pdf-tools documentation

[Julius Hamilton]

Hey,

I am relatively new to Emacs.

I am trying to learn how to use pdf-tools, for example its highlighting
features.

I noticed on its official page, https://github.com/politza/pdf-tools, it
has a lot of instructions about installation, and a list of some commands,
but there's no link to any complete documentation which includes all
features.

How can I learn about its features in detail?

Should I use some kind of Emacs help command about the library?

Thanks very much,
Julius
