 ## Fonts
 
-Depending on your configuration, you might need to install a Powerline font. Follow the
-[font installation guide](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions#step-2-install-a-powerline-font)
-from Powerlevel9k.
+Powerlevel10k doesn't require custom fonts but it can take advantage of them if they are available.
+Some of the style options in Powerlevel10k are available only when using
+[Nerd Fonts](https://github.com/ryanoasis/nerd-fonts).
+
+If you don't know which font to use, download
+[these 4 fonts](https://github.com/romkatv/dotfiles-public/tree/master/.local/share/fonts/NerdFonts)
+and install them. In most systems you can install fonts simply by clicking on the `ttf` files. Then
+change your terminal's font to `MesloLGS NF` (NF stands for Nerd Fonts).
+
+- **iTerm2**: Open *Preferences → Profiles → Text → Change Font*. Set *Font* to `MesloLGS NF`.
+- **GNOME**: Type this command:
+
+```zsh
+sudo apt install libglib2.0-bin
+gsettings set org.gnome.desktop.interface monospace-font-name 'MesloLGS NF 11'
+```
+
+- **Command Prompt** (the default terminal app) on Windows: Use
+  [this script](https://gist.github.com/romkatv/aa7a70fe656d8b655e3c324eb10f6a8b).
+- **Visual Studio Code** (builtin terminal): *Open File → Preferences → Settings*, enter
+  `terminal.integrated.fontFamily` in the search box and set the value to `MesloLGS NF`.
 
-[Lean](https://github.com/romkatv/powerlevel10k/blob/master/config/p10k-lean.zsh) config doesn't
-require custom fonts. It'll work even with regular system fonts. If you are having trouble with
-Powerline fonts, try this config.
