+Webserver configuration
+-----------------------
+
+If you want to have one URL for both gitweb and your http://
+repositories, you can configure apache like this:
+
+<VirtualHost www:80>
+    ServerName git.domain.org
+    DocumentRoot /pub/git
+    RewriteEngine on
+    RewriteRule ^/(.*\.git/(?!/?(info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
+</VirtualHost>
+
+The above configuration expects your public repositories to live under
+/pub/git and will serve them as http://git.domain.org/dir-under-pub-git,
+both as cloneable GIT URL and as browseable gitweb interface.
+If you then start your git-daemon with --base-path=/pub/git --export-all
+then you can even use the git:// URL with exactly the same path.
