 ### Development Workflow
 
 After cloning and installing all the dependencies, there are several commands available for local development:
 
--   `yarn lint` - Lints everything in src directory
--   `yarn jest` - Runs Jest over all tests in src directory
--   `yarn test` - Runs `yarn lint` and `yarn jest` together
+-   `npm run lint` - Lints everything in src directory
