Shallot Growing 2021

I've never grown onions or shallots from seed, but have some zebrune seeds on order. No idea what to do with them though. I'll jump that fence when they arrive.
I've put some of last year's small red sun shallots in modules of spent compost to wait til the ground is ready. Looked at doing the same for golden gourmet but wasn't too sure about splitting them up. Once split the 'cloves' were fresh and crispy like onions rather than papery and thought they might rot. Not thought of a solution to that one yet.
