+# Kubernetes Build Pack
+Kubernetes Build pack serves to build and deploy [Shopsys Framework](https://github.com/shopsys/shopsys) application using Docker, Kubernetes, Terraform etc. that are preinstalled into Dockerfile which can be used later as an image.
+
+## Requirements
+Docker
+
+## What it contains
+[Docker](https://www.docker.com/)
+
+[Kubernetes - kubectl](https://kubernetes.io/)
+
+[Terraform](https://www.terraform.io/)
+
+[Yq](https://github.com/kislyuk/yq)
+
+[Google Cloud SDK](https://cloud.google.com/sdk/)
+
+[Kustomize](https://github.com/kubernetes-sigs/kustomize)
+
+## How to use
+Basic concept of usage of this image is to mount your repository into container volume from which you can perform all your tasks related to deploying Shopsys Framework.
+
+*Code example*: 
+
+```
+cd /my-project/
+
+docker run \
+    -v $PWD:/tmp \
+    -v /var/run/docker.sock:/var/run/docker.sock \
+    -v ~/.kube/config:/root/.kube/config \
+    shopsys/kubernetes-buildpack
+    --rm 
+    <your scripts>
+```
+
+## How to extend
+What if I want to work with some technology that is not included in shopsys/kubernetes-buildpack?
+
+You can extend our image in `Dockerfile` and install applications and tools that you require.
+
+```Dockerfile
+FROM shopsys/kubernetes-buildpack
+
+# install tools you want here, eg. Python
+RUN apk add --update --no-cache python3
+```
