+## Fonts and glyphs
+
+A font with SCM glyphs is required to display the default tool/host logos.
+You can use a font from https://www.nerdfonts.com/ or patch your own font with the tool
+provided by https://github.com/ryanoasis/nerd-fonts.
+
+You can also override the default variables if you want to use different glyphs or standard ASCII characters.
+
+### Default theme glyphs
+
+```bash
+SCM_GIT_CHAR_GITLAB='  '
+SCM_GIT_CHAR_BITBUCKET='  '
+SCM_GIT_CHAR_GITHUB='  '
+SCM_GIT_CHAR_DEFAULT='  '
+SCM_GIT_CHAR_ICON_BRANCH=''
+EXIT_CODE_ICON=' '
+```
+
+### Customize glyphs
+
+Define your custom glyphs before sourcing bash-it:
+
+```bash
+SCM_GIT_CHAR_GITHUB='•'
+source "$BASH_IT"/bash_it.sh
+```
+
