 # Aro
 A C compiler with the goal of providing fast compilation and low memory usage with good diagnostics.
 
-Right now preprocessing and parsing is mostly done but anything beyond that is missing.
+Currently it can preprocess, parse and semantically analyze ~75% of standard C17 with 
+work still being needed to support all of the usual extensions.
+
+Future plans for the project include making it the C backend of Zig's `translate-c` feature and
+making it an optional C frontend for the self-hosted Zig compiler.
