+# Redline Theme
+
+changed up the powerline base a little.
+
+It plays nicest with  this font: [DroidSansMonoForPowerline](https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/DroidSansMono)
+
+Read the [powerline theme documentation](https://github.com/Bash-it/bash-it/blob/master/themes/powerline/README.md)
+
+
+## added
+* hostname
+* distro logo
+
+## changed
+* sudo credential check
+* required font
+* some icons
+
+Works real good like with:
+```bash
+## set the theme
+export BASH_IT_THEME='redline'
+
+# Set this to false to turn off version control status checking within the prompt for all themes
+export SCM_CHECK=true
+
+## Set Xterm/screen/Tmux title with only a short hostname.
+export SHORT_HOSTNAME=$(hostname -s)
+
+## enable sudo prompt
+export POWERLINE_PROMPT_USER_INFO_MODE="sudo"
+
+## prompt part string
+export POWERLINE_PROMPT="python_venv user_info hostname cwd scm"
+
+```
+
+## enable your distro logo with
+```bash
+export POWERLINE_PROMPT_DISTRO_LOGO="yes"
+```
+
