Hi, I couldn't find the right documentation on the techbase. It would great if someone can point me to the right one about creating Aurorae theme / window decoration.

I am currently using one from a third party theme. While it works great, I am having issues with drawing borders to it ( decoration.svg ). I landed on an Aurorae Designer documentation ( through Google ) which seems to be outdated since Plasma does not work the same anymore. So, I need to find a page where it talks about creating Aurorae theme for Plasma 5.18. Thanks.
