+
+    <p>In addition to this, you can set a different push URL when you
+    include the <code>--push</code> flag. This allows you to fetch from
+    one repo while pushing to another and yet both use the same remote alias.

+
+    <p>Internally, the <code>git remote set-url</code> command calls
+    <code>git config remote</code>, but has the added benefit of reporting
+    back any errors. <code>git config remote</code> on the other hand, will
+    silently fail if you mistype an argument or option and not actually set
+    anything.
+    </p>
+
+    <p>For example, we'll update the <code>github</code> remote but
+    instead reference it as <code>guhflub</code> in both invocations.

+    <b>In a nutshell</b>, you can update the locations of your remotes
+    with <code>git remote set-url</code>. You can also set different push
+    and fetch URLs under the same remote alias.
