-# JVM Options
-
-## Memory Limit
-
-By default, the image declares an initial and maximum Java memory-heap limit of 1 GB. There are several ways to adjust the memory settings:
-
-- `MEMORY`: "1G" by default, can be used to adjust both initial (`Xms`) and max (`Xmx`) memory heap settings of the JVM
-- `INIT_MEMORY`: independently sets the initial heap size
-- `MAX_MEMORY`: independently sets the max heap size
-
-The values of all three are passed directly to the JVM and support format/units as `<size>[g|G|m|M|k|K]`.
-
-!!! example "Using docker run"
-
-    ```
-        -e MEMORY=2G
-    ```
-
-    or to use init and max memory:
-
-    ```
-        -e INIT_MEMORY=1G -e MAX_MEMORY=4G
-    ```
-
-!!! example "Using compose file"
-
-    ```
-        environment:
-          MEMORY: 2G
-    ```
-
-    or to use init and max memory:
-
-    ```
-        environment:
-          INIT_MEMORY: 1G
-          MAX_MEMORY: 4G
-    ```
-
-To let the JVM calculate the heap size from the container declared memory limit, unset `MEMORY` with an empty value, such as `-e MEMORY=""`. By default, the JVM will use 25% of the container memory limit as the heap limit; however, as an example the following would tell the JVM to use 75% of the container limit of 4GB of memory:
-
-!!! example "MaxRAMPercentage using compose file"
-
-    ```
-        environment:
-          MEMORY: ""
-          JVM_XX_OPTS: "-XX:MaxRAMPercentage=75"
-        deploy:
-          resources:
-            limits:
-              memory: 4G
-    ```
-
-!!! important
-    The settings above only set the Java **heap** limits. Memory resource requests and limits on the overall container should also account for non-heap memory usage. An extra 25% is [a general best practice](https://dzone.com/articles/best-practices-java-memory-arguments-for-container).
-
-## Extra JVM Options
-
-General JVM options can be passed to the Minecraft Server invocation by passing a `JVM_OPTS`
-environment variable. The JVM requires `-XX` options to precede `-X` options, so those can be declared in `JVM_XX_OPTS`. Both variables are space-delimited, raw JVM arguments.
-
-```
-docker run ... -e JVM_OPTS="-someJVMOption someJVMOptionValue" ...
-```
-
-**NOTE** When declaring `JVM_OPTS` in a compose file's `environment` section with list syntax, **do not** include the quotes:
-
-```yaml
-    environment:
-      - EULA=true
-      - JVM_OPTS=-someJVMOption someJVMOptionValue
-```
-
-Using object syntax is recommended and more intuitive:
-
-```yaml
-    environment:
-      EULA: "true"
-      JVM_OPTS: "-someJVMOption someJVMOptionValue"
-# or
-#     JVM_OPTS: -someJVMOption someJVMOptionValue
-```
-
-As a shorthand for passing several system properties as `-D` arguments, you can instead pass a comma separated list of `name=value` or `name:value` pairs with `JVM_DD_OPTS`. (The colon syntax is provided for management platforms like Plesk that don't allow `=` inside a value.)
-
-For example, instead of passing
-
-```yaml
-  JVM_OPTS: -Dfml.queryResult=confirm -Dname=value
-```
-
-you can use
-
-```yaml
-  JVM_DD_OPTS: fml.queryResult=confirm,name=value
-```

-## Enable Remote JMX for Profiling
-
-To enable remote JMX, such as for profiling with VisualVM or JMC, set the environment variable `ENABLE_JMX` to "true", set `JMX_HOST` to the IP/host running the Docker container, and add a port forwarding of TCP port 7091, such as:
-
-!!! example
-
-    With `docker run`
-
-    ```
-    -e ENABLE_JMX=true -e JMX_HOST=$HOSTNAME -p 7091:7091
-    ```
-
-If needing to map to a different port, then also set the environment variable `JMX_PORT` to the desired host port.
-
-!!! example
-
-    With a compose file:
-
-    ```yaml
-    environment:
-      ENABLE_JMX: true
-      JMX_HOST: ${HOSTNAME}
-      JMX_PORT: "7092"

+!!! important
+
+    As of [1.21.2](https://minecraft.wiki/w/Java_Edition_1.21.2) it is not recommend to use this feature since Minecraft server natively auto-pauses when the server is empty. That is configured via the enivironment variable `PAUSE_WHEN_EMPTY_SECONDS`, which maps to the `pause-when-empty-seconds` server property. 
 
 An auto-pause functionality is provided that monitors whether clients are connected to the server. If a client is not connected for a specified time, the Java process is put into a pause state. When a client attempts to connect while the process is paused, then process will be restored to a running state. The experience for the client does not change. This feature can be enabled by setting the environment variable `ENABLE_AUTOPAUSE` to "true".

+This container disables health checks for Minecraft versions before b1.8 as those versions do not support any kind of server pinging. For more information see [Server List Ping](https://minecraft.wiki/w/Java_Edition_protocol/Server_List_Ping#Beta_1.8_to_1.3).

+## Version from Projects
+
+When the environment variable `VERSION_FROM_MODRINTH_PROJECTS` is set to "true" the Minecraft [`VERSION`](../versions/minecraft.md) will be automatically determined by looking at the most recent version of Minecraft that is supported by all the projects provided in `MODRINTH_PROJECTS`.
+
+!!! example
+
+    Given the environment variables
+    
+    ```yaml
+        MODRINTH_PROJECTS: |
+          viaversion
+          viabackwards
+          griefprevention
+          discordsrv
+        VERSION_FROM_MODRINTH_PROJECTS: true
+    ```
+    
+    Let's say all are supported on Minecraft up to 1.21.8 except griefprevention, which is only supported up to 1.21.7. In that case, `VERSION` will be automatically set to 1.21.7.

 Notes
 
 1. Why no arm64 for Java 17 Alpine? That is because the base images, such as [elipse-temurin](https://hub.docker.com/_/eclipse-temurin/tags?page=&page_size=&ordering=&name=17-jre-alpine) do not provide support for that. Use the Ubuntu based images instead.
 2. Short-term variant, subject to deprecation upon next version introduction
 3. Based on the [Oracle GraalMV images](https://blogs.oracle.com/java/post/new-oracle-graalvm-container-images), which as of JDK 17, are now under the [GraalVM Free License](https://blogs.oracle.com/java/post/graalvm-free-license) incorporating what used to be known as the GraalVM Enterprise.
