+Hey there and thank you for using PowerMock
+
+Please read the following tips before filing an issue:
+
+Is this something you can debug and fix?
+-------------------------------------------------------
+
+Can you see anything in the logs? Can you debug why this happens? **Send a pull request**! Bug fixes and documentation fixes are very welcome.
+
+
+Is this question about PowerMock usage?
+---------------------------------------
+
+The better way to ask question:
+
+* The mailing-list : https://groups.google.com/forum/#!forum/powermock / powermock@googlegroups.com
+* [Stackoverflow](http://stackoverflow.com/questions/tagged/powermock) with the tag 'powermock'. (Make sure you **include a short code snippet to demonstrate the problem** and if you have an exception then make sure **include stack trace**.)
+
+None of the above, want to create a GitHub issue
+------------------------------------------------------------------
+
+In order to help us to clarify issue can you answer the following question:
+
+What steps will reproduce the problem?
+What is the expected output?
+What do you see instead?
+What version of the product are you using?
+On what operating system?
