+### Developing with Docker
+
+The intention of the Docker configurations in this directory is to enable anyone to develop and test NuCypher on all major operating systems with minimal prerequisites and installation hassle.
+
+#### quickstart
+
+* install [Docker](https://docs.docker.com/install/)
+* install [Docker Compose](https://docs.docker.com/compose/install/)
+* cd to dev/docker (where this README is located)
+* `docker-compose up` **this must be done once to complete install**
+
+
+Then you can do things like:
+* run the tests:
+`docker run -it dev:nucypher pytest`
+* start up an ursula:
+`docker run -it dev:nucypher nucypher ursula run --dev --federated-only"`
+* open a shell:
+`docker run -it dev:nucypher bash`
+
+* try some of the scripts in `dev/docker/scripts/`
+
+**tested on (Ubuntu 16, MacOS 10.14, Windows 10)*
+
+From there you can develop, modify code, test as normal.
+
+### other cases
+
+* run a network of three independent Ursulas
+`docker-compose -f 3-ursulas.yml up`
+*  get the local ports these ursulas will be exposed on
+`docker ps`
+* to stop them...
+ `docker-compose -f 3-ursulas.yml stop`
