 ## Installing Zaf
 You need to be root and you must have curl installed on your system. Depending on your system, github certificates may not be available so you have to use *-k* option for curl (insecure). Default installation type is silent. So there will be no questions and everything will be autodetected. This simple command should be used on most systems:
 ```
-curl -k https://raw.githubusercontent.com/limosek/zaf/master/install.sh | sh
+curl -k https://raw.githubusercontent.com/limosek/zaf/1.1/install.sh | sh
 ```

+curl -k https://raw.githubusercontent.com/limosek/zaf/1.1/install.sh | \
    sh -s {auto|interactive|debug-auto|debug-interactive} [Agent-Options] [Zaf-Options]
 ```
 or use git version:
 ```
-git clone https://github.com/limosek/zaf.git; cd zaf; git checkout master
