+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.

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.

 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.
+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`). 
 
-Optionally you can also define a prefix to only match predefined environment variables.
+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.
 
-`ENV_VARIABLE_PREFIX="CFG_"` <-- this is the default prefix
+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 use file for value (like when use secrets) you can add suffix `_FILE` to your variable name (in  run command).
