 Arch Linux users can install the [`lscolors-git`][3] package from the AUR for easy
 integration with bash, csh, or zsh.
 
+## zsh integration with Zplugin
+There's a Zsh plugin manager `Zplugin` that nicely works with this repository
+– `dircolors` will be ran **only once on each update**. So `dircolors` will not
+read the `LS_COLORS` definitions and perform the computation each time a new
+shell is started, but **instead** only once per `trapd00r/LS_COLORS` install
+and per update (with `zplugin update trapd00r/LS_COLORS`) and only then
+generating the script `c.zsh` containing the `dircolors` output and after this
+just sourcing it when the shell starts, thus making the shell to startup faster:
+
+```
+zplugin ice atclone"dircolors -b LS_COLORS > c.zsh" atpull'%atclone' pick"c.zsh"
+zplugin load trapd00r/LS_COLORS
+```
+
 ## ZSH syntax highlighting
 [zsh-syntax-highlighting-filetypes][0] highlights file on the command-line in
 realtime, using these colors.
