 ## Installation
 
+### Development Environment
+
+A development environment will allow you modify the code on-the-fly and contribute to the code base of this repository. [PM2](https://www.npmjs.com/package/pm2) is recommended for running this code base as an IPFS Circuit Relay.
+
+- [Video: Installing ipfs-service-provider](https://youtu.be/Z0NsboIVN44)
+- [Step-by-step installation instructions](https://gist.github.com/christroutner/3304a71d4c12a3a3e1664a438f64d9d0)
+
 ```bash
 git clone https://github.com/Permissionless-Software-Foundation/ipfs-bch-wallet-service
 cd ipfs-bch-wallet-service
+./install-mongo.sh
 npm install
-npm start
+cd shell-scripts 
+./ipfs-bch-wallet-service.sh
 ```
 
+### Production Environment
+
+The [docker](./production/docker) directory contains a Dockerfile for building a production deployment. However, there is currently [a bug](https://github.com/Permissionless-Software-Foundation/ipfs-service-provider/issues/38) preventing the Docker container from being used as a Circuit Relay.
+
+```
+docker-compose build --no-cache
+docker-compose up -d
+```
+
+### Operation Notes
+
+- There is a memory leak in the version of js-ipfs. The app is currently configured to shut down every 8 hours to flush memory. It relies on a process manager like pm2, Docker, or systemd to restart the app after it shuts down, in order to ensure continuous operation.

 ## Structure
 
 The file layout of this repository differs from the koa-api-boilerplate. Instead, it follows the file layout of [Clean Architecture](troutsblog.com/blog/clean-architecture).
