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;
}
