An Envelope is a container that holds Documents to be sent to Recipients. It organizes and manages the signing process for those documents.

Recipients interact with an envelope during a process called a Ceremony. In this process, the documents are presented to the recipient, allowing them to review and take specific actions, such as signing.

Once all recipients have completed their required actions, the envelope is completed. At that point, a Deliverable, which includes the signed documents and an audit log, is generated and sent to the recipients.
