README has a bunch of wrong generic instructions

The README has some Brevo-related stuff but also looks like it has a bunch of leftover template instructions from whatever you used to generate the node SDK.

I second to this. It's mind boggling to know how much time I have spent with the documentation to just send a transactional email. Lot's of SendinBlue stuff mixed with Brevo...really confusing!

Not sure they even finished migrating everything and left it like that...ugh :(
