Contribution Guidelines

Install

• Required Node
• We recommend using nvm
• Clone the project on to your computer
• Run nvm install to ensure you have the correct Node version
• Run npm install to install project dependencies
• Ensure your editor is set up to use editorconfig, Prettier, Eslint and Stylelint

Development

• Run nvm use to set Node to the correct version
• Run tests via npm run test
• Run linting via npm run lint
• Run updates to Readme (if rules have changed) via npm run write-rules
• Run preflight checks before committing final code via npm run preflight
• Note: When working with the rule set, only modify the index.js file, not the .eslintrc file as it is for local linting only
