Error - npm run start with Pro Advanced

Expected behavior

I want to use npm/webpack for custom build (new theme - change primary & secondary colors). Expected to run 'npm run start' immediately after a successful 'npm install', but the 'npm run start' fails.

Used the instructions at: https://github.com/mdbootstrap/mdb-starter-webpack

I expected that the file structure and configurations (pkg.json, webpack.config...) would have been setup so that I could do a build without further setup, but it appears additional steps are needed.

Actual behavior

Success: npm install git+https://oauth2:xxxx@git.mdb.../standard/mdb-ui-kit-pro-advanced Error: npm run start (see snippet)

What steps need to be taken before running 'npm run start'? I am seeing some discrepancies with the instructions on the website vs. what gets installed to 'mdb-ui-kit' folder. For example, the documented file structure does not match the structure in 'mdb-ui-kit' folder and custom scss files are named differently (_styles.scss vs. styles.scss).
