1. yarn install
   1. Since we are using yarn workspaces this command will install the dependencies of the root folder and go into all package’s root folders and execute yarn install. It doesn’t make much sense to invoke lerna bootstrap since it just calls yarn install itself.
2. yarn build
   1. Needed for generate the lib folder inside each package as this folder (lib) will be required to use one package in the other packages like: import { App } from 'package-1'. Yarn workspaces will symlink each package which means that /node_modules/package-1 will point to the package folder itself and since the main field of the package.json is "main": "lib/index.js", lib is required as its index.js file will be the entry point of each package.
3. yarn start

Note that you need environment variables in .env file in to root of the project
