+# Installation guide on Debian
+
+Vous disposez de deux moyens pour installer YunoHost:
+You have two ways to install Yunohost:
+
+1. [From an USB key or a CD-ROM](#/install)
+2. With the install script on an existing Debian (bellow guide)
+
+### Pre-requisite
+A box, a VPS, or a dedicated server:
+
+* with Debian 7 (Wheezy, Raspbian, Cubian, etc.) installed
+* Connected to Internet
+* root access ou sudoer via SSH
+
+### Installation
+
+1. Connect to your debian system trought ssh
+```bash
+ssh root@monserveur.org
+```
+
+2. Install git
+```bash
+apt-get install git
+```
+
+3. Clone the Yonuhost install script repository
+```bash
+git clone https://github.com/YunoHost/install_script /tmp/install_script
+```
+
+4. Execute the install script
+```bash
+cd /tmp/install_script && ./install_yunohostv2
+```
+
+### Post-install
+
+Once the install finished, the script will ask you two parameters to procede the post-install:
+
+1. **domain name**: Please choose the domain name wich will point to your Yunohost IP. You can choose to use a subdomain of **nohost.me** or **noho.st**, in that case the DNS configuration will be automatic, you will just have to wait three min to the end of the post-install. Or you can use your own [well configured domain name](#/dns)
+
+2. **administrator password**: this is the password to administer you yunohost install, **choose it strong** and don't share it, without it you can loose your system.
+
+after the post-install script you will be able to access to your administration [web interface](#/admin) **https://your-domain.org/ynhadmin** or to amdinister your yunohost via the command-line interface called "[moulinette](#/moulinette)".
