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.

- Hi! On the license front, because of the license which Wikivoyage uses, all text/images/maps etc have to be either owned by the contributer or a compatible copyright... Unfortunately, the Google map license isn't compatible. However, have a look at the Wikimedia Commons because they sometimes have maps and photos we can use. Ones we can use are licensed under Creative Commons Share Alike, usually shortened to CCbySA or something similar.
