Need help adding new models and animations for units

[AuroraDelta]

I'm trying to add a new unit to the game, and I have an example-model set up and all but I'm having problems figuring out the steps for putting it in (visually). I have the code and everything set up and working using a sectopod model right now, so I just need to figure out how to create a new archetype and import the model and animations into the game, but I'm lost. Can anyone walk me through the steps on this?
