-// Class for track/cluster acceptance selection
-// Selection in Central barrel, EMCAL and PHOS
-//
+// Class for PID selection with calorimeters
+// The Output of the 2 main methods GetPdg is a PDG number identifying the cluster,
+// being kPhoton, kElectron, kPi0 ... as defined in the header file
+// - GetPdg(const TString calo, const Double_t * pid, const Float_t energy)
+// Reads the PID weights array of the ESDs and depending on its magnitude identifies the particle
+// - GetPdg(const TString calo,const TLorentzVector mom, const AliVCluster * cluster)
+// Recalcultes PID, the bayesian or any new one to be implemented in the future
+// Right now only the possibility to recalculate EMCAL with bayesian and simple PID.
+// In order to recalculate Bayesian, it is necessary to load the EMCALUtils library
+// and do SwitchOnBayesianRecalculation().
+// To change the PID parameters from Low to High like the ones by default, use the constructor
+// AliCaloPID(flux)
+// where flux is AliCaloPID::kLow or AliCaloPID::kHigh
+// If it is necessary to change the parameters use the constructor
+// AliCaloPID(AliEMCALPIDUtils *utils) and set the parameters before.
+// - SetPIDBits: Simple PID, depending on the thresholds fDispCut fTOFCut and even the
+// result of the PID bayesian a different PID bit is set.
+//
+// All these methods can be called in the analysis you are interested.
