+# Ground, but written in C this time
+
+This repo houses the new Ground interpreter, which will replace the old C++ interpreter.
+
+Features of this interpreter:
+
+* Written in C instead of C++
+* Somewhat organised and readable codebase
+* Not super buggy (yet)
+* Uses standard, portable C*
+
+Now that Ground's features have mostly been finalised, this interpreter can be built with care to many features not initially planned, like functions and data structures
+
+*so far, only tested on Linux, but hopefully should work on other platforms as well 
+
