No worries, here is the process:

1. Register a cool domain name for your show (or upload your videos onto an existing hive-tube host)
2. Find a good webhosting provider (ubuntu/nginx) and install the free peertube server package, then click the "Install" button to easily install Hive-Tube (see the screenshot from the admin console below).
3. Upload your videos to your channel there and share the links.

I can help you get your server instance federated too which will get a lot more traffic to your videos, just let me know if you want some help. I use matrix/element at agorise.chat
