I am looking for a simple and natural way to express the process of getting familiar with something.

Some options I've been considering include

I am acquainting myself with something.

I am getting familiar with something.

I am getting acquainted with something.

I am making myself familiar with something.

All the sentences are in Present Progressive because it seems to me like a reasonable way to express a continuing action. Also, I am wondering if Present Simple can be used.

Thank you.
