The existing Lucene.Net home page at http://lucene.apache.org/lucene.net/ is still based on the incubation, out of date design. This JIRA task is to bring it up to date with other ASF project's web page.
The existing website is here: https://svn.apache.org/repos/asf/lucene/lucene.net/site/
See http://www.apache.org/dev/project-site.html to get started.
It would be best to start by cloning an existing ASF project's website and adopting it for Lucene.Net. Some examples, https://svn.apache.org/repos/asf/lucene/pylucene/site/ and https://svn.apache.org/repos/asf/lucene/java/site/
