Galaxy groups provide the skeleton of the cosmic web and provide the building blocks for the most massive structures in the universe. Deep X-ray surveys have opened a new observational window enabling the detection of large samples of galaxy groups. A primer for such work is the sample of X-ray detected groups in the COSMOS field. This sample spans a large range in total mass and redshift. I will show how X-ray observations complemented with a large multi- wavelength data set enables to understand the role of galaxy groups in the assembly of visible matter.
