There is no documentation at all

Hello,

have you read README.txt? You can find how you install this module as well but you're right, there is no INSTALLATION.txt or something like this so I'll create one and better documentation.

Fixed in http://drupalcode.org/project/mediawiki_api.git/commit/a93fbed

INSTALL.txt instructructs the following:

4. Enter your MediaWiki API file URL, e.g. http://mediawiki.org/w/api.php

For me this does not work. If I select the newly created MediaWiki input format, the node renders empty. Totally empty, not text and no formating.

So please document what has to be done to use this module.

I've installed the D7 branch of this module to check out whether it is in any way incompatible with the freelinking module.

However, I am stuck at step for of INSTALL.txt, which says:

4. Enter your MediaWiki API file URL, e.g. http://mediawiki.org/w/api.php

Where do I enter it?

There seems to be no configuration page for the D7 branch, so it is far from obvious how one does this.

When you have created your new input format, e.g. "MediaWiki", you will find this setting at ./admin/config/content/formats/mediawiki. See screenshot.

Thanks for the head's up. Do not make any difference regarding the incompatibility between this module and the freelinking module.
