Try to improve the docs following Diataxis #302
Description
So far I have 3 vignettes:
- Getting started (diataxis: "tutorials")
- How to benchmark (diataxis: "explanation")
- R and Polars expressions (diataxis: "explanation")
and the reference page (diataxis: "reference").
The latter two are quite advanced and not of interest to the majority of users. I need more "tutorials" and how-to-guides".
