+# Bluejay

+
+Bluejay is a preemptive kernel for x86. It is inspired by modern day
+UNIX-like systems and 80's Lisp machines. The goal is to create a
+fully usable kernel and graphical Lisp environment.
+
+While Bluejay is inspired by both UNIX and Lisp machines, it seeks to
+replicate neither. No attempt is made to conform to POSIX or even
+follow UNIX conventions. However, the "UNIX philosophy" of doing one
+thing and doing it well is certainly a consideration.
