Add a mesh, give it a reasonable number of polygons Add Armature, go into transparent mode. Edit the bones using the shortcut 'e' and 'g'. Make the mesh a child of the Armature. Choose "automatic weights". Now go into the animation tab and into pose mode, try to move a bone, the mesh should follow its movement.
Let's animate the bone. Decide what you want to move, go to the frame 0 in the timeline, select the bones that you want to animate (trick, if you want, enable IK in the top right corner, under "pose options"), then press 'i' to enter a keyframe. Move forward in in the timeline, move the bone and press i again.
If you want, you can scale the the frame.
In the dopesheet, rename the animation. Export to .gltf, be sure that you export also the animation data. Check that if work in three.js. If it worked, try to add a new animation. Go back to blender, go into the animation tab, choose dopesheet view and then choose Action Editor. Create a new action and give it another name.
