Please help with some Html formatting on Github repo

seeking assistance to add some styling from the official developers pages on my repo at in my repo at custom-ui/INSTALLING.md at 78df205622bacd72cc8f38d457886e5aa0f811a4 · Mariusthvdb/custom-ui · GitHub

as you can see on those dev pages, this is used:

---
title: "Registering Resources"
---

and a bit down :

:::note

This tab is only available when the active user's profile has "advanced mode" enabled.

:::

I tried copying that, but it isnt accepted, and Ludeeus explained to me this is Docusaurus features.

not familiar with that, I hope someone can help me create those tags, or use alternatives for it.

for now, Ive changed to

# Installing Custom-ui

which is fine except for the automatic underline per chapter level. Even here looks like

Installing Custom-ui :slight_smile:

I wouldn’t know of an alternative for the nice little background on the “this tab is only available etc etc”

lastly, I need a way to set a size on some pictures in my repo, but haven’t found a way to do so either.

All in all, please have a look, thanks!
