README: Update and remove references to distros, replace w/ DISTRO_FEATURES

Remove distros, instead of specifying an oe or poky example distribution,
we are moving to enabling the components using DISTRO_FEATURES.  This will
make it easier for a user to enable selinux on a custom distribution, or on
a project specific basis.

 Building the meta-selinux layer
 -------------------------------
 In order to add selinux support to the poky build this layer should be added
-to the bblayers.conf file.  In addition you should modify your local.conf
-to specify the "poky-selinux" distribution.

-An "oe-selinux" distribution is also included as a convienence for people
-working with this layer, without the additional Poky meta data.  This
-approach may work, but is not generally tested by the maintainers.
+to your projects bblayers.conf file.
 
-e.g. DISTRO="poky-selinux"
+By default the selinux components are disabled.  This conforms to the
+Yocto Project compatible guideline that indicate that simply including a
+layer should not change the system behavior.
 
+In order to use the components in this layer you must add the 'selinux' to the
+DISTRO_FEATURES.  In addition to selinux, you should be sure that acl, xattr and
+pam are also present.
+e.g. DISTRO_FEATURES_append = " acl xattr pam selinux"
 
-Using different versions of linux-yocto
----------------------------------------
-To prepare selinux enabled images using different ver. of linux-yocto,
-we can choose supported versions of linux-yocto,
-currently supported: v3.14, v3.19, v4.1(by default).

-* enable the preferred linux-yocto to local.conf or oe-selinux.conf
-e.g. PREFERRED_VERSION_linux-yocto_qemuarm = "3.19%"
+You must also specify a preferred provider for the virtual/refpolicy.  The
+included policies with this layer are simply reference policies and will need
+to be tailored for your environment.
