Create a `.credentials` file with `client_id:secret` from https://develop.battle.net/access
With no crontab execute `python3 updater.py`.
Crontab, every day at 12:30h:
```
30 12 * * * time python3 updater.py
30 12 * * * cron.sh
```
Only `US` region is explored because all API are the same and this is the default API for Blizzard.
Without `locale` we get all the translations, so I don't iterate through locales. If you ask for a locale, you get the value right in the field.
