-Pulsar is a hobby PL, which, for fun, I am implementing both software and hardware backends.
-Currently, I am working toward implementing such a hardware backend via the [calyx] infrastructure.
+Pulsar is a programming language for building hardware accelerators.
+In what exactly? I'm not sure yet.
 
-The WIP syntax is a very blatant clone of Swift's with some modifications.
+As of right now, I'm using Swift's syntax for that nice syntax highlighting:
 ```swift
 func increment(x: Int) -> Int {
     return x + 1
