Cloud provider keys can be managed by going to the providers link at the top right menu.
NOTE that the only supported provider right now is DigitalOcean. The rest of the instructions assume that you already have a DigitalOcean account created and you’re logged into it.
To add a new DigitalOcean provider key, click on the create provider link and add a name and your DigitalOcean API key.
You can get a DigitalOcean API key for your account from here. Make sure that the “write” scope for the API key is checked.
