There is certainly a guide for LaTeX users:
Personally, I think if you want to convince your colleagues to use Typst instead, you should give them a honest answer about the following issues:
can I do X in Typst?
LaTeX users generally have very specific usecases, especially in academia. If the migration cost is too high, people just don’t have the time to find the equivalent package in Typst, or make their own…
How much time do I need to learn Typst?
The language is very different from LaTeX. Once again, if the learning curve is too steep, that would represent a barrier to adoption. For example, people who have learnt how to write equations in LaTeX might not want to switch languages, because they have already invested time (sunk cost fallacy).
In terms of equations, it should be easy to convince them, just show them the maths section of the guide
.
Submissions
People write LaTeX because that’s often easier, and also the format that journals require for submissions. If you cannot submit a Typst manuscript, then people will not use Typst…
One argument in your favour is the improved workflow, you don’t need to install TeXLive (quite often a pain), compilation time is improved drastically, etc.
Tinymist also has a LaTeX export, so converting a Typst manuscript to a LaTeX source should be fairly straightforwardd, and would take less time than the accumulated LaTeX compilation time!
Persuasion vs coercion
You are being coerced to use LaTeX because that’s what others are using… you can just flip it around! Use Typst and force others to use it! Sometimes, you don’t need to persuade people, just strong arm them
