 There are many more uses cases to be explored; but, I will leave that to you. If you brave enough...
 
+## Releasing
+
+We use goreleaser to release cross-compiled versions.  The steps to release are:
+
+```
+export GITHUB_TOKEN="A_GITHUB_TOKEN_THAT_HAS_CORRECT_ACCESS_ENTITLEMENTS"
+VERSION="0.0.30"
+rm -rf dist
+git tag -a $VERSION -m "Some description of the release"
+docker run --rm --privileged \
+-v $(pwd):/go/src/github.com/immutability-io/vault-ethereum \
+-v /var/run/docker.sock:/var/run/docker.sock \
+-w /go/src/github.com/immutability-io/vault-ethereum \
+mailchain/goreleaser-xcgo goreleaser --rm-dist
+sha256sum dist/*.zip > dist/SHA256SUMS
+gpg --detach-sign dist/SHA256SUMS
+```
+
+If you wish to run goreleaser locally, the following will give you a snapshot build for darwin, linux, and windows.
+
+```bash
+docker run --rm --privileged \
+-v $(pwd):/go/src/github.com/immutability-io/vault-ethereum \
+-v /var/run/docker.sock:/var/run/docker.sock \
+-w /go/src/github.com/immutability-io/vault-ethereum \
+mailchain/goreleaser-xcgo goreleaser --snapshot --rm-dist
+```

 None of this would have been possible without the fantastic [tutorial](https://www.hashicorp.com/blog/building-a-vault-secure-plugin) on Vault Plugins by Seth Vargo. Seth is one of those rare individuals who can communicate the simple essence of a complex technology in practical terms.
