Composite Higgs Models are still viable extensions of the Standard Model. I will first review the basic idea of this class of models. They explain the fact that the mass of the Higgs boson is of the order of the electroweak scale by the hypothesis that it is a pseudo Nambu Goldstone boson. I will then discuss generic aspects of Composite Higgs Models with a fermionic UV completion. We will see that realistic models contain additional pseudo Nambu Goldstone bosons, some of which are also charged with respect to SU(3). These models also predict spin 1/2 resonances, of which some have unusual color and/or charge assignments. Moreover, I will discuss to which extent existing LHC data constrain such models. This will be done first in an as much as possible model independent way using existing recast tools. In second step I will focus on a particular model to demonstrate how the bounds change due to the combination of different model sectors.
