Select the Linode option from the list of providers. If you haven't already provided your Linode API token you'll be asked to provide credentials. Provide a name for your credentials and paste your Linode API token into the API key field and click Add credentials.
Once you have added your credentials (or if you already had them set up) select your cluster options from the fields below.
You can also expand the More settings section and set groups and tags for your environment now or you can do this later.
Once you have made your selections, click Provision environment to begin the provision. If you have other environments to configure click Next to proceed, otherwise click Close to return to the list of environments where you will see the progress of your provision.
