Without looking I cant tell if you need to remove hinge spring, if so, you need a hinge spring compressor or equivalent. There could be safety issues with removing that spring. It could come flying out of there. Safety is your responsibility. If spring removal is required, using a towel over the spring may offer some protection.
If any electricals going into the door, you will have to deal with the wiring.
To remove the door hinge pin clips, spread the clips and move them above the recess on the pin; When the pin is removed, the clip will ride on the pin and fall free of it.
You may need to use a pair of locking pliers on the pin to remove. I could tell more if I could look at it. And you will probably need to support the door. Some of this you will have to use your own judgement.
