How to read about f ex "stepper.h" and other library files

Hi!
I'm a newbie drowning in new info. Watching all questions in Forum gives me valuable info.
My project is to to make my mini mill digitally controlled. Blinking "SOS" on the Arduino board works. Now I head for stepper motor controll routines.

How/were can I find out about existing .h-files and similiar library stuff?

Thankful for tips,
Railoader

Even when working in the Arduino-IDE sfer?

Here are a couple of links to basic stepper information.

The most used stepper library for multiple steppers is probably the AccelStepper library with many examples.

To start out with a single stepper there is the basic Stepper library that is included in the IDE (with a couple of examples).

Thanks a lot for the links!
I became Master of Science in electronical design and computer science 1982, was involved in designing advanced stepper motor drivers 30 years ago and I remember most of the basics.
Anyway, many thanks for the links, especialy the one leading into the Acceleration part. Pull-In- and Pull-Out-Rate I Think the terms were.

Completing the build using incremental X-, Y- and Z-encoders might be a future matter.

Lots of good code is available but my problem is to find it. You helped me a lot.

Some basic stepper motor driver is ordered in order to apply one stepper and test whether it will move my X, Y or Z accis. The hard stuff is a PROXXON MF70 that will be digitized.
