-# Welcome to the Asahi Linux documentation!
+Welcome to the Asahi Linux documentation! Here, you will find documentation on the
+Apple Silicon platform as implemented on Mac computers with M-series SoCs. We aim
+to document the platform in a way that is useful for everyone, however our focus is
+supporting third-party operating systems, particularly Linux.
 
-We are just getting started.
+We also have documentation on the various pieces of software required to properly
+support this platform, such as m1n1 and U-Boot. Documentation for software that we
+have created (such as m1n1) aims to be as complete as possible. Documentation for
+external projects (such as U-Boot) is limited to how that software is used on the
+Apple Silicon platform.
+
+## Who this documentation is for
+- Operating system and kernel developers looking to implement support for Apple Silicon
+- Folks interested in hacking on and reverse engineering the Apple Silicon platform
+- End users looking for guides and information on supported features
+- Anyone interested in the Asahi Linux project looking for more information
 
 Questions? Please check out the [FAQ](project/faq.md) first!
