+# SmartOS Web Interface
+
+SmartOS now has a web based user interface available. This UI is most directly
+simply exposing SmartOS primitives via a web interface for the purposes of
+managing instances and aims to make simpler tasks much more approachable for new
+users, as well as make more complex tasks easier for advanced users.
+
+Note that while we have tried to make sure SmartOS features are represented in
+the Web UI, not all features are yet exposed. And due to the nature of SmartOS
+being much more free form than Triton, it's possible that you may have a
+configuration on an instance or image that causes errors in the UI.
+[Please report these][i] errors so that we may correct this.
+
+[i]: https://github.com/TritonDataCenter/smartos-ui/issues
+
+## Installation
+
+To install the web interface, download and run the installer.
+
+```sh
+curl -O https://us-central.manta.mnx.io/Joyent_Dev/public/SmartOS/ui-installer.sh
+bash ./ui-installer.sh
+```
+
+Or, the quick and dirty way:
+
+<!-- markdownlint-disable line-length -->
+
+```sh
+curl https://us-central.manta.mnx.io/Joyent_Dev/public/SmartOS/ui-installer.sh | bash
+```
+<!-- markdownlint-enable line-length -->
+
+## Accessing the Web UI
+
+The UI is available on port 4443. The installer will print out the URL
+by IP. If you are link-local to your SmartOS host you can also use the
+multicast DNS name. E.g.: `https://192.168.122.184:4443` or
+`https://my-smartos-host.local:4443`.
+
+The login for the Web UI is the root user and password of the system.
+This would be the same credentials used to log in via ssh or the console.
+
+The SSL certificate is automatically generated and stored in `/usbkey/tls`. This
+may be replaced with a custom certificate if you choose.
+
+## The `uiadm` command
+
+The `uiadm` command can be used to upgrade or uninstall the Web UI. It uses the
+following subcommands.
+
+<!-- markdownlint-disable line-length -->
+
+| command                   | action                                                                                                  |
+| ------------------------- | ------------------------------------------------------------------------------------------------------- |
+| `uiadm avail`             | List available installation candidates. Only versions newer than currently installed will be displayed. |
+| `uiadm install <version>` | Install the specified version. You can also use the keyword `latest`.                                   |
+| `uiadm install latest`    | Install the latest version.                                                                             |
+| `uiadm info`              | Display information about the current installation, including URL.                                      |
+| `uiadm remove`            | Completely uninstall the Web UI.                                                                        |

+
+## UI Tour
+
+The UI has the following tabs.
+
+* Dashboard
+* Instances
+* Images
+* Global Zone Config
+
+### Dashboard
+
+This page shows a summary of the overall system, including the number of
+instances and estimated available provisioning capacity.
+
+In the future this may include management of the PI or zpool, or the ability
+to reboot the entire server.
+
+### Instances
+
+This page allows management of existing instances. You can view the details and
+perform actions such as start, stop, or destroy. If the instance uses static
+IPs, the IP information will also be displayed.
+
+In the future, you will be able to update instance properties.
+
+#### Creating instances
+
+To create a new instance click the **Create** button. After selecting an image
+you may choose an appropriate instance brand and fill in additional details
+using the guided form.
+
+On the **Additional Properties** tab you can supply a JSON object that will
+be merged with properties from the guided form. You may also choose a merging
+strategy, whether the form or the JSON will take precedence if there are
+duplicate keys.
+
+Finally, you can preview the JSON payload on the **Final Properties** tab
+before provisioning. The Web UI will validate the JSON payload before
+provisioning to let you know about any errors.
+
+### Images
+
+This page allows you to view, import, or remove images.
+
+Images can only be removed if there are zero instances that depend on it.
+
+### Global Zone Config
+
+This page displays the global zone config file (`/usbkey/config`) as key value
+pairs.
+
+In the future you will be able to edit properties here.
