+Tool makes some checks and offers options:
+
+1. Autoinstall
+ - Installs all dependencies (necessary packages and Xen-Orchestra itself)
+ - Packages listed in the end of this README
+
+2. Update / Install without dependencies
+ - Installs Xen-Orchestra from latest sources (doesn't install any packages)
+
+3. Deploy container
+ - Offers options to build container locally or pull from dockerhub
+
+notes:
+
+ - If you choose to install with option 2, you need to take care that required packages are already installed
+ - You can change xo-server and xo-web git branch by editing xo-install.sh scripts $BRANCH variable
 
 ### docker
 You can also build the docker image locally if you wish or pull it from [docker hub](https://hub.docker.com/r/ronivay/xen-orchestra/) without using the script.
