## Installing a third-party add-on repository

Home Assistant allows anyone to create an add-on repository to share their own add-ons with the community.

{% warning %}
Home Assistant cannot guarantee the quality or security of third-party add-ons. Use at your own risk.
{% endwarning %}

To add an add-on repository, follow these steps:

1. Copy the URL of the repository.
   - The URL is the git repository clone URL (on GitHub, use the Code button and copy the HTTPS URL).
   - This documentation uses an example add-on repository. It is not practically useful but follows the same steps. 
   - If you are interested in add-on development, refer to our [add-on development documentation](https://developers.home-assistant.io/docs/add-ons).

        ```
2. Go to {% my supervisor title="**Settings** > **Add-ons**" %} and select **Add-on store**.

### Troubleshooting: Repository is not showing up

If you have added an add-on repository, but it's not showing up, make sure to refresh your browser. If it still doesn't show up, the add-on repository may contain invalid configuration data.

1. Go to {% my logs title="**Settings** > **System** > **Logs**" %} and select Supervisor in the top right corner to get the Supervisor log.
   - It should tell you what went wrong.
2. Report this information to the add-on repository author.
