            accessKey: "<s3 access key>",
            region: "<s3 region>",
            bucketName: "<s3 bucket name>"
            }      
        }


## As a Library

### Import 

    const restore = require('s3-mongo-restore');

### Create a configuration Object

    var restoreConfig = {
      mongodb: "mongodb://localhost:27017", // MongoDB URI
        s3: {
          secretKey: "<s3 secret key>",     // S3 Secret Key
          accessKey: "<s3 access key>",     // S3 Access Key
          region: "<s3 region>",            // S3 Region
          bucketName: "<s3 bucket name>"    // S3 Bucket Name
        }      
    }
#### Call the Function and pass configuration object to it

This module exposes two functions, `List` and `Restore`. `List` is used to list all the backups in the database and takes just the configuration object. `Restore` is used to restore a database and takes the configuration object and the name of database. 

    //List
    restore.List(restoreConfig)
      .then(result => {
        // When everything is ok, result is an Object containing information about all the backups
          console.log(result);
    }, error => {
        // When Anything goes wrong!
        console.log(error);
    });

    //Restore
    restore.Restore(restoreConfig, "<A backup name>")
        .then(result => {
            console.log(result);
        }, error => {
            console.log(error);
        });
