+## Branches
+This code repository was refactored from CommonJS format to ECMA Script Modules (ESM) format because js-ipfs made the same change, and this repository depends heavily on that one. A CommonJS format version of this code repository is maintained in the [`cjs` branch](https://github.com/Permissionless-Software-Foundation/ipfs-service-provider/tree/cjs). This is useful for projects that can not make use of ESM yet, like [Electron.js](https://www.electronjs.org/) and [P2WDB](https://p2wdb.com).

 ## Circuit Relay
 
 This 'production' environment for this boilerplate sets up a series of Docker containers, orchestrated with Docker Compose. This boilerplate code can be run without modification, in order to set up a [Circuit Relay](https://docs.libp2p.io/concepts/circuit-relay/) and support the PSF network. You can get paid a [bounty](https://github.com/Permissionless-Software-Foundation/bounties) for doing so, in PSF tokens. See the section below on setting up a Production Docker Container.
