Remember when editing, the fundamental principles by which Wikipedia operates are in the form of five "pillars":


Blue pillar (1: Encyclopedia) Wikipedia is an encyclopedia that uses content that should be verifiable with citations to reliable sources. Our editors' personal experiences, interpretations, or opinions do not belong here.
 
Green pillar (2: NPOV) Wikipedia has a neutral point of view, which means we strive for articles that advocate no single point of view.
 
Yellow pillar (3: Free) Wikipedia is free content that anyone can edit and distribute. Respect copyright laws.
 
Orange pillar (4: Code of conduct and etiquette) Wikipedians should interact in a respectful and civil manner: Respect and be polite to your fellow Wikipedians, even when you disagree.
 
Red pillar (5: Ignore all rules) Wikipedia does not have firm rules besides the five general principles presented here. Be bold in updating articles and do not worry about making mistakes.
