+      <p>Buildroot's Long Term Support (LTS) branch is maintained thanks to the
+	<a href="https://mind.be/buildroot-lts">LTS Sponsoring program</a>. Its
+	goal is	to provide three or more years of stable support for your
+	Buildroot deployments. The success of this venture depends on the
+	generosity of sponsors like you, willing to make a change and ensuring
+	the longevity of Buildroot's reliability.</p>
+      <p>Prior to this initiative, LTS maintenance was handled by volunteers.
+        As a result, it was limited to just one year. In addition, it diverted
+        maintainer time away from mainline development, slowing  down the overall
+        progress of the project.</p>
+      <p>Thanks to LTS sponsoring, the entire community gets access to a better
+        and longer maintained LTS branch. The sponsors get access to some
+        additional perks, such as selecting which packages to focus on, reports
+        with information that is relevant for you, and direct contact with the
+        LTS maintainers.</p>
