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.
If you have other questions, please ask in a reply below. You asked how you can help. I would say you could always start the way I did years ago when I first found this site: Check on the articles about the place where you live and places you've visited and see whether any important or interesting information was left out, needs updating or is represented inaccurately, or whether the article simply needs copy editing.
All the best,
Thank you for contributing to Wikivoyage! Unfortunately, your contributions are extremely similar to those of a persistent vandal on Wikivoyage who likes to create empty articles about very small places, and as a result they have been reverted as a precaution - see this thread for details. If you feel that your edits have been incorrectly identified and would like to contribute to Wikivoyage constructively, there are some suggestions that you might find useful at Wikivoyage:Quick contribution guide, and you can also review Wikivoyage:What is an article? for details on what subjects get their own articles. If you have questions you can ask them on this talk page or in the pub. -- Ryan • (talk) • 22:10, 27 January 2017 (UTC)
