+### 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

+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`.

+### Downloadable mod/plugin pack for Forge, Bukkit, and Spigot Servers

-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.
+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

-For those cases there is the option to replace defined variables inside your configs
-with environment variables defined at container runtime.
+    docker run -d -e MODPACK=http://www.example.com/mods/modpack.zip ...

-If you set the enviroment variable `REPLACE_ENV_VARIABLES` to `TRUE` the startup script
-will go thru all files inside your `/data` volume and replace variables that match your
-defined environment variables. Variables that you want to replace need to be wrapped
-inside `${YOUR_VARIABLE}` curly brackets and prefixed with a dollar sign. This is the regular
-syntax for enviromment variables inside strings or config files.
+**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.

-Optionally you can also define a prefix to only match predefined environment variables.
+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

+### Remove old mods/plugins

-There are some limitations to what characters you can use.
+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

-| Type  | Allowed Characters  |

-`.yml`, `.yaml`, `.txt`, `.cfg`, `.conf`, `.properties`.
+**WARNING:** All content of the `mods` or `plugins` directory will be deleted
+before unpacking new content from the MODPACK or MODS.

-Specific files can be excluded by listing their name (without path) in the variable `REPLACE_ENV_VARIABLES_EXCLUDES`.
+## Working with world data

-Paths can be excluded by listing them in the variable `REPLACE_ENV_VARIABLES_EXCLUDE_PATHS`. Path

+### Downloadable world

-Here is a full example where we want to replace values inside a `database.yml`.
+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.

-```yml

---
-database:
-  host: ${CFG_DB_HOST}

-  password: ${CFG_DB_PASSWORD}
-```
+**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.

-This is how your `docker-compose.yml` file could look like:
+**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.

-If you would like to run a custom server JAR, set `-e TYPE=CUSTOM` and pass the custom server

-
-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:
+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.

 ## 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.
+
+If you set the enviroment variable `REPLACE_ENV_VARIABLES` to `TRUE` the startup script
+will go thru all files inside your `/data` volume and replace variables that match your
+defined environment variables. Variables that you want to replace need to be wrapped
+inside `${YOUR_VARIABLE}` curly brackets and prefixed with a dollar sign. This is the regular
+syntax for enviromment variables inside strings or config files.
+
+Optionally you can also define a prefix to only match predefined environment variables.
+
+`ENV_VARIABLE_PREFIX="CFG_"` <-- this is the default prefix
+
+If you want use file for value (like when use secrets) you can add suffix `_FILE` to your variable name (in  run command).
+
+There are some limitations to what characters you can use.
+
+| Type  | Allowed Characters  |
+| ----- | ------------------- |
+| Name  | `0-9a-zA-Z_-`       |
+| Value | `0-9a-zA-Z_-:/=?.+` |
+
+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}
+```

+### 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).
