-## notes
+## configure
+
+**tracking**
+
+xpm keeps track of installed/uninstalled packages (only what you've requested for install, not including its dependencies) in `~/.local/share/xpm/installed.txt`.
+
+This behaviour can be disabled by setting *XPM_NOTRACK* to 1, either in your environment.
+
+**hooks**
+
+xpm supports 'hooks' (inspired by git-hooks). A 'hook' is a script that gets executed *after* running the specified command.
+
+All you need to do is add the script file to execute in `~/.config/xpm/hooks` and make sure it's executable.
 
-- Add hooking (á la githooks)
+This is useful if you install package outside of the package manager that require a seperate command to execute, or if you want to add additional behaviour to the default xpm commands.
