Welcome to Wikipedia!
We're glad you wish to help develop Wikipedia, and we hope you enjoy participating in this virtual community. Linked below are some brief introductions containing all the basics you need to use, comment on, and edit Wikipedia.
As a new editor, also known as a contributor, you may feel a little overwhelmed by the sheer size and scope of Wikipedia. Don't worry if you don't understand everything at first, as it is acceptable to use common sense as you go about editing. We encourage you to be bold in a fair and accurate manner, with a straightforward, just-the-facts style.
The contributing to Wikipedia page provides information, links, videos and other resources on the basics needed to edit Wikipedia. The five pillars is a popular summary of the most pertinent Wikipedia principles. The community portal is a central location to find collaborations, tasks, and news about Wikipedia. If you somehow do get stuck, there are volunteers available to answer your questions; see asking for help for more information.
