Need help with making custom body

[Militree]

I have never made a mod for skyrim before but strongly desire to make a custom body replacer for personal use. I have a model made in blender that has been exported as fbx already as I was told that I'd need to rig the model with skyrim's skeletons, a process which can be done in 3dsmax, but I am not too sure of what to do from here. I am not certain how to rig the model with skeletons up and so I have not done so yet. Would highly appreciate any help that can be given in regards to how I should proceed with the rest of this, even if it's something as simple as linking guides which have the answers I need. Thanks.
