Wikivoyage:Cooperating with Wikipedia
Guide for Wikipedians 
We have a special Welcome, Wikipedians page to introduce our project to people familiar with Wikipedia.
Sharing content 
Am I free to take anything from Wikipedia and post it on Wikivoyage? 
Basically yes, but there are a few things you need to think about before you start re-using anything from Wikipedia:
- Wikivoyage is not a travel encyclopedia. This means that far from all information on Wikipedia fits Wikivoyage. Typical things you may use are different types of illustrations, history extracts for the "Understand" section in our articles (but then again: don't get tempted to post 250 kB of the entire history of any country or town!) or information about the climate of the place you're writing about.
- Wikivoyage is targeted towards printed versions. We want travellers on the road to be able to print out a copy of an article and use it. The print version comes first!
- Make sure you check what you post. As stated above, what's on Wikipedia might not fit on Wikivoyage. So, before you copy and paste it to Wikivoyage, read it through and see if the information really is useful for a traveller. When in doubt - leave it out.
How do I follow the copyleft license? 
If you post text from Wikipedia on Wikivoyage, you are required to post a specific template on the talk page of the guide on Wikivoyage. The template should go at the very top of the talk page and may not be removed (unless the Wikipedia content is removed from Wikivoyage, that is). Add the template according to the instructions here. This way, you attribute the contributors who participated to the work on Wikipedia. Please note that if you want to copy something from Wikipedia (in your language version) to Wikivoyage in the same language (if there is one), you have to create a template in the actual language. Use the template provided here and translate it.
Remember that Wikivoyage, even if it is a Wikimedia Foundation web site, also is a project wholly independent from Wikipedia, and one of our principal goals is to enrich the world through that ever elusive online original content. Copy-pasting blocks of text from Wikipedia is very much discouraged, and will often be reverted. The best use of text from Wikipedia (or any other source with a compatible Creative Commons license or Public Domain status) is when you are having a mental block and grab phrasing from elsewhere.
If you want to post a Wikipedia illustration of some kind in a Wikivoyage guide, you do not have to use the template. Instead, upload the illustration on Wikimedia Commons.
Links to Wikipedia 
- Main article: Links to Wikipedia
Linking to Wikipedia allows people to access encyclopedic information that doesn't fit into the framework of a travel guide. For example, the entry on the United Kingdom should have a thumbnail sketch of the country's history, but detailed information on Henry VIII is inappropriate. A link to Wikipedia's UK article would allow readers to find non-travel related information about their destination of choice, without stretching Wikivoyage beyond recognition into an "everything you need to know about everything" guide. However, don't use links as an excuse to be lazy. Wikivoyage entries should be useful and self-contained; links should provide additional information. Writing "Everything you need to know about France is here, except that there's a good bagel place in Lyon" is not helpful.
If there's a page on Wikipedia that covers the exact same subject as a page on Wikivoyage you can link to it.
On Wikivoyage, you can simply place:
near the end of the article, where article name is the name of the Wikipedia article you are linking to.
See the draft proposal Wikivoyage:Sister project links for more details.
Linking from Wikipedia 
- Main article: Links from Wikipedia
If there's a page on Wikipedia that covers the exact same subject as a page on Wikivoyage, you can link from it to Wikivoyage. On Wikipedia, you can simply follow the instructions in w:Template:Wikivoyage or in w:Template:Sister_project_links, to place a box with a link back to Wikivoyage from the Wikipedia article.
Links in Wikipedia not only assist readers to get directly to Wikivoyage, they also promote Wikivoyage by improving its ranking in search engines. When search engines index Wikipedia pages containing the Wikivoyage template, they see the direct link to the Wikivoyage article, not the template code.
Specific projects 
There are always various projects in the works at Wikipedia, similiar to Wikivoyage's concept of Expeditions. Some of these could be used by both Wikipedia and Wikivoyage. See, for example, the work being done on maps.
