-## 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).

-To install all of the server content (jars, mods, plugins, configs, etc) from a zip file, such as a CurseForge modpack that is missing a server start script, then set `GENERIC_PACK` to the container path of the zip file. That, combined with `TYPE`, allows for custom content along with container managed server download and install.  
+**NOTE:** This potentially could lead to unexpected behavior if the Mod receives an update with unexpected behavior.
 
-If multiple generic packs need to be applied together, set `GENERIC_PACKS` instead, with a comma separated list of zip file paths and/or URLs to zip files.
+This is more complicated because you will be pulling/using the latest mod for the release of your game. To get started make sure you have a [CursedForge API Key](https://docs.curseforge.com/#getting-started). Then use the environmental parameters in your docker build.
+
+Please be aware of the following when using these options for your mods:
+* Mod Release types: Release, Beta, and Alpha.
+* Mod dependencies: Required and Optional
+* Mod family: Fabric, Forge, and Bukkit.
+
+Parameters to use the ForgeAPI:
+
+* `MODS_FORGEAPI_KEY` - Required
+* `MODS_FORGEAPI_FILE` - Required or use MODS_FORGEAPI_PROJECTIDS (Overrides MODS_FORGEAPI_PROJECTIDS)
+* `MODS_FORGEAPI_PROJECTIDS` - Required or use MODS_FORGEAPI_FILE
+* `MODS_FORGEAPI_RELEASES` - Default is release, Options: [Release|Beta|Alpha]
+* `MODS_FORGEAPI_DOWNLOAD_DEPENDENCIES` - Default is False, attempts to download required mods (releaseType Release) defined in Forge.
+* `MODS_FORGEAPI_IGNORE_GAMETYPE` - Default is False, Allows for filtering mods on family type: FORGE, FABRIC, and BUKKIT. (Does not filter for Vanilla or custom)
+* `REMOVE_OLD_FORGEAPI_MODS` - Default is False
+* `REMOVE_OLD_DATAPACKS_DEPTH` - Default is 1
+* `REMOVE_OLD_DATAPACKS_INCLUDE` - Default is *.jar
+
+Example of expected forge api project ids, releases, and key:

+```
+
+Example of expected ForgeAPI file format.
+
+**Field Description**: 
+* `name` is currently unused, but can be used to document each entry.
+* `projectId` id is the id found on the CurseForge website for a particular mod
+* `releaseType` Type corresponds to forge's R, B, A icon for each file. Default Release, options are (release|beta|alpha).
+* `fileName` is used for version pinning if latest file will not work for you.

+
+### Generic pack files
+
+To install all the server content (jars, mods, plugins, configs, etc.) from a zip or tgz file, then set `GENERIC_PACK` to the container path or URL of the archive file. This can also be used to apply a CurseForge modpack that is missing a server start script and/or Forge installer.
+
+If multiple generic packs need to be applied together, set `GENERIC_PACKS` instead, with a comma separated list of archive file paths and/or URLs to files.
+
+To avoid repetition, each entry will be prefixed by the value of `GENERIC_PACKS_PREFIX` and suffixed by the value of `GENERIC_PACKS_SUFFIX`, both of which are optional. For example, the following variables
+
+```
+GENERIC_PACKS=configs-v9.0.1,mods-v4.3.6
+GENERIC_PACKS_PREFIX=https://cdn.example.org/
+GENERIC_PACKS_SUFFIX=.zip
+```
+
+would expand to `https://cdn.example.org/configs-v9.0.1.zip,https://cdn.example.org/mods-v4.3.6.zip`.
+
+If applying large generic packs, the update check can be time-consuming since a SHA1 checksum is compared. To skip the update check set `SKIP_GENERIC_PACK_UPDATE_CHECK` to "true". Conversely, the generic pack(s) can be forced to be applied without comparing the checksum by setting `FORCE_GENERIC_PACK_UPDATE` to "true".

 For some cases, if e.g. after removing mods, it could be necessary to startup minecraft with an additional `-D` parameter like `-Dfml.queryResult=confirm`. To address this you can use the environment variable `JVM_DD_OPTS`, which builds the params from a given list of values separated by space, but without the `-D` prefix. To make things running under systems (e.g. Plesk), which doesn't allow `=` inside values, a `:` (colon) could be used instead. The upper example would look like this:
