lake of installation guidelines

Hello,
Maybe sometime is missing the reedme.md. I try to build using ubuntu 18.04 and node v10.15.1

After cloning the project and cd into, I have:

~/program/DeepJS$ ng build
Could not find module "@angular-devkit/build-angular" from "/home/andradgu/program/DeepJS".
Error: Could not find module "@angular-devkit/build-angular" from "/home/andradgu/program/DeepJS".

it seem you need to run npm install --save-dev @angular-devkit/build-angular to install a missing dep.
