Tech Work Overseas: Country Guides

Would love to see one for Spain (1 year digital nomad visa, 3 years if you apply in country, eligible for perm residency at 5 years, etc). Someone else put together a list of digital nomad visas here https://lookerstudio.google.com/reporting/b58914ce-b98d-4330... if inspiration is needed.

Any idea how to register as a micropreneur online in France? Or a SASU?
