+# Sharing via ngrok
+
+Vagrant share can be driven using ngrok from the underlying transport
+by supplying the `--driver ngrok` flag to `vagrant share`.
+
+The ngrok driver is not enabled by default. When starting the Vagrant
+share, ngrok must be specified as the driver. Users connecting to
+the share must also specify the ngrok driver to make a proper connection.
+
+
+## Sharing
+
+Starting a Vagrant share using the ngrok driver is very similar to the
+default Vagrant share command. The only addition it requires is the
+`--driver ngrok` flag:
+
+```
+$ vagrant share --driver ngrok
+```
+
+By default this will create a public HTTP endpoint
+connected to the shared VM via an ngrok process. When only HTTP is being
+shared, no connection is required from the remote side. All that is required
+is the public ngrok URL.
+
+### SSH
+
+To share an ssh connection to the shared VM the `--ssh` flag must be provided.
+Vagrant share will then create a small utility VM to enable the share with
+remote users. Once the setup is complete, a name will be assigned to the
+utility VM that remote users can reach using the `vagrant connect` command.
+
+### Full Share
+
+To enable full remote access to the shared VM the `--full` flag must be provided.
+This will enable remote users connecting to the local share full access to all
+forwarded ports defined by the shared VM Vagrantfile.
+
+## Connecting
+
+Much like the `vagrant share` command, when connecting to a Vagrant share
+that was created using the ngrok driver, the `--driver ngrok` flag must
+be provided:
+
+```
+$ vagrant connect --driver ngrok share_name
+```
+
+## ngrok configuration
+
+The current user's ngrok configuration file is used by default when
+tunnels are created for Vagrant share. While specific customization
+to the ngrok configuration is not yet supported, the feature is being
+actively worked on and will be available in the future.
