> > +MipiSysTLib library is a upper level library consuming MIPI SYS-T
> submodule.
> > +It provides MIPI-related APIs in EDK2 format to be consumed.
> > +
> > +## MipiSysTLib Version ##
> > +EDK2 supports building with v1.1+edk2 official version which was fully
> validated.
> > +
> > +## HOW to Install MipiSysTLib for UEFI Building ##
> > +MIPI SYS-T repository was added as a submodule of EDK2 project. Please
> > +refer to edk2/Readme.md for how to clone the code.
> > +
> > +## About GenMipiSystH.py ##
> > +"GenMipiSystH.py" is a Python script which is used for customizing the
> > +mipi_syst.h.in in mipi sys-T repository. The resulting file, mipi_syst.h, 
> > will
> > +be put to same folder level as this script.
