Hi, I'm sorry to see that you had trouble when trying to download Spine-Godot. Try refreshing the page (or holding the Shift key, and then clicking refresh), or try the link below to go to the page directly:
https://zh.esotericsoftware.com/spine-godot

If neither of those work, could you try another browser and let us know if you still have issues?

ImRains It is still available for download, but due to the fact that it automatically reflects the latest build, it loads a little slower than the body of the documentation. Could you try waiting a while after opening the documentation page?
