+### Living on the edge: using weekly snapshots
+
+OCI images snapshotted from `master` are published weekly to Github Container Registry:
+
+> https://github.com/rake-compiler/rake-compiler-dock/pkgs/container/rake-compiler-dock-snapshot
+
+The images are named `ghcr.io/rake-compiler/rake-compiler-dock-snapshot` and are tagged with the platform name (e.g., `ghcr.io/rake-compiler/rake-compiler-dock-snapshot:x86_64-linux`.
+
+These images are intended for integration testing. They may not work properly and should not be considered production ready.
+
+
 ## Environment Variables
 
 Rake-compiler-dock makes use of several environment variables.
