Okta Sign In widget - Salesforce Community Integration

We are thinking to embed the Okta Login widget on the salesforce communities login page so that salesforce community users would not need to leave the salesforce login page. Is there any documentation available on how to achieve this and if Okta would support this on salesforce communities pages?
