+# Colored man pages plugin
+
+This plugin adds colors to man pages.
+
+To use it, add `colored-man-pages` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... colored-man-pages)
+```
+
+It will also automatically colorize man pages displayed by `dman` or `debman`,
+from [`debian-goodies`](https://packages.debian.org/stable/debian-goodies).
+
+You can also try to color other pages by prefixing the respective command with `colored`:
+
+```zsh
+colored git help clone
+```
+
+## Customization
+
+The plugin declares global associative array `less_termcap`, which maps termcap capabilities to escape
+sequences for the `less` pager. This mapping can be further customized by the user after the plugin is
+loaded. Check out sources for more.
+
+For example: `less_termcap[md]` maps to `LESS_TERMCAP_md` which is the escape sequence that tells `less`
+how to print something in bold. It's currently shown in bold red, but if you want to change it, you
+can redefine `less_termcap[md]` in your zshrc file, after OMZ is sourced:
+
+```zsh
+less_termcap[md]="${fg_bold[blue]}" # this tells less to print bold text in bold blue
+```
