Commit Message

docs: document default environment separator (#724)

The first time I stumbled upon this I wasted like 2 hours trying to
figure out how to use environment variables. It really was not obvious
that a dot would be the default separator. And it is not even easy to
figure out when using bash, because it refuses to accept dots!

Today I was starting a new project and it is really bothering me that
this is not documented, so here is a pr with just some docs. I did not
bother creating an issue, because it felt excessive.

Hopefully I did not do anything wrong and this will pr be accepted.
