``javascript
var cluster = require('coreos-cluster');

cluster.createCluster({
numNodes: 10,
type: 'performance',
release: 'beta',
keyname: 'my-ssh-keyname',
credentials: {
username: 'your-user-name',
apiKey: 'some-key-here',
region: 'iad'
}
}, function(err, results) {
// will callback with a functional cluster
});
`

As coreos-cluster is built on pkgcloud, the next step is to add a provider option that allows you to use different compute providers within pkgcloud`.
