 ## About
 rjp (rexy's json parser) is a very simplistic json parser written in C. There is absolutely no reason for this to exist but I felt like making it :P
 
-Currently only installs 2 files: librjp.a and rjp.h
+Also includes rjp++, a C++ wrapper around the core rjp library. Building of this library can be disabled with cmake and is currently impossible to build since I haven't released librexy to my public gitlab yet. Remind me to update this readme when I do release that library.
 
 ## Building
-Building will produce a static library by default but can be configured to build a shared library.
