 This is a censorship-resistant, IPFS-based microservice that provides access for wallets to access the Bitcoin Cash (BCH) blockchain. It leverages [bch-js](https://github.com/Permissionless-Software-Foundation/bch-js).
 
+- [Decentralized Blockchain Service Providers](https://youtu.be/m_33rRXEats) YouTube video demos this software.
+- [JSON RPC and REST API Documentation](https://ipfs-bch-wallet-service.fullstack.cash/)
+
 ## About This Repository
 
 This repository is forked from the [ipfs-service-provider](https://github.com/Permissionless-Software-Foundation/ipfs-service-provider) repository. That code has been customized to provide BCH blockchain access for wallets. This server-side node.js app provides both REST API over HTTP and JSON RPC over IPFS endpoints for wallets to access the blockchain through.
 
 As part of the end-to-end testing, a virtual client can be started that will interrogate every endpoint provided by this API server. This client can be forked by developers to write their own apps that use this IPFS-based service.
 
+## Roadmap
+
+This repository is one step in a longer path. Here are the major milestones of this path:
+
+- Add wallet-based calls to ipfs-bch-wallet-service (this repository).
+- Create a miniature version of bch-js that makes calls over JSON RPC (bch-js-ipfs).
+- Given a variable, minimal-slp-wallet could call bch-js or bch-js-ipfs for network calls.
+- Fork slp-cli-wallet and add `daemon` feature to spin up IPFS node and work with bch-js-ipfs.

+
+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`
