Meta description and keywords doesn't rendering in frontend

The ONLy way I can get meta data to display is using this tag:
{{ page.attached }}

There is ZERO information about this online. There is ZERO information about what tag to use in the theme to add the code, only head_title for the tag.

If Drupal is supposed to magically add the meta information like descriptions, then it was not for me. In my template there is no tag to output it. So does that mean Drupal does some sort of find and replace to inject it? Which really is not good anyway.

Using {{ page.attached }} for me outputs all the correct extra META tags now. The strange thing is, even though I added that tag AFTER my tag, the code is added above it which is very strange and annoying.

Thanks for spotting that. I opened 📌 Document that {{ page.attached }} must be in html.html.twig Active to add it to the documentation.
