 Two configuration parameters will be asked: the **main domain name** and the **administration password**.
 
+**Attention**: The post-installation may break your system if you interrupt it, be aware.

 ### Main domain
 
 This is the first domain name linked to your YunoHost server, but also the one which will be used by your server's users to access the **authentication portal**. It will thus be **visible by everyone**, choose it wisely.
