+
+There are two available images for you to choose from. The default one (0.*n*) is based on
+Ubuntu 18.04, with Icinga2 from Icingas official repository. The other image (0.*n*-alpine) is
+based on Alpine 3.11, with Icinga2 from Alpines repository. From 0.1.1-alpine and up, the Alpine
+image is built on the latest Alpine. The Alpine image is much smaller in size.
