 ## Instructions
 
 ### Base logos
-Base logos should be supplied either by adding png files to [src/logogen/base/](base/),
-or by adding a logo component to [src/config/token_data.py](../config/token_data.py).
+Base logos for token `TOK` should be supplied either by adding `TOK.png` to [src/logogen/base/](base/),
+or by adding a `"logo"` entry to the appropriate block for `TOK` in [src/config/token_data.py](../config/token_data.py).
 If both are present, we'll use the one in [src/logogen/base/](base/),
 
 ### Generating new logos
+Run:
 ```
-npm run genlogos
+npm run gen-logos
+```
+
+This won't write over any existing images in [assets](../../assets].  To overwrite the existing assets:
+```
+npm run gen-logos-overwrite
 ```
 
 ### Linking to logos
 ```
 https://raw.githubusercontent.com/certusone/wormhole-token-list/main/assets/CAKE_wh.png
-```
+```
+
+## Styling
+
+A few style choices are included (with examples):
+
+thick_gray (default):
+
+![CAKE](examples/CAKE_wh_thick_gray.png)
+![UST](examples/UST_wh_thick_gray.png)
+
+thin_gray:
+
+![CAKE](examples/CAKE_wh_thin_gray.png)
+![UST](examples/UST_wh_thin_gray.png)
+
+color:
+
+![CAKE](examples/CAKE_wh_color.png)
+![UST](examples/UST_wh_color.png)
+
+barecolor:
+
+![CAKE](examples/CAKE_wh_barecolor.png)
+![UST](examples/UST_wh_barecolor.png)
+
+These variants are in [src/logogen/components](components/).
+
+To generate all the outputs with a different style from the default, run:
+```
+python3 gen_logos.py --overwrite --style STYLE
+```
+
+To update the default style, copy one of them to [src/logogen/components/wormhole.png](components/wormhole.png).
