  We revisit the construction of the composite Higgs models in a context of the
bottom-up holographic approach. The soft wall framework is under consideration
imposing the translation of the $4D$ global symmetry breaking characteristic to
the new strongly interacting sector in the $5D$ bulk. The focus stays on the
minimal $SO(5)\to SO(4)$ breaking pattern. The $5D$ model has a specific form
inspired by the effective models of QCD, representing a generalized sigma model
coupled both to the composite resonances and to the SM gauge bosons. The latter
are treated as external $4D$ sources and conceptually develop no propagation
into the bulk. The holographic description allows for the consideration of spin
one and spin zero resonances. The resulting spectrum leads in a natural way to
a variety of new composite resonances, four of which represent the massless
Goldstone bosons. Existing experimental constraints on the electroweak
precision parameters permit to accommodate vector and scalar resonances with
masses in the $1 - 2$ TeV range without difficulties, but higher masses are
possible too. Moreover, for the SM gauge fields holography provides relevant
vacuum polarization amplitudes and mixing with composite resonances. Further
considering higher order correlation functions we can formulate
semi-quantitative predictions for the effective couplings and cross-sections.
These provide additional restrictions that are currently being investigated.
