+**Multi-architecture builds**
+
+The newest images (Debian-based, *0.19+*) provide built-in support for multiple architectures. Running `docker pull` on any of the supported platforms will automatically choose the right image for you as all of the manifests and artifacts are pushed to the Docker registry.
+
 **Picking the right tag**

 - `ruimarinho/bitcoin-core:latest`: points to the latest stable release available of Bitcoin Core. Use this only if you know what you're doing as upgrading Bitcoin Core blindly is a risky procedure.
