+# This workflow pushes new docker images on every new tag.
+#
+# On every new `vX.Y.Z` tag the following images are pushed:
+#
+# liftedinit/manifest-ledger:vX.Y.Z   # is pushed
+# liftedinit/manifest-ledger:X.Y.Z    # is pushed
+# liftedinit/manifest-ledger:X.Y      # is updated to X.Y.Z
+# liftedinit/manifest-ledger:X        # is updated to X.Y.Z
+# liftedinit/manifest-ledger:latest   # is updated to X.Y.Z
+#
+# All the images above have support for linux/amd64 and linux/arm64.
+#
+# Due to QEMU virtualization used to build multi-platform docker images
+# this workflow might take a while to complete.
