+## Publishing images
+
+Images can be built and published to a registry using the following commands. Before publishing, ensure that you have a github token with the `read:packages` and `write:packages` scopes and can authenticate to the `ghcr.io` registry.
+
+```bash
+# Make sure you are authenticated to the github registry
+docker login ghcr.io
+
+# Build the image
+docker build . --platform linux/arm64 -t ghcr.io/synthetixio/keeper:0.1.0-test
+docker build . --platform linux/arm64 -t ghcr.io/synthetixio/keeper:latest
+
+# Publish the image to a package on github
+docker build . --platform linux/arm64 -t ghcr.io/synthetixio/keeper:0.1.0-test
+docker build . --platform linux/arm64 -t ghcr.io/synthetixio/keeper:latest
