I'm opening a new topic because it is related to the skins update packaging rather than the code itself. Feel free to move if needed.
The latest (2021.03.20) ZIP file contains two unexpected files in the top folder.
I'm not sure the "{EN} Export for Neo4j.zip" file should be included, but I'm pretty sure the "nieuwe-skin-nl-be.pdf" does not belong there.
The "nieuwe-skin-nl-be.pdf" contains the guidelines for the installation of a skin update in Dutch, but I understand the confusion. I will provide an extra "{NL-BE} Richtlijnen" (richtlijnen = guidelines) folder in the next version of the NL-BE Kit.
