 > **Recreating the semantic map style.** The per-class semantic masks are parsed from a
-> *custom-styled* Google map in which each land-cover class is rendered in a fixed colour. You
-> must recreate this map style in your own Google Cloud account and set its map-style ID above.
-> The exact class→colour mapping is defined in `CLASS_COLORS_HEX` at the top of
-> `Obtain_corresponding_map_signed.py` — reproduce those colours in your style.
+> *custom-styled* Google map in which each land-cover class is rendered in a fixed colour. We
+> provide the exact style definition at [`docs/semantic_map_style.json`](docs/semantic_map_style.json).
+> To reproduce it, open the Google Cloud console, go to **Map Styles → Create style → JSON tab →
+> Upload JSON File**, upload this file, and save. The style is built on the *light* base map,
+> which supplies the default water / vegetation / land colours, while building, railway and road
+> surfaces are recoloured explicitly. Set the resulting **Map ID** as `GOOGLE_MAPS_STYLE_MAP_ID`.
+> The class→colour mapping consumed by the parser is in `CLASS_COLORS_HEX` at the top of
+> `Obtain_corresponding_map_signed.py`.
 
 > By using these scripts you are making **live calls to the Google Maps Platform under your own
 > account**, and you are responsible for complying with the
