+
+The Nightscout integration allows you to view your CGM data from [Nightscout](http://www.nightscout.info/) in Home Assistant.
+
+## Configuration
+
+To add `Nightscout` to your installation, go to **Configuration** >> **Integrations** in the UI, click the button with `+` sign and from the list of integrations select **Nightscout**.
+
+Then just input your server URL in the `Host` field. For example:
+
+- `https://localhost:5423`
+- `https://your-app-name.herokuapp.com`
+
+### Sensor
+
+If you have a sensor session running, and once you have enabled the Nightscout integration, you should see a `sensor.blood_glucose` entity.
+
+It's icon changes to indicate the direction or trend, of the glucose readings.
+The state is the last reading from Nightscout, and you can see other information about the reading in the sensor's attributes.
+
+### Example Automation
