How to create simple HTML5 based forum


I am new in this forum and I’d like to know the faster way to build a simple question and answer forum for app users so any user can ask a question then “Send” it and then the other app users can see the question, answer it and see the other users’ answers and so on.
If you know any examples, ready to use extras or plugins, please provide me. I prefer to use HTML5 and JavaScript to create this simple question and answer forum.

Thank & Best Regards
