Abstract
This review provides useful background and information on how we find, vet and compile Planetary Nebulae (PNe) candidates and verify them. It presents a summary of the known Galactic PNe population and their curation in the Hong Kong/AAO/Strasbourg/H-alpha PNe catalogue, HASH. It is a simple introduction for anyone interested in working with PNe, including postgraduate students entering the field and for more general interest too.
