+
+## Playbooks
+
+### Update Docker image tag
+
+1. Pull down images and create a manifest:
+    ```sh
+    $ export VERSION=0.12.4
+    $ export MINOR_RELEASE=0.12
+
+    $ docker pull --platform linux/amd64 gogs/gogs:${VERSION}
+    $ docker tag gogs/gogs:${VERSION} gogs/gogs:${MINOR_RELEASE}-amd64
+    $ docker push gogs/gogs:${MINOR_RELEASE}-amd64
+    $ docker pull --platform linux/arm64 gogs/gogs:${VERSION}
+    $ docker tag gogs/gogs:${VERSION} gogs/gogs:${MINOR_RELEASE}-arm64
+    $ docker push gogs/gogs:${MINOR_RELEASE}-arm64
+    $ docker pull --platform linux/arm/v7 gogs/gogs:${VERSION}
+    $ docker tag gogs/gogs:${VERSION} gogs/gogs:${MINOR_RELEASE}-armv7
+    $ docker push gogs/gogs:${MINOR_RELEASE}-armv7
+
+    $ docker manifest create \
+    	gogs/gogs:${MINOR_RELEASE} \
+    	--amend gogs/gogs:${MINOR_RELEASE}-amd64 \
+    	--amend gogs/gogs:${MINOR_RELEASE}-arm64 \
+    	--amend gogs/gogs:${MINOR_RELEASE}-armv7
+    $ docker manifest push gogs/gogs:${MINOR_RELEASE}
+
+    # Only push "linux/amd64" for now
+    $ echo ${GITHUB_CR_PAT} | docker login ghcr.io -u <USERNAME> --password-stdin
+    $ docker pull --platform linux/amd64 gogs/gogs:${VERSION}
+    $ docker tag gogs/gogs:${VERSION} ghcr.io/gogs/gogs:${MINOR_RELEASE}
+    $ docker push ghcr.io/gogs/gogs:${MINOR_RELEASE}
+    ```
+2. Delete ephemeral tags from the [Docker Hub](https://hub.docker.com/repository/docker/gogs/gogs/tags).
+
+### Compile and pack binaries
+
+All commands are starting at the repository root.
+
+- macOS:
+	```sh
+	# Produce the ZIP archive
+	$ TAGS=cert task release
+	```
+- Linux:
+	```sh
+	# Produce the ZIP archive
+	$ TAGS="cert pam" task release
+
+	# Produce the Tarball
+    $ export VERSION=0.12.4
+	$ cd release && tar czf gogs_${VERSION}_linux_$(go env GOARCH).tar.gz gogs
+	```
+- ARMv7:
+	```sh
+	# Extract the binary from the Docker image
+	$ docker pull --platform linux/arm/v7 gogs/gogs:${VERSION}
+	$ docker run \
+		--platform linux/arm/v7 \
+		-v ${PWD}:/opt/mount/ \
+		gogs/gogs:${VERSION} \
+		bash -c "cp /app/gogs/gogs /opt/mount/"
+	```
+- ARMv8:
+	```sh
+	# Produce the ZIP archive
+	$ TAGS="cert pam" task release
+
+	# Produce the Tarball
+    $ export VERSION=0.12.4
+	$ cd release && tar czf gogs_${VERSION}_linux_armv8.tar.gz gogs
+	```
+- Windows:
+	```sh
+	$ TAGS=cert task release
