=== Description of the model & references ===

Our MRSSM implementation in !FeynRules is general in the sense that it is keeping all the flavour-violating and helicity-mixing terms in the Lagrangian and also all the possible additional CP-violating phases. In order to deal in a transparent way with the more than 100 parameters, our implementation follows a set of conventions derived from those provided by the Supersymmetry Les Houches Accord.

=== Specific instructions ===

   * Only unitarity gauge is supported.
   * The flags __$CKMDiag__ and __$MNSDiag__, being set to __True__ or __False__, allow for CKM and PMNS matrices different from the identity or not. 
   * A parameter file __must__ be loaded before running the model, or all the parameters would have a value of -1 (__ReadLHAFile[Input->"myfile"]__).
