 ## `cuprate-benchmark-lib`
+This crate is the glue between
+[`cuprate-benchmark`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/bin)
+and all the benchmark crates.
+
+It defines the [`cuprate_benchmark_lib::Benchmark`] trait,
+which is the behavior of all benchmarks.
+
+See the [`cuprate-benchmark-example`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/example)
+crate to see an example implementation of this trait.
+
+After implementing this trait, a few steps must
+be done such that the `cuprate-benchmark` binary
+can actually run your benchmark crate; see the
+[`Benchmarking` section in the Architecture book](https://architecture.cuprate.org/benchmarking/intro.html)
+to see how to do this.
