 Extensions uploaded to Kernel are assigned a random ID, but you can also give them a name for easier reference.
 This name must be unique within your [project](/info/projects).
 
+To retrieve an extension's metadata without downloading the archive, call `GET /extensions/{id_or_name}/metadata`.
+The response includes the extension's ID, name, size, and timestamps.

 ## Using extensions in a browser
 
 Passing the extension name or ID to the `create` method will load it into the browser.
