IV. Uploading
When you go to upload your .zip archive to the Nova add-ons pages, just ignore the compression/encoding instructions it tells you — these are global to all the Ambrosia add-on files and were not meant for Nova. Be advised that an archive of more than about a dozen megabytes may fail to upload. If this happens to you then you will need to separate your distribution folder into smaller parts, archive these separately, and upload them separately. Do not use segmented files as this will complicate extraction.
Lastly, make sure you follow the Add-ons Directory Rules before uploading or your plug-in may be deleted (you can see plug-ins that have been deleted here). In particular, you must include your email address in the description in case the moderators need to contact you. Depending on activity, the turnaround can take a few days but pretty soon your plug-in should be available in the Nova add-on files.
