+## Introduction of MipiSysTLib ##
+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.
+```
+ mipisyst submodule MipiSysTLib library
+|---------------------| GenMipiSystH.py |---------------------|
+| mipi_syst.h.in |-----------------> | mipi_syst.h |
+|---------------------| |---------------------|
+```
+This script needs to be done once by a developer when adding some
+project-related definition or a new version of mipi_syst.h.in was released.
+Normal users do not need to do this, since the resulting file is stored
+in the EDK2 git repository.
