 If you want to use SELinux, chances are you will want
 to use the distro-provided policies, or install the
 latest reference policy release from

 However, if you want to install a dummy policy for
-testing, you can do using 'mdp' provided under
+testing, you can do using ``mdp`` provided under
 scripts/selinux.  Note that this requires the selinux
 userspace to be installed - in particular you will
 need checkpolicy to compile a kernel, and setfiles and
 fixfiles to label the filesystem.
 
 	1. Compile the kernel with selinux enabled.
-	2. Type 'make' to compile mdp.

 	3. Make sure that you are not running with

 Step 4 will create a new dummy policy valid for your
 kernel, with a single selinux user, role, and type.

-dummy in /etc/selinux/config, install the compiled policy
