-## Running a Forge Server
+### 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: "3.8"
+
+minecraft-server:
+  image: itzg/minecraft-server
+
+  ports:

+
+  environment:
+    EULA: "TRUE"
+
+  tty: true
+  stdin_open: true
+  restart: always
+```
+
+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.

+### Running a Forge Server
 
 Enable [Forge server](http://www.minecraftforge.net/wiki/) mode by adding a `-e TYPE=FORGE` to your command-line.
 
 The overall version is specified by `VERSION`, [as described in the section above](#versions) and will run the recommended Forge version by default. You can also choose to run a specific Forge version with `FORGEVERSION`, such as `-e FORGEVERSION=14.23.5.2854`.

         -e FORGE_INSTALLER=forge-1.11.2-13.20.0.2228-installer.jar ...

 the URL with `FORGE_INSTALLER_URL`, such as:

 In both of the cases above, there is no need for the `VERSION` or `FORGEVERSION` variables.
 
-### Managing mods
-
-In order to manage mods, you have two options:
-
-1. [Attach a host directory to the /data path](#attaching-data-directory-to-host-filesystem) and manage the contents of the `mods` subdirectory
-
-2. Using a mods-mount
-
-If the container paths `/mods` and/or `/config` exist, such as by attaching a docker volume or host path, then any files in either of these directories will be copied over to the respective `/data` subdirectory before starting Minecraft. 
-
-If you want old mods to be removed as the `/mods` content is updated, 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.
-
-> NOTE: If a file was updated in the destination path and is newer than the source file from `/config`, then it will not be overwritten.

+**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

+### 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.

+**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:

-
-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.

-
-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.
 
 ```

 ```
 
-## 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:
-
-```
-minecraft-server:
-  image: itzg/minecraft-server
-
-  ports:
-    - "25565:25565"
-
-  environment:
-    EULA: "TRUE"
-
-  tty: true
-  stdin_open: true
-  restart: always
-```
-
-and in the same directory as that file run
-
-    docker-compose up -d

 **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
-
-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 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 individual mods using the `MODS` environment variable and supplying the URL
-to the jar files. Multiple mods/plugins should be comma separated.
-
-    docker run -d -e MODS=https://www.example.com/mods/mod1.jar,https://www.example.com/mods/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.
+
+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}
+```
+
+This is how your `docker-compose.yml` file could look like:
+
+```yml

+
+### 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
+```
