+# Nerd Fonts
+
+This is an archived font from the Nerd Fonts release v3.4.0.
+
+For more information see:
+* https://github.com/ryanoasis/nerd-fonts/
+* https://github.com/ryanoasis/nerd-fonts/releases/latest/
+
+# Go Mono
+
+**Go** is a font created for the Go project.
+
+https://go.dev/blog/go-fonts
+
+For more information have a look at the upstream website: https://go.googlesource.com/image/
+
+Download link https://go.googlesource.com/image/+/master/font/gofont/ttfs/
+
+Version: 2.010
+
+## Which font?
+
+### TL;DR
+
+* Pick your font family:
+  * If you are limited to monospaced fonts (because of your terminal, etc) then pick a font with `Nerd Font Mono` (or `NFM`).
+  * If you want to have bigger icons (usually around 1.5 normal letters wide) pick a font without `Mono` i.e. `Nerd Font` (or `NF`). Most terminals support this, but ymmv.
+  * If you work in a proportional context (GUI elements or edit a presentation etc) pick a font with `Nerd Font Propo` (or `NFP`).
+
+### Ligatures
+
+Ligatures are generally preserved in the patched fonts.
+Nerd Fonts `v2.0.0` had no ligatures in the `Nerd Font Mono` fonts, this has been dropped with `v2.1.0`.
+If you have a ligature-aware terminal and don't want ligatures you can (usually) disable them in the terminal settings.
+
+### Explanation
+
+Once you narrow down your font choice of family (`Droid Sans`, `Inconsolata`, etc) and style (`bold`, `italic`, etc) you have 2 main choices:
+
+#### `Option 1: Download already patched font`
+
+ * For a stable version download a font package from the [release page](https://github.com/ryanoasis/nerd-fonts/releases)
+ * Or download the development version from the folders here
+
+#### `Option 2: Patch your own font`
+
+ * Patch your own variations with the various options provided by the font patcher (i.e. not include all symbols for smaller font size)
+
