+# Consumer Simulation E2E Test
+
+The files in this directory simulates a consumer of web services, using JSON RPC over IPFS. It starts a new IPFS node that connects to the ipfs-bch-wallet-service and exercises each JSON RPC endpoint.
+
+## Instructions
+
+Execute these steps in order to run the test:
+
+1. Run your local copy of ipfs-bch-wallet-service service provider.
+2. Update the [test-data.json](./test-data.json) file with the IPFS ID of the ipfs-bch-wallet-service.
+3. In another terminal, run the client simulation with `node client.e2e.js`
