 ## Additional Spine project guidelines:
 - Do not use minify on export of C3 project.
-- Do not use worker mode for C3.
+- Worker mode supported for C3.
 - For jumping or large movments, animate Spine character 'in place', don't do large translations in the Spine project.
 - Use C3 events and movement to do the large translations in the C3 project instead (e.g. a long jump.)
 - If animation is clipping against the bounds of the C3 object, you can use the property bbox override and values to control the bounding box size and center offset. The values are based on Spine project coordinates.
