 + It is advisible to check the script first before running it.
 + You need `bash` to run it.
-+ The script will fail if you have multiple profile directory! Make sure you only have one!
-+ If you have a current chrome folder in your profile directory, the script will make a backup.
-+ If the installation script is not working, a PR is welcome!
++ If you have an existing chrome folder, the script will make a backup of it in your profile directory.
++ If the installation script is not working, feel free to submit an issue or a pull request.

 ### If you're using Windows or macOS and something's wrong
 
-1. I only have Archlinux, so I cannot guarantee that it will work on Windows 10 and macOS without a problem. A feedback and a PR is absolutely welcome! All you can do or try is to install the theme, then change the value of `--bf-moz-appearance` variable to either `-moz-win-glass` if windows and `-moz-mac-vibrancy-dark` if macOS. Still, do no expect that it will work without a problem. The platforms are untested!

 1. You can change the colors in `userChrome.css`.
 2. The transparency is only applied to `Dark` and `Light` colorschemes. `No transparency == No blur`.
 
+### How can I set or change the colors for the Default colorscheme?
+
+1. The default colorscheme are from Firefox and it uses the system colors. Although I only tried and tested it with `GTK3`, it should work with any platforms or environment as long as Firefox can detect your system colors. So all you can do is to switch theme to change its colorscheme.
