 # XOA
 
+The fastest way to install Xen Orchestra is to use our Appliance. You can [download it from here](https://xen-orchestra.com/) (fill the form and click on "Try Now"). Basically, it's a Debian VM with all the stuff needed to run Xen Orchestra, no more, no less.
+
+Once you've got it, you can import it with `xe vm-import filename=xoa_version_number.xva` or via XenCenter.
+
+After the VM is imported, you just need to start it with a `xe vm-start vm=XOA` or with XenCenter.
+
+XOA is in **DHCP** by default, so if you need to configure the IP, you need to edit `/etc/network/interfaces` as explained in the [Debian documentation](https://wiki.debian.org/NetworkConfiguration#Configuring_the_interface_manually). You can access the VM console through XenCenter or using VNC through a SSH tunnel.
+
+Xen Orchestra is now accessible in your browser on ` http://your-vm-ip` or in HTTPS on the same URL.
+
+## Default admin account
+
+Default user is **admin@admin.net** with **admin** as a password.
+
+## XOA credentials
+
+By default, system/SSH user and password are **root**/**xoa**. Be smart and change the root password as soon as possible!
+
+## Restart XOA
+
+You can restart XOA by going in XOA on SSH (or console) and type `systemctl restart xo-server.service`.
+
+To check the status of `xo-server`, use `systemctl status xo-server.service`, it should display something like that:
+
+```
+xo-server.service - XO Server
+   Loaded: loaded (/etc/systemd/system/xo-server.service; enabled)
