docs: update demo

[hverlin]

• Update the demo to show that one can install multiple tools:

demo.mp4

• Add transcript

• Update readme with a video (instead of gif) + additional examples

if the demo.gif is not used you can probably removed it

[hverlin]

Yeah, I can remove it 👍
The other option I was thinking about is to leave the gif in the readme and go to the demo page if one clicks on it ?

[acesyde]

the mp4 can be paused / resume, it's a huge advantage imo

[hverlin]

Yeah, I agree. So my idea would be to have the video as .mp4 on the demo page only - while we leave the .gif in the Readme.

The .gif will work everywhere, while the video is not shown in some markdown renderer. If the user tries to click on the .gif to pause it, then it will send them to the demo page where they can see the transcript + play/pause the video. I think this will also avoid having to host it through GitHub 🤔

[btpemercier]

You're right

[acesyde]

seems to not be used

@jdx, Given the discussion in #4414, maybe I should update the demo to show mise exec first as well?
