## Updating TLDs

To update non-extended TLDs, IANA publishes, you can retrieve them from [data.iana.org](https://data.iana.org/TLD/tlds-alpha-by-domain.txt).

After retrieving the updated list, enter them into the file `tlds-alpha-by-domain.txt`. In order to update the `TLDs` map in `tlds.go`, you can run the `gen.sh` script which will generate the contents of a `string -> bool` map. After that, you'll want to replace the contents of the existing `TLDs` map, with the one that was generated and stored in `formatted_tlds.txt`
