 # profiles plugin
 
 This plugin allows you to create separate configuration files for zsh based
-on a domain of your host.
+on your long hostname (including the domain).
 
-It takes your `HOST` and looks for files named according to the domain parts 
-in `$ZSH_CUSTOM/profiles/` directory.
+To use it, add profiles to the plugins array of your zshrc file:
 
-For example, for `HOST=my.domain.com`, it will try to load the following files:
+```sh
+plugins=(... profiles)
+```
+
+It takes your `$HOST` variable and looks for files named according to the
+domain parts in `$ZSH_CUSTOM/profiles/` directory.
+
+For example, for `HOST=host.domain.com`, it will try to load the following files,
+in this order:
 
 ```text
-$ZSH_CUSTOM/profiles/my.domain.com
-$ZSH_CUSTOM/profiles/domain.com
 $ZSH_CUSTOM/profiles/com
+$ZSH_CUSTOM/profiles/domain.com
+$ZSH_CUSTOM/profiles/host.domain.com
 ```
 
-To use it, add profiles to the plugins array of your zshrc file:
-
-```sh
-plugins=(... profiles)
-```
+This means that if there are conflicting settings on those files, the one to take
+precedence will be the last applied, i.e. the one in host.domain.com.
