[SQLObject] New user: tutorial available?

I'm not a full-time developer but have a couple of desktop applications to
build. The backend is postgresql-12.7 (tables built and holding data), the
UI is TKinter (python-3.7.2) and the connector is psycopg2-2.8.6. All this
runs on Slackware64-14.2.

The SQLObject web site's documentation page has a list of links. Are the
docs available as a downloadable PDF file? Is there a tutorial so I can
learn how to start and become familiar and comfortable with the tool?

TIA,

Rich
