+## 2.1 - Font
+
+The font we use in neovim is one from the [nerd]() font collection. Those fonts contain special characters used as an icon in NeoVim. "SauceCodePro NF" is a derivation of the "SourceCodePro" font.

+`lua/roka/core/options.lua`
+```lua
+vim.opt.guifont = { "SauceCodePro NF:h11:#e-subpixelantialias:#h-none" }
+```
+
+## 2.2 - Icons
+
+The various icons can be used by many plugins, example _nvim-tree_ or _lualine_.
