Our tool works on publicly visible MediaWiki installations, so if you haven't already installed MediaWiki do that first.
Now that you have a wiki, grab the url to a page on your wiki. It doesn't matter what page you pick, we'll fetch that URL and discover the location to your wiki's API ourselves.
Once we've found your wiki's API we'll try to automatically discover what type of server you're running, your script path, and any other technical information we need to help you configure your wiki.
We'll pick a default article path we think you might like. If it's wrong enter a new one and we'll update the config we give you.
We'll generate the complete server and MediaWiki configuration you need to setup short URLs, just follow the instructions and your wiki will be running with short URLs.
