+## Recommended palettes to use
+
+These are a few palettes that have been generalized to be used in almost any map, usually to provide variation to terrain:
+
+| Palette                          | Usage
+| ---                              | ---
+| `parametrized_walls_palette`     | For having randomized inner and outer walls
+| `parametrized_fences_palette`    | For having randomized fences
+| `parametrized_linoleum_palette`  | For having randomized linoleum colors
+| `parametrized_carpets_palette`   | For having randomized carpet colors
+
+
+These can all be found within [common_parameters.json](/data/json/mapgen_palettes/common_parameters.json)
+
+The following are recommended for use when making houses or similar domestic environments:
+
+| Palette                          | Usage
+| ---                              | ---
+| [`domestic_general_and_variant_palette`](/data/json/mapgen_palettes/house_general_palette.json)     | A palette which has most of the things needed for houses with additional palettes available within the file
+| [`construction_general_palette`](/data/json/mapgen_palettes/construction.json)    | A palette for buildings that are under construction, for a more concrete example of using this palette, look at [house_02](/data/json/mapgen/house/house02.json)
+| [`commercial`](/data/json/mapgen_palettes/commercial.json)  | For having randomized fridges/freezers **You will still need to add the parameters to your own symbols**
+| Any in [basement.json](/data/json/mapgen_palettes/basement.json)   | Palettes for usage within basements
+| [`roof_palette`](/data/json/mapgen_palettes/roof_palette.json)   | Palette that is be used in every roof
+
+There are many more within [`/data/json/mapgen_palettes`](/data/json/mapgen_palettes/) but these are the most important ones and will be used in many buildings.

 # Using `update_mapgen`
 
 **update_mapgen** is a variant of normal JSON mapgen.  Instead of creating a new overmap tile, it
