+# `rpc-compat` Simulator
+
+The `rpc-compat` simulator runs a suite of [conformance tests][tests] against
+all available clients. Its primary objective is to ensure clients return the
+same values over JSON-RPC so that they may be treated as a black box by
+downstream tooling such as wallets and dapps.
+
+## Getting Started
+
+To run the simulator locally, first build `hive`.
+
+```
+go build
+```
+
+Then start the simulator.
+
+```
+./hive --sim ethereum/rpc-compat --client go-ethereum,besu,nethermind
+```
+
+### Running local tests
+
+To run a set of local tests instead of the standard conformance test suite,
+place the `tests` directory into the `rpc-compat` simulator directory and
+uncomment the lines in the `Dockerfile` associated with adding the directory to
+the build process and then comment out the `git clone` command. Now, the above
+`hive` command can be executed again.
+
+## Test Generation
+
+Please see the `execution-apis` testing [documentation][tests].
+
