 ```
 
+**Title options**
 
+- `theme_title_display_process`. By default theme doesn't show current process name in terminal title. If you want to show it, just set to `yes`.
+- `theme_title_display_path`. Use `no` to hide current working directory from title.
+- `theme_title_use_abbreviated_path`. Default is `yes`. This means your home directory will be displayed as `~` and `/usr/local` as `/u/local`. Set it to `no` if you prefer full paths in title.
+
+**Prompt options**
+- `theme_display_ruby`. Use `no` to completely hide all information about Ruby version. By default Ruby version displayed if there is the difference from default settings.
