 The entry point for an `automerge-repo` based application is to create a [`Repo`](https://automerge.org/automerge-repo/classes/_automerge_automerge_repo.Repo.html), passing it some form of [`StorageAdapter`](https://automerge.org/automerge-repo/classes/_automerge_automerge_repo.StorageAdapter.html) - which knows how to save data locally - and zero or more [`NetworkAdapter`](https://automerge.org/automerge-repo/classes/_automerge_automerge_repo.NetworkAdapter.html)s, which know how to talk to other peers running `automerge-repo`.
