Issue in the ReadMe section "Deploying". Build instruction does not match any command defined in package.json

Step 2 of the deployment instructions states the following:

Install npm and run npm install via command line then run npm run build.

The only commands define for run in package.json are the following:

  "scripts": {
    "start": "npm-run-all --parallel watch:sass watch:ts",
    "copy:node_modules": "./node_modules/.bin/cpx './node_modules/@esri/**/*.js' app",
    "watch:ts": "tsc --watch",
    "build:ts": "tsc",
    "build:sass": "./node_modules/.bin/node-sass styles/main.scss styles/main.css",
    "watch:sass": "./node_modules/.bin/node-sass --watch styles/main.scss styles/main.css",
    "deploy": "npm run build:sass & npm run build:ts & npm run copy:node_modules"
  },

Is that safe to assume that the command to run should be npm run deploy, which run all the build commands?
