https://raw.githubusercontent.com/AllTheMods/Server-Scripts/master/ServerStart.sh
-$ wget https://raw.githubusercontent.com/AllTheMods/Server-Scripts/master/settings.cfg
-$ vim settings.cfg #update the forge version to the one you want. Your manifest.json will have it
-$ chmod +x ServerStart.sh
-$ docker run -itd --name derpcraft \
-  -e MANIFEST=/data/FeedTheBeast/manifest.json \
-  -v $PWD/ServerStart.sh:/data/FeedTheBeast/ServerStart.sh \

-  -e EULA=TRUE\
-  --restart=always\
-  itzg/minecraft-server
-```
-
-Note the `CF_SERVER_MOD` env var should match the server version of the modpack you are targeting.
