Identification of Channel Export icon missing (as are instructions for use)

[jcogs-design]

Description of the problem
Despite a link to the page in the opening text of the Channel Sets documentation page - vis -

When you export your Channel Set, you’re provided with a zip file that contains all of the data needed to recreate that same Channel on any other ExpressionEngine installation by using the Channel Set Import page.

The page linked to contains no information on how to export a channel set.

Additional context
In the end I found the instructions needed in stackexchange... what is needed is for this text to be added to the main documentation (and perhaps a heading added).
