4. Open a terminal and navigate to dors-shipping-zone-mapper/fedex.
5. Convert the PDF to TSV using node convert_pdfs_to_tsvs.mjs.
6. Convert the TSVs to the Fedex zone mapping tree using node convert_fedex_zones.mjs.
7. Check the git diff of fedex.json to ensure the file generated correctly
8. Replace existing fedex.json file in DORS (dynamic-fulfillment-router/app/src/staticdata/carrierzone) with the newly generated tree.

To generate USPS and UPS - MI zone mappings:

3. Run sh gimme.sh to download data to /usps-zones-json.
4. Convert zone jsons to tree using node convert_usps_zones.mjs.
5. Check the git diff of usps.json and usps-upsmi-overlay.json to ensure the file generated correctly.
