+# Docker Build & Push Action
+<p align="center">
+  <a href="https://github.com/mr-smithers-excellent/docker-build-push-action"><img alt="GitHub Actions status" src="https://github.com/mr-smithers-excellent/docker-build-push-action/workflows/test-local/badge.svg"></a>
+</p>
+
+Builds a Docker image using a `Dockerfile` in the root project directory and pushes the resulting Docker image to the private registry of your choosing.
+
+## Requirements
+
+* [GitHub Actions Beta](https://github.com/features/actions) program participation
+* Run [checkout action](https://github.com/actions/checkout) before using this action
+```yaml
+steps:
+  - uses: actions/checkout@v1
+```
+
+## Inputs
+
+| Name | Description |
+|------|-------------|
+
+## Examples
+
+### Docker Hub
+
+```yaml
+uses: mr-smithers-excellent/docker-build-push-action@master
+with:
+  image: docker-hub-repo/image-name
+  registry: docker.io
+  username: your-username
+  password: ${{ secrets.password }}
+```
+
+### Google Container Registry (GCR)
+
+```yaml
+uses: mr-smithers-excellent/docker-build-push-action@master
+with:
+  image: gcp-project/image-name
+  registry: https://gcr.io
+  username: _json_key
+  password: ${{ secrets.password }}
+```
+
+## Tagging the image using GitOps
+
+By default, this action will use an algorithm based on the state of your git repo to determine the Docker image tag. This is designed to enable develops to more easily use [GitOps](https://dzone.com/articles/what-is-gitops-really) in their CI/CD pipelines.
