    ## Mongo DB Atlas Setup Instructions
       	
    To use this service, you need to supply Mongo Atlas credentials. 
    We will need:
        
    * Public key
    * Private key
    * Project ID
        
    You will need to log into Mongo Atlas or [create a new account](https://www.mongodb.com/cloud/atlas/register) to obtain these values. 
        
    To learn how to create an API Key on Mongo Atlas, please see: 
    [https://www.mongodb.com/docs/atlas/configure-api-access/#invite-an-organization-api-key-to-a-project](https://www.mongodb.com/docs/atlas/configure-api-access/#invite-an-organization-api-key-to-a-project)
