[Suggestion] Set policy for prefered links

[spuder]

Thanks for making this repo.

I'd like to suggest making a policy that covers the following items:

1. Are affiliate links allowed/banned/encouraged/discouraged?

Personally I'd rather see people not profiting off of this database.
By clarifying the policy on affiliate links in a README, it will provide transparency to users.

2. Are country specific links encouraged/discouraged?

For example, govee/shelly have specific stores for the USA/Europe/ect....

Do you want users to assume USA?
Ideally there should be a way to provide links to all countries and 'tag' them so users can filter based on country. (See tasmota database for an example )
