+# Tiny FixedDecimal FFI Demo
+
+This example contains tooling to build a size-optimized binary using FixedDecimal and FixedDecimalFormatter in C over FFI.
+
+Prerequisites: `clang` and `lld` 14. `apt-get install clang lld` *might* work, but if you run into errors, refer to the following thread for tips:
