Create a page to list public instances
In similar spirit as Invidious (alternative YouTube frontend), it would be nice to have a list of public instances that users could use aside from the default instance.
The page could also promote send-docker-compose to encourage users to self-host; or even better, make it public and add itself to the list. This subsequently can reduce the load on the default instance.
https://fileupload.ggc-project.de/ is an example public Send instance.
GitLab doesn't support public-editable wiki page, a user needs to be granted developer permission to edit a wiki page. I think the most suitable way is to create a docs/public-instances.md
file in this repo.
