+# Home Assistant Cast
+
+Home Assistant Cast is made up of two separate applications:
+
+- Chromecast receiver application that can connect to Home Assistant and display relevant information.
+- Launcher website that allows users to authorize with their Home Assistant installation and launch the receiver app on their Chromecast.
+
+## Development
+
+- Run `script/develop_cast` to launch the Cast receiver dev server. Keep this running.
+- Navigate to http://localhost:8080 to start the launcher
+- Debug the receiver running on the Chromecast via [chrome://inspect/#devices](chrome://inspect/#devices)
+
+## Setting up development environment
+
+### Registering development cast app
+
+- Go to https://cast.google.com/publish and enroll your account for the Google Cast SDK (costs \$5)
+- Register your Chromecast as a testing device by entering the serial
+- Add new application -> Custom Receiver
+  - Name: Home Assistant Dev
+  - Receiver Application URL: http://IP-OF-DEV-MACHINE:8080/receiver.html
+  - Guest Mode: off
+  - Google Case for Audio: off
+
+### Setting dev variables
+
+Open `src/cast/dev_const.ts` and change `CAST_DEV_APP_ID` to the ID of the app you just created. And set the `CAST_DEV_HASS_URL` to the url of you development machine.
+
+### Changing configuration
+
+In `configuration.yaml`, configure CORS for the HTTP integration:
+
+```yaml
+http:
+  cors_allowed_origins:
+    - https://cast.home-assistant.io
+    - http://IP-OF-DEV-MACHINE:8080
+```
+
+## Running development
+
+```bash
+cd cast
+script/develop_cast
+```
+
+The launcher application will be accessible at [http://localhost:8080](http://localhost:8080) and the receiver application will be accessible at [http://localhost:8080/receiver.html](http://localhost:8080/receiver.html) (but only works if accessed by a Chromecast).
+
+### Developing cast widgets in HA ui
+
+If your work involves interaction with the Cast parts from the normal Home Assistant UI, you will need to have that development script running too (`script/develop`).
+
+### Developing the cast demo
+
+The cast demo is triggered from the Home Assistant demo. To work on that, you will also need to run the development script for the demo (`script/develop_demo`).

+        <p>
+          The Chromecast only works with websites served over HTTPS. This means
+          that the Home Assistant Cast app that runs on your Chromecast is
+          served over HTTPS. Websites served over HTTPS are restricted on what
+          content can be accessed on websites served over HTTP. This is called
+          mixed active content (<a

+        <p>
+          You're currently looking at the Home Assistant Cast launcher
+          application. This is a standalone application to launch Home Assistant
+          Cast on your Chromecast. Because Chromecasts do not allow us to log in
+          to Home Assistant, we need to supply authentication to it from the
+          launcher. This authentication is obtained when you authorize your
+          instance. Your authentication credentials will remain in your browser
+          and on your Cast device.
+        </p>
+        <p>
+          Your authentication credentials or Home Assistant url are never sent
+          to the Cloud. You can validate this behavior in
+          <a
+            href="https://github.com/home-assistant/home-assistant-polymer/tree/dev/cast"
+            target="_blank"

+        </p>
+        <p>
+          The launcher application exists to make it possible to use Home
+          Assistant Cast with older versions of Home Assistant.
+        </p>
+        <p>
+          Starting with Home Assistant 0.97, Home Assistant Cast is also built
+          into the Lovelace UI as a special entities card row. Since the
+          Lovelace UI already has authentication, you will be able to start
+          casting right away.
