Please point to initial documentation in project page.

Nancy, the module is really, really basic, but I suppose I could make improvements to the documentation both in the d.org handbooks and in the README.txt. What kind of things are/were you expecting to see?

Absolutely. Path redirect is very simple, much like the path module and does not need a lot of documentation. All the module does is allows you to redirect urls to other urls using HTTP redirection status codes. You add redirects at admin/build/path-redirect much like you add url aliases, except they are actually redirects and not "aliases" since they perform the HTTP redirection.

http://drupal.org/node/650050 is a start based on my experience on one site.

Docs can be improved by anyone at any time. Since there's nothing concrete to fix, and D5 is now unsupported, marking as won't fix.

Added the link from the project page. D5 is now unsupported.
