How do I add a rig to a downloaded character?

I found a model on the Internet, I want to add it to my project, but there is a problem, it does not have a rig or a skeleton. How would it be possible to add it in a Bloeder, but how exactly, can a tutorial of some kind?

Hey @Metallic_emperor

I am too also beginner to this sort of thing , im a logic programmer more than a graphic artist.

However i did find this

It is how to rig a model to the ue 5 mannequin. I enjoyed it and got mine to work quite well.

You will have ro install the blender plugin, but it is free (you do have the option to donate so do so if you can) .

You only need the unreal version download , there are others but they not necessary for it to work
