You might want to start with the Wikipedia Tutorial, it has loads of very helpful information, and links to more in-depth information if you get the "WikiBug" like many of us do. Finally, please do your best to always fill in the edit summary field.
I'm including some useful links to help you get started. If you have any questions, feel free to head over to my Talk page and ask!
