I've put together two guides: mantis curation (by Lohit Garikipati), and one about labels (locality, field number, and determination labels). They will no doubt be improved over time, but feel free to take a look at those and critique them. I'm planning to do the guides about pinning blocks and making a personal database, and everything that entails, in the coming weeks as time permits.
Thank you, Lohit, for sharing your advice for curating mantises.
