+# Rust based Benchmarks
+
+## Building
+
+Build with
+
+```
+cargo run --package build_benches
+```
+
+This builds the benchmark `.wasm` files for all the Rust based benchmarks
+such as `tiny_keccak`, `reverse_complement` and `regex_redux` with proper
+optimizations and stores the results in their respective directories.
+
+## Usage
+
+Use this script whenever a benchmark has changed or when a new Rust, LLVM or `wasm-opt`
+version has been released.
