Wikipedia has great resources for editing help!
Wikipedia's rules can be thought of as five pillars that show how the project works:
Wikipedia is an encyclopedia containing elements of general and specialized encyclopedias, almanacs, and gazetteers.
Wikipedia has a neutral point of view, which means we strive for articles that advocate no single point of view.
Wikipedia is free content that anyone may change.
Wikipedia has a code of conduct: Respect your fellow Wikipedians even when you may not agree with them.
