Studies of galaxy clusters have played an important role in helping to establish the standard model of cosmology, with a universe dominated by dark matter and dark energy. I will summarize the latest results on cosmology from cluster studies, highlighting the role of X-ray measurements. The prospects for progress over the coming decade are outstanding with new catalogs, hundreds of times larger, being constructed across a variety of wavelengths. Extracting the full cosmological information from these catalogs will not be trivial, however, requiring a coordinated approach that combines multi-wavelength survey data, targeted follow-up observations and tailored simulations. I will highlight several ways in which to help make these contributions as impactful as possible.
