Instructions to populate data: 1 Using a browser with react dev tools, go to https://polaris.shopify.com/components/structure/<component type>/<name> 2 Search for a component named `PE` 3 Inspect the props, select the `properties` field and copy the value. If there are no `PE` elements (meaning there are no customizable props), simply fill in an empty array for the next step (`[]`). 4 Create a file under `data/<component type>/<name>.json`. 5 Run `node codegen.js`
