There's just one simple guideline - Your submission should educate the learners about the basics or advanced concepts of a particular topic holistically, not just a part of it. Think of it this way - would this resource be a good starting point if you are setting out to learn a programming language or design tool/thinking from scratch?
So, the following are good examples:
- Basics of Python
- From beginner to advanced in Photoshop
The following are bad examples:
- Building a simple login/logout system in PHP
- How to use Twitter OAuth
- How to use the 3d effect in Adobe Illustrator
Submitted tutorials are evaluated by the community moderators.
It can take up to 7 days to vet the submitted tutorial. You will be informed of approval or rejection via email notification.
In rare cases, when community moderators could not reach a consensus about the quality of submitted tutorial, it might be kept in a queue and would be revalidated after a few weeks. It will happen when your tutorial is recently launched, and no course/tutorial preview is available without signing up or paying.
