-### Set Up SSL
-
-OAuth authentication requires SSL. The server expects SSL key information in the `/nginx/ssl.crt` and `/nginx/ssl.key` files in the project directory. 
-
-To create a self-signed SSL key:
-
-1. `cd recordviewer/nginx`
-1. `openssl genrsa -des3 -passout pass:x -out server.pass.key 2048`
-1. `openssl rsa -passin pass:x -in server.pass.key -out ssl.key`
-1. `openssl req -new -key ssl.key -out server.csr`
-
-    When prompted for a 'challenge password', press return, leaving the password empty.
-
-1. `openssl x509 -req -days 365 -in server.csr -signkey ssl.key -out ssl.crt`
-
-For more information, see these [Creating a Self-Signed SSL Certificate](https://devcenter.heroku.com/articles/ssl-certificate-self).
