| Enumerations | Contains information on how to work with enumerations. |
| Components | Contains information on how to work with components. A component is a predefined set of fields that can be reused across models and content entries. |
| Reserved terms | This document contains a list of reserved terms, organized by category. Attempting to use these terms will result in a warning, informing you that you must use a different word instead. |
| Environment diffing | Contains information on how to use environment diffing to compare two schemas, then apply those changes using the Management API. |
