Hi @hrishikesh,
You are right to say that it is not in my repo. When building the app, it automatically removed it from the folder. What I did then, is to add it manually to the folder after the build operation. Seeing that it wasn’t working, I deleted it and made a new deploy without it, for no logical reason 
.
So if I understand well, I am totally messing up with my files 
However, I’m still confused about what I should concretly type in netlify.toml and in _redirects…
I would really appreciate if you could show me how to configure these files. All this is new to me
Thank you
