There has been some interest in having a wiki for documenting the XML, python, etc., but so far nobody has put one up. So.... http://www.civ4wiki.com/wiki/index.php/Main_Page If there's enough interest to get this rolling, this could turn in to a really good resource for understanding/documenting the game files. Adding a new article to a wiki is easy, simply append the article name to the wiki URL and it will take you to a blank article where you can begin editing. For example, the Main_Page article uses this URL: hxxp://www.civ4wiki.com/wiki/index.php/Main_Page So if you wanted to start a new article on some random topic you would go to: hxxp://www.civ4wiki.com/wiki/index.php/SomeRandomTopic You can begin editing from there. Each article has 4 tabs along the top of the page. article discussion edit history The article tab lets you read the latest version of the article. The discussion tab is where people can talk about article content and modification. Edit is where you go to update the page. History contains a list of every article revision ever made, and you can do version comparisons. If the article hasn't been created then history will be missing. Editing can be tricky if you don't know the markup that mediawiki uses to display the page. The page can simply be text, but if you want to add headers and a table of contents you'll have to read up on page markup: http://meta.wikimedia.org/wiki/Help:Editing If you've never seen a wiki in action before, head on over to wikipedia.org Edit: The new domain is up and running.
