Welcome to the documentation for the Awesome window manager. Below you find an
overview of the individual parts which links to the full documentation.
If you are a new user, you may want to read @{07-my-first-awesome.md} to get
started. In @{05-awesomerc.md}, the default configuration is explained.
If you already used awesome in the past, @{89-NEWS.md} and @{17-porting-tips.md}
should be useful for you.
