Implementing Spine animations in Libgdx

I’ve been searching a lot for a guide on how to implement 2D animations exported from Spine to Libgdx, but all I could find was outdated tutorials and source codes. I can handle basic Libgdx but Spine seems to be completely different.
I was there, [there](https://esotericsoftware.com/spine-using-runtimes“esoterics software”) and also on lots of other sites (low rep level won’t let me post more links) but still I’ve got no idea how to do it.
Does anyone know how to add those animations properly? (doesn’t matter if it’s json or binary)
Preferably paste some code showing how to display something like spineboy so that I can see exactly what needs to be done. Any other suggestions appreciated..
