+## Steps to reproduce

+<!--
+A description of how to trigger this bug.
 
-**To Reproduce**
-Steps to reproduce the behavior:
 1. Go to '...'
 2. Click on '....'
 3. Scroll down to '....'
 4. See error
 
-**Expected behavior**
-A clear and concise description of what you expected to happen.
+If it's possible follow these guidelines for a good sample and I will most likely look at the issue sooner:
 
-**Screenshots**
-If applicable, add screenshots to help explain your problem.
+- Post a full GitHub repository. Not a zip file, half baked snippet etc. If GitHub is new to you consider it a great learning opportunity and chance to get involved.
+- The repository should have just ONE step max for me to get running, and that is "Restore NuGet Packages". If there are any other missing dependencies, or new features I will most likely move on to another issue.
+- I'm not trying to be awkward. I'm just busy and I'm helping a lot of people, not just you, so help me out and I will help you out.
