+**Support lifecycle**
+
+The supported lifecycle of each build image is directly correlated with the
+upstream support cycle. Each supported upstream release is generally offered on
+sr.ht, as well as the bleeding edge or development releases if applicable. No
+sooner than two weeks after a release becomes unsupported upstream, it will be
+unsupported on builds.sr.ht - and anyone who's submitted recent builds using
+those images will get an email warning them of the impending breakage.
+
+It's recommended that you use aliases like "alpine/latest" or "debian/testing"
+rather than using a specific release in your build manifests.
