+# GitHub Actions
+
+Create a private repository named `demo-app` on GitHub and navigate to Settings/Secrets and add the following secrets:
+
+* `DOCKER_IMAGE` eg stefanprodan/demo-app
+* `DOCKER_USERNAME` eg stefanprodan
+* `DOCKER_PASSWORD` eg my-docker-hub-pass
+
+Install podinfo CLI:
+
+```bash
+go get -u github.com/stefanprodan/k8s-podinfo/cmd/podcli
+```
+
+If you don't have golang installed go to the 
+[release page](https://github.com/stefanprodan/k8s-podinfo/releases), download the latest podcli release and add it to your path.
+
+Clone your private repository (preferable in your `$GOPATH`) and initialize podinfo.
+
+```bash
+git clone https://github.com/stefanprodan/demo-app
+cd demo-app
+
+podcli code init demo-app --git-user=stefanprodan --version=v1.3.0
+```
+
+The above command does the following:
+* downloads podinfo source code v1.3.0 from GitHub 
+* replaces golang import with your git username and project name
+* commits and pushes the code to GitHub
+
+When the code init command finishes, GitHub will test, build and push a Docker image 
+`${DOCKER_IMAGE}:${GIT-BRANCH}-${GIT-SHORT-SHA}` to your Docker Hub account.
+
+If you create a GitHub release a Docker image with the format `${DOCKER_IMAGE}:${GIT-TAG}` will be published to Docker Hub.
