How do you delete a question

If you want to edit your question, visit the question you asked and click on the Edit option under it, which is a blue text I think. But, make sure that no one has reported your question or no one is writing an answer to that question. If someone starts to write the answer, you can’t edit the question.

Hope this helps :)
