So, where do we possibly begin? Let's start with [Five pillars]: five concepts that inform everything else. Here's a super-fast overview:
"Wikipedia is an encyclopedia" — Makes sense, right? It's not a textbook, it's not a directory, but an encyclopedia.
"Wikipedia is written from a neutral point of view" — Basically, Wikipedia should be descriptive, not opinionated.
"Wikipedia is free content that anyone can use, edit, and distribute" — In a sense, no one owns Wikipedia. We'll explain more later.
"Editors should treat each other with respect and civility" — If Wikipedia is going to work, everyone needs to get along.
"Wikipedia has no firm rules" — Rules are meant to support the encyclopedia, and can change over time.
Got all that? Don't worry: we'll explain each in more detail ahead.
