+Read these guidelines. They are relatively simple and will allow me to help you better:
+
+1. Produce a simple, short, compilable test case that reproduces your problem.
+2. Make a descriptive title that summarises the bug as a whole.
+3. Explain the bug in as much detail as you can in the body of the issue. 
+4. Include Compiler/IDE (Visual Studio, XCode...), Build and Deployment System, Language (C++, Objective-C++), and any special defines you have set.
+
+If you want to request a feature:
+
+1. Produce any relevant imaginary code that illustrates what you would like or desired behavior.
+2. Include a description and title of what you would like.
+3. Annotate and describe the behavior through comments, asserts or just a small write up.
+
+Thanks for helping sol grow!
