+
+**Resources:**
+* https://www.nerdfonts.com/font-downloads
+* https://github.com/ryanoasis/nerd-fonts/releases/download/v3.0.0/NerdFontsSymbolsOnly.zip
+
+## How to generate
+
+Copy all the required base fonts into this directory and run:
+
+```sh
+./generate-fonts.py
+```
+or
+```sh
+fontforge -script generate-fonts.py
+```
+
