+Alternatively, RhodeCode can be set up with Apache under mod_wsgi. For
+that, you'll need to:
+
+- Install mod_wsgi. If using a Debian-based distro, you can install
+  the package libapache2-mod-wsgi::
+    aptitude install libapache2-mod-wsgi
+- Enable mod_wsgi::
+    a2enmod wsgi
+- Create a wsgi dispatch script, like the one below. Make sure you
+  check the paths correctly point to where you installed RhodeCode
+  and its Python Virtual Environment.
+- Enable the WSGIScriptAlias directive for the wsgi dispatch script,
+  as in the following example. Once again, check the paths are
+  correctly specified.
