First, install nginx for mac with "brew install nginx".

Then follow homebrew's instructions to know where the config file is.

1. To use https you will need a self-signed certificate: https://devcenter.heroku.com/articles/ssl-certificate-self
2. Copy it somewhere (use full path in the example below for server.* files)
3. sudo nginx -s reload
4. Access https://localhost/

Edit /usr/local/etc/nginx/nginx.conf:
