+# CLI Config
+
+CLI Config (`cli-config.json`) is an optional file
+which can be used to modify the UI aspects of the Pakku CLI.
+
+The `cli-config.json` must be located in the [Pakku directory (`.pakku`)](Pakku-Directory.md).
+The relative path from the `.minecraft` directory should be: `.pakku/cli-config.json`.
+
+## Properties
+
+`theme`
+: Can be `default` or `ascii`. (Defaults to `default` 😜.)
+: - The `default` theme uses [UTF-8](https://en.wikipedia.org/wiki/UTF-8) symbols
+which may not be properly rendered in some terminals.
+: - The `ascii` theme limits the characters to [ASCII](https://en.wikipedia.org/wiki/ASCII) only.
+
+`ansi_level`
+: Can be `none`, `ansi16`, `ansi256` or `truecolor`.
+(By default it is automatically detected based on your terminal/CMD.)
