+## Introduce changes in dvote-protobuf
+
+```sh
+git clone git@github.com:vocdoni/dvote-protobuf.git && cd dvote-protobuf
+git checkout -b feat-add-DummyMessage # don't use slashes (/)
+cat >> src/vochain/vochain.proto << EOF
+message DummyMessage {
+        bytes payload = 1;
+}
+EOF
+git commit . -m "add DummyMessage"
+git push --set-upstream origin feat-add-DummyMessage
+```
+
+if you use slashes in the branch name (say, `example/branch-name`), you won't be able to `go get go.vocdoni.io/proto@example/branch-name` in the next step due to a [go issue]:https://github.com/golang/go/issues/32955
+
+## Stage them in a PR of dvote-protobuf
+
+Now create a PR:
+
+https://github.com/vocdoni/dvote-protobuf/pull/new/feat-add-DummyMessage
+
+and wait a minute for the CI to run and auto commit the build changes
+("auto build commit" is pushed to the PR automatically)
+
+## Use that "staged" dvote-protobuf in vocdoni-node
+
+```sh
+git clone git@github.com:vocdoni/vocdoni-node.git && cd vocdoni-node
+git checkout -b wonderful-feature # here it doesn't matter if you use slashes (/)
+go get go.vocdoni.io/proto@feat-add-DummyMessage # this will pull the code from your PR
+go mod tidy
+git add go.mod go.sum
+git commit -m "bump go.vocdoni.io/proto@feat-add-DummyMessage"
+git push --set-upstream origin wonderful-feature
+```
+
+Now if you create a PR in vocdoni-node with your `wonderful-feature` branch, you'll see the CI of vocdoni-node pulls the dvote-protobuf from feat-add-DummyMessage
