I just finished setting up the hardware infrastructure to start hosting but I cannot find any specific information in the official documentation on how to set up a public Invidious instance. I understand the guide as far as just hosting an instance and watching YouTube through that goes, but how do I, for instance, give it a publicly searchable domain name that - in the best of worlds - is listed on Invidious' website?

I assume there is a better way than to start posting my instance's IP address throughout any forums that I might be active on?
