How do I share info about Unity?

As I work with Unity I discovered some things that can be useful. Is it okay to write them down? or is there a special place where I can write them down?

You can share your results/scripts in the community wiki or on the forums. This website (Unity Answers) is a place to ask (and answer) questions, not to share knowledge (although you can share your knowledge if it answers a specific question asked by another user).

You can also write a blog about your scripts, projects.
