If you're using visual edit mode you highlight the text that you want to be the section heading, and at the top of the edit bar there is a dropdown box, click the dropdown box, choose Heading 2 to create a main section header.

You may want to create a sandbox to test your edits before you publish them to main articles if you are unsure. To do that, click this link: User:Alduin1996/Sandbox. A new sandbox that you can edit will be created and you can freely make edits to that page to experiment and test your editing.
