How we setup a sub-directory on nGinx?


thats embarrassing but im failing it for a half an hour, so i will ask (cc @gnumdk)

i have Ghost on:
and works on

i have Gatsby on:
and i want it to work on

Gatsby is a static generator so it only needs to serve index.html ,and SSL if that matters. if someone can share a working .conf would be nice!
