                                                                                              Bridge is a client made for interacting with Azimuth. It's the recommended way to receive, send, and manage your Urbit identity, and it's by far the easiest way to generate the keyfile required to boot your ship. Most Bridge functions are accessed by "logging in" to an identity's ownership address or one of its proxy addresses. It's accessed at bridge.urbit.org.

                                                                                              Below are some important functions of Bridge.
