+## Steps To Prepare Development Environment
+
+1. Get the code ``git clone https://github.com/dw/mitogen.git``
+1. Go into the working directory ``cd mitogen``
+1. Establish the docker image ``./tests/build_docker_image.py``
+1. Build the virtual environment ``virtualenv ../venv``
+1. Enable the virtual environment we just built ``source ../venv/bin/activate``
+1. Install Mitogen in pip editable mode ``pip install -e .``
+1. Run ``test.sh``
