Editing pages on Wikipedia can be done with or without an account on many pages. Some pages are, however, restricted from anonymous editing due to frequent vandalism or controversy. Some of these pages are locked entirely in extreme cases.

As for how to becoming a good contributor, Wikipedia has its own internal list of guidelines, summarizing over 200 pages of best practices that reflect its culture. Here are a few of the major categories with their most relevant and important points from that lengthy list:

 - Behavioral guidelines:
   - Assume good faith in others
   - Don't create conflicts of interest (such as self-promotion)
   - Don't spam to prove a point
 - Content guidelines:
   - Cite sources
   - External links should be relevant and of quality
   - Fringe theories should be covered only where their influence has been recognized by independent reliable sources
   - No plagiarism
 - Editing guidelines:
   - Be bold: fix problems, correct grammar, and add facts
   - Resolve ambiguities in language
   - Make articles as understandable as possible to the widest audience of readers
 - Notability guidelines:
   - Only subjects with significant outside attention warrant inclusion on Wikipedia
 - Style guidelines:
   - Wikipedia keeps its own style guidelines for pages, hew close to that when creating or editing content
   - Keep date and number formats consistent
   - Use clear, direct language

Following these internal guidelines will make your edits more compatible with Wikipedia's existing content, more academically valuable for readers and more helpful to the project in its goal of creating an effective and free online encyclopedia.
