We discuss all steps necessary to obtain a consistent transition to the spontaneously broken theory and several other important aspects, including the BRST-invariance of the SMEFT action for linear $R_\\xi$-gauges. The final theory is expressed in a basis characterized by SM-like propagators for all physical and unphysical fields.
