I'm a PhD student. Just before starting my PhD I wrote up an expository paper about the basics my domain of study, in a peer-reviewed journal for graduate students, with almost no new results (the only new result is from my master's degree thesis, which is not published anywhere, and it's not groundbreaking by any means). It recently got accepted and published.
Should I list such a paper in my CV? If so, where should I put it: in the "Publications" sections (hoping that the name of the journal makes clear what kind of paper this is), or somewhere else?
If it makes any difference, this is my first and only "publication" so far (I'm in pure math, I have preprints but the review process is insanely long). On the one hand I feel like I should list it because I think I should list everything on my CV and omitting something is akin to lying by omission; but at the same time I don't want to make it seem like I'm "padding" my CV.
