What tips do you have for reading arXiv papers on Mathematics?

This could be too broad if I'm not careful, so here are some limitations on how to make the question fit:

• I'm interested in tips for reading arXiv papers with a view to understanding the latest research, both before and after peer review.
• Answers here could benefit everyone, but let's assume the reader is, like me, at the beginning of their academic career.
• Feel free to impose your own restrictions.

One obvious tip is to view the articles with a higher degree of skepticism than one from a peer reviewed journal.

Another tip is: be aware of which version of the article you are reading.
