+The Honeywell Lyric component integrates the Lyric thermostat platform into Home Assistant.
+
+## Setup
+
+To set up this component, you will need to set up a developer account with Honeywell:
+
+1. Go to the [developer site](https://developer.honeywellhome.com) and register with an account.
+1. Next, create a [new app](https://developer.honeywellhome.com/user/me/apps/add) via the `My Apps` section.
+   1. App Name: You can use any name here.
+   1. Callback URL: This needs to be the URL of your Home Assistant instance + `/auth/external/callback`. For example: `http://192.168.1.123:8123/auth/external/callback`.
+
+Once your app is created, copy the `Consumer Key` and `Consumer Secret`. These will be your `client_id` and `client_secret` to add to your configuration:
+
+```yaml
+# Example configuration.yaml entry
+lyric:
+  client_id: MY_CONSUMER_KEY
+  client_secret: MY_CONSUMER_SECRET
+```
+
+You can then add the integration in the frontend.
+
+## Configuration
+
+Menu: **Configuration** -> **Integrations**.
+
+Click on the `+` sign to add an integration and click on **Honeywell Lyric**.
+Log in with your Honeywell Lyric account and agree to the terms. The Honeywell Lyric integration will then be available.
