List Your Repository
Only a plugin's own developer can list it. You prove that by publishing one small file beside your manifest, which takes about a minute.
Publish This File
Create pluginsxiv-verify.txt next to your manifest
containing only this line, then commit and push it.
Read from
Only somebody who can commit to that repository can put a file there, which is what makes this proof. Delete it once the listing is approved.
What Gets Listed
Your Own Plugins
Repositories carrying other developers' plugins are not listed, because nobody can be their author.
Every Plugin In The Manifest
Not just one. What people add to Dalamud is the whole feed, so each plugin in it needs source anyone can read. Each also gets its own entry in the index, which you can describe separately once it is listed.
A Licence File
Any licence. It is recorded and shown on your listing.
Read By A Person
Someone reads the source before it appears, and again whenever anything changes. What that does and does not mean.
Removing A Listing
Ask from the listing's own page and it is removed without argument. Deleting your account removes everything you listed with it. Either way, removal takes down the page here and nothing else: it does not reach anyone who already added your repository.
