 Normally you will have to push your changes before running the scripts. This
 approach makes it easier to track back what exactly was tested by the scripts.
 
 In the scripts there are variables to tell **git** where to get the source
-code from, user name, **branch**, etc. The variable are:
+code from (the repository URL), user name to be used by git (from your git
