 We want to encapsulate building tools and dependencies in a *development* Docker image so to ease the tools installation for developers.
 
-We want developers can use whatever editing tools (emacs, vim, Eclipse, Jupyter Notebook), so the development Docker image contains only building tools, not editing tools, and developers are supposed to git clone source code into their development computers, instead of the container running the development Docker image.
