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. If you are familiar with Wikipedia, take a look over some of the differences here.
Thanks for asking about whether or how to start a new page. You'll want to look at Wikivoyage:How to start a new page and Wikivoyage:What is an article. If you have any questions after you look over those pages, you're welcome to ask them in a reply below.
Happy editing!
All the best,
