The WebDAV module readme points to http://documentation.magnolia-cms.com/modules/webdav.html which does not yet exist.

The docs or readme should at least list which systems work and how to map what where.

Hint: you can map the resources using for instance the OSX finder (press apple-k) and enter http://localhost:8080/magnoliaAuthor/.webdav/resources.

Same for templates (http://localhost:8080/magnoliaAuthor/.webdav/templates)

Resources currently only supports js files and css (not images!)

Remember that changes to templates in the repository will need to be applied to all instances (author and public) AND if you want them to show up at all, the template in the repository needs to be "enabled" (check the little check box in the template dialog)
