+# Understand
+
+Before we install anything, it is helpful to understand what the Cloudron is and what exactly it is that you are installing.
+
+The Cloudron intends to make self-hosting effortless. It takes care of everything - updates, backups, firewall, dns setup,
+certificate management, just about everything. Once you install it on your server, you will never have to ssh into it again. There is a web interface to manage the users and apps on the server.
+
+This approach to self-hosting means that the Cloudron takes complete ownership of your server and
+you should not use your server for anything other than what is allowed using the web interface. For example, 
+currently the Cloudron is based on  Ubunutu 16. When Ubuntu 18 is released, Cloudron will help you migrate your
+apps and data from 16 to 18 easily. Anything you run or install on the server beside the Cloudron will be lost
+after an update. If you want to run anything on your server, it's best to make it a Cloudron app. This way the app 
+will persist across updates.
