Thanks.  Some general documentation-related comments below.

It is generally a good idea to have a @cindex entry for the main topic
of a section/subsection.  Usually, the @cindex entry is just the node
or section name, with all of its words down-cases.  For example, here
I'd use

  @cindex connect local profiles

And similarly for the other subsection you added.

My other general comment is to never miss an opportunity of adding a
cross-reference when you reference a term or a symbol described
elsewhere in the documentation.  Never assume the reader already knows
what all the stuff you reference is about.  For example:

This will benefit from a cross-reference to where 'setq' is described
in the ELisp reference manual.

Please review the documentation changes for more cross-reference
opportunities like this one.
