Expected Performance of Boosted Higgs ($\rightarrow b\bar{b}$) Boson Identification with the ATLAS Detector at $\sqrt{s} = 13$ TeV

This document summarises the pre-recommendations for tagging boosted Higgs ($\rightarrow b\bar{b}$) bosons in the first Run-II data in ATLAS. The recommendations are based indirectly on a large body of work carried out in both real and simulated data from Run-I, and throughly re-evaluated and extended in simulated data at $\sqrt{s}=13$ TeV.
