-# Nerd Fonts
-
-This is an archived font from the Nerd Fonts release v3.3.0.
-
-For more information see:
-* https://github.com/ryanoasis/nerd-fonts/
-* https://github.com/ryanoasis/nerd-fonts/releases/latest/
-
-# Hack
-
-A typeface designed for source code.
-
-For more information have a look at the upstream website: https://github.com/source-foundry/Hack
-
-Version: 3.003
-
-## 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)
-
-For more information see: [The FAQ](https://github.com/ryanoasis/nerd-fonts/wiki/FAQ-and-Troubleshooting#which-font)
