+===================
+
+For recipes that fetch release tarballs from github, the ``github-releases``
+class sets up a standard way for checking available upstream versions
+(to support ``devtool upgrade`` and the Automated Upgrade Helper (AUH)).
+
+To use it, add ``github-releases`` to the inherit line in the recipe,
+and if the default value of :term:`GITHUB_BASE_URI` is not suitable,
+then set your own value in the recipe. You should then use ``${GITHUB_BASE_URI}``
+in the value you set for :term:`SRC_URI` within the recipe.
