 [![Build Status](https://dev.azure.com/home-assistant/Hass.io/_apis/build/status/addons?branchName=master)](https://dev.azure.com/home-assistant/Hass.io/_build/latest?definitionId=7&branchName=master)
 
-# Hass.io Addons repository
+Add-ons for the Hass.io ecosystem, allow you to extend the functionality
+around your Home Assistant setup. These add-on can consist of an application
+that Home Assistant can integrate with (e.g., a MQTT broker or database server)
+or allow access to your Home Assistant configuration (e.g., via Samba or using
+the Configurator).
 
-https://home-assistant.io/hassio
+Add-ons can be installed and configured via the Home Assistant frontend on
+systems that have installed Hass.io.
 
-### Best practice
-- Make a bash script called `run.sh` it will parse and prepare the env
-- If you have a special configuration file move it to `/etc` or modify the default configuration file at its origin place
