I fixed the CORS header, but still not seeing the README (which makes sense give the above, the browser isn't asking for it):

In case anyone else needs it:

```

map $request_uri $allow_origin {

default "";

~^/[a-z0-9]+/[a-z0-9]+/raw "*";

}

```

location / {

...

add_header Access-Control-Allow-Origin $allow_origin;

}
