A Plymouth theme based on BGRT & Spinner themes, but featuring Xiaomi progress bar
To install, copy all files from master to /usr/share/plymouth/themes/bgrt-mi/ and run sudo plymouth-set-default-theme -R bgrt-mi.
Arch and Manjaro users might prefer to download PKGBUILD and plymouth-theme-bgrt-mi.install files and run makepkg -i in order to build a package.
This theme has Manjaro branding by default so Arch guys might prefer to do sudo cp /usr/share/plymouth/arch-logo.png /usr/share/plymouth/themes/bgrt-mi/watermark.png first.
Then issue sudo plymouth-set-default-theme -R bgrt-mi and you are good to go.
