While logged into the Swappa account used to register your store's location in the Repair Network, simply visit the page tied to your store. On this page, you'll see two different options: "Edit Location" and "Edit Offered Services"

You can edit your location to update simple information such as the store name, description, contact email, etc.

If you'd like to add a list of services that your store offers, you can provide this via the "Edit Offered Services" button. This will present you with a downloadable sheet that should be filled out with your shop's offerings and then uploaded back to Swappa using the "Upload price sheet" button. This will allow your store's page to display a clear list of the kinds of services you offer.
