+Commands:

+```
+
+## How it works:
+
+- Uses [dat-pinning-service-client](https://github.com/beakerbrowser/dat-pinning-service-client) to talk to pinning services that adhere to [DEP 0003](https://www.datprotocol.com/deps/0003-http-pinning-service-api/)
+- Can start a local pinning service called `dat-pin` using `dat-pin install-service` (uses [os-service](https://www.npmjs.com/package/os-service))
+- Runs on `127.0.0.1:3472`
+- Binds to port `3282` for interacting with the P2P network
+- The service uses [dat-librarian](https://www.npmjs.com/package/dat-librarian) to manage archives
+- The service acts as a discovery gateway for [discovery-swarm-stream](https://www.npmjs.com/package/discovery-swarm-stream)
