 ## About
 
-I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now.
+*I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now.*
 
-I've grown tired of cutesy and condescending software that doesn't take itself or the user seriously. This is my effort to bring back the feeling of computing I once knew.
+Serenity is a love letter to '90s user interfaces, with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
 
-Roughly speaking, the goal here is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s \*nix. This is a system by me, for me, based on the things I like.

+If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)
