+
+## About
+
+You can use this add-on to check whether your configuration files are valid against the
+new version of Home Assistant before you actually update your Home Assistant
+installation. This add-on will help you avoid errors due to breaking changes,
+resulting in a smooth update.
+
+## Installation
+
+The installation of this add-on is straightforward and easy to do.
+
+1. Navigate in your Home Assistant frontend to **Hass.io** -> **Add-on Store**.
+2. Find the "Check Home Assistant configuration" add-on and click it.
+3. Click on the "INSTALL" button.
+
+## How to use
+
+In the configuration section, set the version you want to check your configuration
+against. In case you'd like to check your configuration against the latest version of
+Home Assistant, just leave `latest`, which is already there as the default.
+
+1. Start the add-on.
+2. Have some patience and wait a couple of minutes.
+3. Check the add-on log output to see the result.
+
+If the log ends with `Configuration check finished - no error found! :)`,
+it means the check against your configuration passes on the specified
+Home Assistant version.
+
+## Configuration
+
+Add-on configuration:
+
+```json
+{
+  "version": "latest"
+}
+```
+
+### Option: `version` (required)
+
+The version of Home Assistant that want to check your configuration against.
+
+Setting this option to `latest` will result in checking your configuration
+against the latest stable release of Home Assistant.
+
+## Known issues and limitations
+
+- Currently, this add-on only support checking against Home Assistant >= 0.94
+  or less 0.91.
