 ## Development guide
 
+### Building the docker image for local execution
+
+**Simulate the docker build that takes place on openshift with:**
+
+```
+s2i build file://$(pwd) --copy --context-dir=app-config/nginx/ centos/nginx-112-centos7 cara-nginx-app
+s2i build file://$(pwd) --copy --context-dir=./ centos/python-36-centos7 cara-voila-app
+cd app-config
+docker-compose up
+```
+
+Then visit localhost:8080.
