 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

+### Using Docker Compose
+
+Rather than type the server options below, the port mappings above, etc
+every time you want to create new Minecraft server, you can now use
+[Docker Compose](https://docs.docker.com/compose/). Start with a
+`docker-compose.yml` file like the following:
+
+```yml
+version: "3"
+
+services:
+  mc:
+    image: itzg/minecraft-server
+    ports:
+      - 25565:25565
+    environment:
+      EULA: "TRUE"
+    tty: true
+    stdin_open: true
+    restart: unless-stopped
+```
+
+and in the same directory as that file run
+
+    docker-compose up -d
+
+Now, go play...or adjust the `environment` section to configure
+this server instance.
+
+## Troubleshooting
+
+To troubleshoot the container initialization, such as when server files are pre-downloaded, set the environment variable `DEBUG` to `true`. The container logs will include **much more** output, and it is highly recommended including that output when reporting any [issues](https://github.com/itzg/docker-minecraft-server/issues).
+
+To troubleshoot just the command-line used to start the Minecraft server, set the environment variable `DEBUG_EXEC` to `true`.
+
+To troubleshoot any issues with memory allocation reported by the JVM, set the environment variable `DEBUG_MEMORY` to `true`.

Set `SYNC_SKIP_NEWER_IN_DESTINATION=false` if you want files from `/config` to take precedence over newer files in `/data/config`.
+
+By default, the [environment variable processing](#replacing-variables-inside-configs) is performed on synchronized files that match the expected suffixes in `REPLACE_ENV_SUFFIXES` (by default "yml,yaml,txt,cfg,conf,properties,hjson,json,tml,toml") and are not excluded by `REPLACE_ENV_VARIABLES_EXCLUDES` and `REPLACE_ENV_VARIABLES_EXCLUDE_PATHS`. This processing can be disabled by setting `REPLACE_ENV_DURING_SYNC` to `false`.
 
 If you want old mods/plugins to be removed before the content is brought over from those attach points, then add `-e REMOVE_OLD_MODS=TRUE`. You can fine tune the removal process by specifying 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 is 16) variable to only delete files up to a certain level.
 
 For example: `-e REMOVE_OLD_MODS=TRUE -e REMOVE_OLD_MODS_INCLUDE="*.jar" -e REMOVE_OLD_MODS_DEPTH=1` will remove all old jar files that are directly inside the `plugins/` or `mods/` directory.
 
-You can specify the destination of the files that are copied from `/mods` and `/config` by setting the `COPY_MODS_DEST` and `COPY_CONFIG_DEST`, where the default is `/data/mods` and `/data/config`. For example, `-v ./config:/config -e COPY_CONFIG_DEST=/data` will allow you to copy over files like `bukkit.yml` and so on directly into the server directory.
-
 These paths work 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.

+Instead of mounting the `/data` volume, you can instead specify the URL of a ZIP file containing an archived world.

+> **NOTE:** if running multiple containers be sure to either specify a different `-v` host directory for each
 `LEVEL` in use or don't use `-v` and the container's filesystem will keep things encapsulated.
 
-### Downloadable world
+> **INFO** Refer to the [data directory](#data-directory) section for a visual description of where the `$LEVEL` directory is situated.
-
-Instead of mounting the `/data` volume, you can instead specify the URL of a ZIP file containing an archived world. It will be searched for a file `level.dat` and the containing subdirectory moved to the directory named by `$LEVEL`. This means that most of the archived Minecraft worlds downloadable from the Internet will already be in the correct format.
-
-    docker run -d -e WORLD=http://www.example.com/worlds/MySave.zip ...
-
-**NOTE:** This URL must be accessible from inside the container. Therefore,
-you should use an IP address or a globally resolvable FQDN, or else the
-name of a linked container.
-
-**NOTE:** If the archive contains more than one `level.dat`, then the one to select can be picked with `WORLD_INDEX`, which defaults to 1.
-
-### Cloning world from a container path
-
-The `WORLD` option can also be used to reference a directory or zip file that will be used as a source to clone or unzip the world directory.
-
-For example, the following would initially clone the world's content
-from `/worlds/basic`. Also notice in the example that you can use a
-read-only volume attachment to ensure the clone source remains pristine.
-
-```
-docker run ... -v $HOME/worlds:/worlds:ro -e WORLD=/worlds/basic
-```
-
-### Overwrite world on start
-The world will only be downloaded or copied if it doesn't exist already. Set `FORCE_WORLD_COPY=TRUE` to force overwrite the world on every server start.
-
-### Downloadable mod/plugin pack for Forge, Bukkit, and Spigot Servers
-
-Like the `WORLD` option above, you can specify the URL or path of a "mod pack"
-to download and install into `mods` for Forge or `plugins` for Bukkit/Spigot.
-To use this option pass the environment variable `MODPACK`, such as
-
-    docker run -d -e MODPACK=http://www.example.com/mods/modpack.zip ...
-
-**NOTE:** The referenced URL must be a zip file with one or more jar files at the
-top level of the zip archive. Make sure the jars are compatible with the
-particular `TYPE` of server you are running.
-
-You may also download or copy over individual mods using the `MODS` environment variable. `MODS` contains a comma-separated list of
-- URL of a jar file
-- container path to a jar file
-- container path to a directory containing jar files
-
-    docker run -d -e MODS=https://www.example.com/mods/mod1.jar,/plugins/common,/plugins/special/mod2.jar ...
-
-### Remove old mods/plugins
-
-When the option above is specified (`MODPACK`) you can also instruct script to
-delete old mods/plugins prior to installing new ones. This behaviour is desirable
-in case you want to upgrade mods/plugins from downloaded zip file.
-To use this option pass the environment variable `REMOVE_OLD_MODS="TRUE"`, such as
-
-    docker run -d -e REMOVE_OLD_MODS="TRUE" -e MODPACK=http://www.example.com/mods/modpack.zip ...
-
-**WARNING:** All content of the `mods` or `plugins` directory will be deleted
-before unpacking new content from the MODPACK or MODS.

 ## Miscellaneous Options
 
+### Replacing variables inside configs
+
+Sometimes you have mods or plugins that require configuration information that is only available at runtime.
+For example if you need to configure a plugin to connect to a database,
+you don't want to include this information in your Git repository or Docker image.
+Or maybe you have some runtime information like the server name that needs to be set
+in your config files after the container starts.
+
+For those cases there is the option to replace defined variables inside your configs
+with environment variables defined at container runtime.
+
+When the environment variable `REPLACE_ENV_IN_PLACE` is set to `true` (the default), the startup script will go through all files inside the container's `/data` path and replace variables that match the container's environment variables. Variables can instead (or in addition to) be replaced in files sync'ed from `/plugins`, `/mods`, and `/config` by setting `REPLACE_ENV_DURING_SYNC` to `true` (defaults to `false`). 
+
+Variables that you want to replace need to be declared inside curly brackets and prefixed with a dollar sign, such as  `${CFG_YOUR_VARIABLE}`, which is same as many scripting languages.
+
+You can also change `REPLACE_ENV_VARIABLE_PREFIX`, which defaults to "CFG_", to limit which environment variables are allowed to be used. For example, with "CFG_" as the prefix, the variable `${CFG_DB_HOST}` would be subsituted, but not `${DB_HOST}`.
+
+If you want to use a file for value (like when use secrets) you can add suffix `_FILE` to your variable name.
+
+Variables will be replaced in files with the following extensions:
+`.yml`, `.yaml`, `.txt`, `.cfg`, `.conf`, `.properties`.
+
+Specific files can be excluded by listing their name (without path) in the variable `REPLACE_ENV_VARIABLES_EXCLUDES`.
+
+Paths can be excluded by listing them in the variable `REPLACE_ENV_VARIABLES_EXCLUDE_PATHS`. Path
+excludes are recursive. Here is an example:
+```
+REPLACE_ENV_VARIABLES_EXCLUDE_PATHS="/data/plugins/Essentials/userdata /data/plugins/MyPlugin"
+```
+
+Here is a full example where we want to replace values inside a `database.yml`.
+
+```yml
+
+---
+database:
+  host: ${CFG_DB_HOST}
+  name: ${CFG_DB_NAME}
+  password: ${CFG_DB_PASSWORD}
+```
+
+This is how your `docker-compose.yml` file could look like:
+
+```yml
+version: "3.8"
+# Other docker-compose examples in /examples
+
+services:
+  minecraft:
+    image: itzg/minecraft-server
+    ports:
+      - "25565:25565"
+    volumes:
+      - "mc:/data"
+    environment:
+      EULA: "TRUE"
+      ENABLE_RCON: "true"
+      RCON_PASSWORD: "testing"
+      RCON_PORT: 28016
+      # enable env variable replacement
+      REPLACE_ENV_VARIABLES: "TRUE"
+      # define an optional prefix for your env variables you want to replace
+      ENV_VARIABLE_PREFIX: "CFG_"
+      # and here are the actual variables
+      CFG_DB_HOST: "http://localhost:3306"
+      CFG_DB_NAME: "minecraft"
+      CFG_DB_PASSWORD_FILE: "/run/secrets/db_password"
+
+volumes:
+  mc:
+  rcon:
+
+secrets:
+  db_password:
+    file: ./db_password
+```
+
+### Patching existing files
+
+JSON path based patches can be applied to one or more existing files by setting the variable `PATCH_DEFINITIONS` to the path of a directory that contains one or more [patch definition json files](https://github.com/itzg/mc-image-helper#patchdefinition) or a [patch set json file](https://github.com/itzg/mc-image-helper#patchset).
+
+Variable placeholders in the patch values can be restricted by setting `REPLACE_ENV_VARIABLE_PREFIX`, which defaults to "CFG_".
+
+The following example shows a patch-set file were various fields in the `paper.yaml` configuration file can be modified and added:
+
+```json
+{
+  "patches": [
+    {
+      "file": "/data/paper.yml",
+      "ops": [
+        {
+          "$set": {
+            "path": "$.verbose",
+            "value": true
+          }
+        },
+        {
+          "$set": {
+            "path": "$.settings['velocity-support'].enabled",
+            "value": "${CFG_VELOCITY_ENABLED}",
+            "value-type": "bool"
+          }
+        },
+        {
+          "$put": {
+            "path": "$.settings",
+            "key": "my-test-setting",
+            "value": "testing"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+> **NOTES:** Only JSON and Yaml files can be patched at this time. TOML support is planned to be added next. Removal of comments and other cosmetic changes will occur when patched files are processed.
+
+### Running with a custom server JAR
+
+If you would like to run a custom server JAR, set `-e TYPE=CUSTOM` and pass the custom server
+JAR via `CUSTOM_SERVER`. It can either be a URL or a container path to an existing JAR file.
+
+If it is a URL, it will only be downloaded into the `/data` directory if it wasn't already. As
+such, if you need to upgrade or re-download the JAR, then you will need to stop the container,
+remove the file from the container's `/data` directory, and start again.
+
+### Force re-download of the server file
+
+For VANILLA, FORGE, BUKKIT, SPIGOT, PAPER, CURSEFORGE, SPONGEVANILLA server types, set
+`$FORCE_REDOWNLOAD` to some value (e.g. 'true) to force a re-download of the server file for
+the particular server type. by adding a `-e FORCE_REDOWNLOAD=true` to your command-line.
+
+For example, with PaperSpigot, it would look something like this:
+
+```
+docker run -d -v /path/on/host:/data \
+    -e TYPE=PAPER -e FORCE_REDOWNLOAD=true \
+    -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server

 **You must greatly increase or disable max-tick-time watchdog functionality.** 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 to a very large value or -1 to disable it entirely, which is highly recommended. That can be set with `MAX_TICK_TIME` as described in [the section below](#max-tick-time).
