* --- 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. * If you do not have a domain name, or if you want to use the YunoHost's DynDNS service, choose a sub-domain of **.nohost.me** or **.noho.st** (i.e. `homersimpson.nohost.me`). The domain will be configured automatically and you won't need any further configuration step. * If you do know what **DNS** is, you probably want to configure your own domain name here. In this case, please refer to the [yunohost.org/dns](/dns) page for more informations. ### Administration password This password will be used to access to your server's [administration interface](/admin). You would also use it to connect via **SSH** or **SFTP**. In general terms, this is your **system's key**, [choose it carefully](http://www.wikihow.com/Choose-a-Secure-Password). ### And after ? Once the post-installation finished, check if you can access to your server with your web-browser. If it is not the case, a few more configuration steps may be required.
