 ## Updating Region Data
 
 The `regions.json` file can be updated manually by running `yarn importRegions` which triggers the `update.ts` script in `devTools/regionsImporter` and prints out a diff if anything has changed. If, after looking over the changes, everything looks good-to-go you can commit the updated `regions.json` and merge back into `master`.
 
 > Note: pay particular attention to changes in `slug` values for countries since this determines the URL of their country page. If a slug changes, be sure to add a redirect from the old value to the new one in WordPress.
