 This runs the test suite against a fresh download of Neo4j.  
 Or `npm test` if you already have a running version of a compatible Neo4j server.
 
+### Testing on windows
+Running tests on windows requires PhantomJS installed and its bin folder added in windows system variable `Path`.  
+To run the same test suite, run `.\runTest.ps1` instead in powershell with admin right.  
+The admin right is required to start/stop Neo4j properly as a system service.  
+While there is no need to grab admin right if you are running tests against an existing Neo4j server using `npm test`.

 ## A note on numbers and the Integer type
 For this driver to fully map to the Neo4j type system handling of 64-bits Integers is needed.  
 Javascript can saftely represent numbers between `-(2`<sup>`53`</sup>` - 1)` and `(2`<sup>`53`</sup>` - 1)`.
