You just use three backticks to start and end a code block, it’s just markdown.
e.g.
version: '3.4'
services:
vaultwarden:
image: vaultwarden/server:latest
restart: always
# environment:
# SIGNUPS_ALLOWED: 'false'
# ADMIN_TOKEN: 'your authentication token'
ports:
- '127.0.0.1:8200:80'
volumes:
- vaultwarden-data:/data/
...
Yeah, it’s only communities that people on your instance search for/subscribe to afaik. So if you’re the only one on your instance then you have control over that.
Further to that it’s only the post objects (and comments, etc.) that is replicated all pics and videos are just URLs. even when you upload a picture with the post, that’s just uploaded to the instance and the link to it is the link of the post, even on other instances the images are fetched from the original source from the client side. I do believe each instance does local thumbnaling.
The main difference that has me using LibreTube rather than NewPipe is because my subscriptions are on my piped account so they are synced between phone and desktop (browser). Piped is built on top of NewPipe’s extractor library anyway.
