+# Getting Started
+
+You will need to clone the this repo and checkout the docker branch. Then modify the resources in the openshift directory with your project namespace, and modify the route with your clusters domain. When building the docker image tag it with your container registry that is used by openshift.
+
+```
+git clone https://github.com/mjj203/fresco-docker.git
+cd fresco-docker
+git checkout docker
+docker login $registry
+docker build -t $registry/fresco:latest -f Dockerfile .
+docker push $registry/fresco:latest
+oc login
+oc apply -f openshift/deployment-fresco.yaml
+oc apply -f openshift/service-fresco.yaml
+oc apply -f openshift/route-fresco.yaml
+```
