 ### Proxy Backend Mode
 
 Without specifying a _backend mode_, the `zrok share` command will assume that you're trying to share a `proxy` resource. A `proxy` resource is usually some private HTTP/HTTPS endpoint (like a development server, or a private application) running in your local environment. Usually such an endpoint would have no inbound connectivity except for however it is reachable from your local environment. It might be running on `localhost`, or only listening on a private LAN segment behind a firewall.

 In summary, `zrok` lets you easily and securely share resources with both general internet users (through _public_ sharing) and also with other `zrok` users (through _private_ sharing).
