+`antcc` is a C compiler using its own custom backend. Currently still in a
+experimental stage.
+
+# Supported targets
+
+- For now just x86-64 POSIX (Sys-V + ELF). Only tested on linux so far.
+
+# Building
+
+```
+make   # outputs ./antcc executable
+# or
+make opt #compile with optimizations
+# or
+make dbg #compile with UBsan and Asan
+```
+
+
+# Usage
+
+The driver is still incomplete but it mimics that of compilers like gcc.
+`antcc` compiles translation units to object files directly, but the driver
+will invoke an external linker command to output an executable if `-c` isn't passed.
