Don’t forget that « better » is the enemy of « good ».
As using LAMMPS since almost ten years, I always learned a lot from the current documentation. Especially when reading carefully. And from the previous list. This only require to carefully ask a relevant question to google or ...
So I find the lammps doc very useful

I definitely agree the LAMMPS doc pages could be improved. There is a lot of redundant info and info buried down deep in there. But I would also say that the LAMMPS documentation is far better than most research codes :)

i am not disagreeing with the fact, that the documentation can be improved; that it is vast and extremely and needlessly repetitive and unfocused. in fact, you should recall, that i have repeatedly made proposals for how i think this should be changed and the overall structure improved. and that is exactly the point of *my* criticism
here: saying that something is not good is meaningless without pointing out why and where.

that is the second point i am making (and have been making over and over again for years). documentation is something where non-developers can support the community and, both, help themselves and others by contributing improvements. at the current pace of development and availability of time of the core developers, i don't see much of a chance for any of that to happen soon (or later). that is why i am calling out people to not just say that something needs to be improved, but am asking them to make an active effort. we have a large enough user base. if only half of them makes a small contribution, that will take us already very far. ...and one does not really need to be an expert for this:
when i was in grad school, my department head would always say "you want to enter a new field of research, start by writing a review". for a long time, it didn't make much sense to me to have a beginner (and not an expert) do a review. but i have since understood why, and for software i found that this statement can be modified to "if you want to understand a software, write a tutorial" or "... rewrite the documentation". so the common excuse "i cannot write documentation because i am not an expert", does not hold: a) because experts do not understand the perspective of a beginner well, so it is difficult to write a documentation for a beginner (or intermediate or non-developer), b) writing (good!) documentation forces you to understand how something works (same as for the review writing case), so it is an opportunity to teach yourself valuable knowledge and skills, even if you never aim to become a programmer.
over many year i myself have contributed tutorials to multiple software packages, some of which are still available, and often near the beginning of my involvement with a project, and then later some of these tutorials actually ended up to become contributions to the respective codes or their documentation.
