Charm decays are our only window to studying up-type quark decays and, given the amount of data we have on it, deserve a lot of attention. In this talk, I will discuss different things we can learn by looking at either hadronic or at (semi)leptonic decays. For hadronic decays, we will see how we can use arguments of the SU(3) flavour symmetry breaking of QCD to parametrise decays and make predictions, briefly discussing the prospects for CP violation. For (semi)leptonic decays, we will go through a new determination of the $V_{cs}$ CKM element in the Standard Model and the puzzles that come with it, then look for the space New Physics has of showing up in these transitions. By the end of this talk you should be convinced that there is a lot to be studied in charm decays!
