Sakimi Chan (one of the bigger artists on Patreon) posted a tutorial this month for how she rigs up her animation in Spine:

When I first saw her animating her drawings, I figured she must be using Spine, so it's good to see how she does it!
Hope things are going well with the spine team, and hope other artists are also going to start bringing their art to life with Spine 😃 (I really need to go through the tutorials- I haven't gotten much time to work with it since way before all the cool mesh animation tutorials)
