The tau-lepton plays an important role in the physics program at LHC. Itsspin can be used for separation of signal from background or in measuringproperties of New Particles decaying to tau leptons.  The TauSpinner package represents a tool to modify tau spin effects in anysample containing tau leptons. Generated events, featuring taus produced fromintermediate state W, Z, H bosons can be used as an input. The information onthe polarization and spin correlations is reconstructed from the kinematics ofthe tau lepton(s) (nutau in case of W-mediated processes) and tau decayproducts. By weights, attributed on the event-by-event basis, it enablesnumerical evaluation and/or modification of the spin effects.  We review distributions to monitor spin effects in leptonic and hadronic taudecays with up to three pions, to provide benchmarks for validation of spincontent of the event sample and to visualize the tau lepton spin polarizationand correlation effects. The demonstration examples for use of TauSpinnerlibraries, are documented. New validation methods of such an approach areprovided. Other topics, like TauSpinner systematic errors or sensitivity ofexperimental distributions to spin, are addressed in part only.  This approach is of interest for implementation of spin effects in embeddedtau lepton samples, where Z to mu mu events from data of muons are replaced bysimulated tau leptons. Embedding is used at LHC for estimating Z to tau taubackground to H to tau tau signatures.
