 # 🔧 Configuration
 
-The configuration is meant to be used by modpack developers, hence no in-game (client-side) settings are available.
+The configuration is meant to be used by modpack developers, hence no in-game (client-side) settings are available. It is a server-side only configuration, can be found at `config/dungeon_difficulty_v2.json`.
 
-Server side configuration can be found at `config/dungeon_difficulty.json`.
+Regex fields in the configuration are interpreted as fully featured regex. If you are unfamiliar with regex, first make sure to learn about it (start for example [here](https://www.youtube.com/watch?v=sXQxhojSdZM)). It is recommended to test out your regex patterns using tool: [regex101.com](https://regex101.com)
 
-Use the following command to refresh the config while in game: `/dungeon_difficulty_config_reload`
+Editing the config usually involves the steps below:
+1. Open the config file
+2. Set `allow_customization` to `true`, so your config doesn't get overridden with defaults at launch
+3. Define difficulty types (in `difficulty_types` array), which describe scaling of entities of looted items
+4. Assign difficulty to locations referencing a difficulty type by its name, and an arbitrary level. These can be dimension by regex, biomes by regex and structures by specific structure ID.
 
-Config file is parsed into `Config` object. You can find it [here](./src/main/java/net/dungeon_difficulty/config/Config.java).
+Check out the default configuration to see specific examples.
 
-Config file is **sanitized** upon reloading, meaning every non parsable data is removed.
