-# 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"
-    ports:
-      - "7092:7092"
-    ```

-## Enable Aikar's Flags
-
-[Aikar has done some research](https://aikar.co/2018/07/02/tuning-the-jvm-g1gc-garbage-collector-flags-for-minecraft/) into finding the optimal JVM flags for GC tuning, which becomes more important as more users are connected concurrently. [PaperMC also has an explanation](https://docs.papermc.io/paper/aikars-flags) of what the JVM flags are doing.
-
-The set of flags documented there can be added using
-
-    -e USE_AIKAR_FLAGS=true
-
-When `MEMORY` is greater than or equal to 12G, then the Aikar flags will be adjusted according to the article.
-
-## Enable MeowIce's Flags
-
-[MeowIce has created an updated set of JVM flags](https://github.com/MeowIce/meowice-flags?tab=readme-ov-file#why-would-i-have-to-switch-) based on Aikar's flags but with support for optimizations for Java 17 and above
-
-The set of flags documented there can be added using
-
-    -e USE_MEOWICE_FLAGS=true
-
-There is an optional `USE_MEOWICE_GRAALVM_FLAGS` variable to enable GraalVM specific optimizations, defaults to `TRUE` if USE_MEOWICE_GRAALVM_FLAGS is `TRUE`
