-
-## 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
-BARBUK_GITLAB_CHAR='  '
-BARBUK_BITBUCKET_CHAR='  '
-BARBUK_GITHUB_CHAR='  '
-BARBUK_GIT_DEFAULT_CHAR='  '
-BARBUK_GIT_BRANCH_ICON=''
-BARBUK_HG_CHAR='☿ '
-BARBUK_SVN_CHAR='⑆ '
-BARBUK_EXIT_CODE_ICON=' '
-BARBUK_PYTHON_VENV_CHAR=' '
-```
-
-### Customize glyphs
-
-Define your custom glyphs before sourcing bash-it:
-
-```bash
-export BARBUK_GITHUB_CHAR='•'
-source "$BASH_IT"/bash_it.sh
-```
-
-## SSH prompt
-
-### Usage
-
-When using a ssh session, the theme will display `user@hostname`.
-You can disable this information with `BARBUK_SSH_INFO`.
-
-The hostname is displayed in the FQDN format by default. You
-can use the short hostname format with `BARBUK_HOST_INFO`.
-
-```bash
-# short or long
-export BARBUK_HOST_INFO=short
-# true or false
-export BARBUK_SSH_INFO=false
-source "$BASH_IT"/bash_it.sh
-```
-
-### Keep theme with sudoer
-
-If you want the theme to persist using `sudo -s` in a ssh session, you need to configure sudo to keep the `HOME` and `SSH_CONNECTION` environment variables.
-
-`HOME` contains the path to the home directory of the current user. Keeping it will allow to use your user dotfiles when elevating privileges.
-
-Keeping `SSH_CONNECTION` env is necessary for ssh detection in the theme.
-
-Please refer to the following documentation for more information:
- -  [sudo manual](https://www.sudo.ws/man/1.8.13/sudoers.man.html) for `env_keep` configuration
- -  [openssh manual](https://linux.die.net/man/1/ssh) for information about `SSH_CONNECTION` environment
-
-```bash
-cat << EOF > /etc/sudoers.d/keepenv
-Defaults env_keep += HOME
-Defaults env_keep += SSH_CONNECTION
-EOF
-chmod 400 /etc/sudoers.d/keepenv
-```
