To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. New users are also welcome to post any questions or concerns to the arrivals lounge. If you are familiar with Wikipedia, take a look over some of the differences here.
Please also have a look at the guidelines on avoiding the appearance of touting. Don't interpret this as impugning your motives: It's normal in most situations to state how close a hotel is to x, y and z. However, Wikivoyage is much more restrictive about this, so as to avoid having similar information in numerous hotel listings.
All the best,
