 Robert created this list to keep track of things that should be in our manual. Especially the small problems we have run into in MUDE and other projects.
 
-- use the right HTML tags for images (described {ref}`here <image-tag-example>`)
-- watch out for `png` versus `PNG`
-- trick for creating download link for PDFs (see Archive weekly summary pages); requires an `eval-rst` admonition, which can't be placed inside some objects (maybe someone can test this, and see if an inline option is available)
-- 2 interesting comments from Quinten about MyST extensions in [this GL Issue](https://gitlab.tudelft.nl/mude/archive-2022/-/issues/25#note_163123)

-### Example of image tag
-
-This was found in the MUDE Archive, [Issue 29](https://gitlab.tudelft.nl/mude/archive-2022/-/issues/29).
-
-It looks like the `figure` tag
-```
-<figure>
-  <IMG SRC='...'>
-</figure>
-```
-is not supported. but the `img` tag is:
-```
-<img src="...">
-```
-see examples [here](https://jupyterbook.org/en/stable/content/figures.html) (no `figure` tag mentioned for HTML, only Markdown)
