 The `configuration.py` module is responsible for loading the settings from `app_settings.json` (including loading and saving the JSON content), merging them with the rules from the selected preset file, and providing the base configuration via the `load_base_config()` function. Note that the old `config.py` file has been deleted.
 
 The `app_settings.json` file is structured into several key sections, including:
-*   `FILE_TYPE_DEFINITIONS`: Defines known file types (like different texture maps, models, etc.) and their properties. Each definition now includes a `"standard_type"` key for aliasing to a common type and a `"bit_depth_rule"` key specifying how to handle bit depth for this file type. The separate `MAP_BIT_DEPTH_RULES` section has been removed.
+*   `FILE_TYPE_DEFINITIONS`: Defines known file types (like different texture maps, models, etc.) and their properties. Each definition now includes a `"standard_type"` key for aliasing to a common type (e.g., "COL" for color maps, "NRM" for normal maps), an `"is_grayscale"` boolean property, and a `"bit_depth_rule"` key specifying how to handle bit depth for this file type. The separate `MAP_BIT_DEPTH_RULES` section has been removed. For users creating or editing presets, it's important to note that internal mapping rules (like `Map_type_Mapping.target_type` within a preset's `FileRule`) now directly use the main keys from these `FILE_TYPE_DEFINITIONS` (e.g., `"MAP_COL"`, `"MAP_RGH"`), not just the `standard_type` aliases.
 *   `ASSET_TYPE_DEFINITIONS`: Defines known asset types (like Surface, Model, Decal) and their properties.
 *   `MAP_MERGE_RULES`: Defines how multiple input maps can be merged into a single output map (e.g., combining Normal and Roughness into one).

+*   They also define how variants (like different resolutions or bit depths) are handled and how asset names and categories are determined from the source filename. When defining `map_type_mapping` rules within a preset, the `target_type` field must now use a valid key from the `FILE_TYPE_DEFINITIONS` in `config/app_settings.json` (e.g., `"MAP_AO"` instead of a custom alias like `"AO"`).
 
 When processing assets, you must specify which preset to use. The tool then loads the core settings from `config/app_settings.json` and merges them with the rules from the selected preset to determine how to process the input.
