Crack Me Material

Question

I'd like to get started with reverse engineering.

Several years ago I saw many programs called crackmes, to crack.

When I searched for some this week, I found none.

My question is, can somebody recommend some websites (like crackme walkthroughs) or learning resources to get started with reverse engineering?

Although this is an old posting, I would like to add a long-standing still active site with great challenges (sometimes pretty pretty hard, in the higher levels): https://overthewire.org/wargames/
