What are the guidelines for writing good questions?

We want Unity Answers to become a comprehensive database of questions and answers related to Unity. When you ask your questions, it can be helpful to keep a few things in mind:

Some reasons for getting a post rejected:

There exists duplicate questions with answers if you were to do a search, either on Answers or on the Forum or on Unity's tutorials

Your question isn't specific enough: **asking for a script**, asking multiple questions in one post or asking a question that could be either subjective or require extensive discussion

Your question is about very basic issues, that can be learned just by searching in google or in multiple basic tutorials for begginers
