+
+      <para>The <literal>Quarterly</literal> branch provides users
+	with a more predictable and stable experience for port and
+	package installation and upgrades.  This is done essentially
+	by only allowing non-feature updates.  Quarterly branches aim
+	to receive security fixes (that may be version updates, or
+	backports of commits), bug fixes and ports compliance or
+	framework changes.  The Quarterly branch is cut from HEAD at
+	the beginning of every (yearly) quarter in January, April,
+	July, and October.  Branches are named according to the year
+	(YYYY) and quarter (Q1-4) they are created in.  For example,
+	the quarterly branch created in January 2016, is named 2016Q1.
+	And the <literal>Latest</literal> branch provides the latest
+	versions of the packages to the users.</para>
+
+      <para>To switch from quarterly to latest run the following
+	commands:</para>
+
+      <screen>&prompt.root; <userinput>cp /etc/pkg/FreeBSD.conf /usr/local/etc/pkg/repos/FreeBSD.conf</userinput></screen>
+
+      <para>Edit the file
+	<filename>/usr/local/etc/pkg/repos/FreeBSD.conf</filename>
+	and change the string <emphasis>quarterly</emphasis> to
+	<emphasis>latest</emphasis> in the <literal>url:</literal>
+	line.</para>
+
+      <para>The result should be similar to the following:</para>

+      <programlisting>FreeBSD: {

+  signature_type: "fingerprints",
