+# Introduction
+
+## EDK2 RISC-V Platform Package
+RISC-V platform package provides the generic and common modules for RISC-V platforms. RISC-V platform package could include RiscPlatformPkg.dec to use the common drivers, libraries, definitions, PCDs and etc. for the platform development.
+
+## EDK2 RISC-V Platforms
+RISC-V platform is created and maintained by RISC-V platform vendors. The directory of RISC-V platform should be created under Platform/RiscV. Vendor should create the folder under Platform/RiscV and name it using vendor name, under the vendor folder is the platform folder named by platform model name, code name or etc. (e.g. Platform/RiscV/SiFive/U500Pkg)
+
+## Build EDK2 RISC-V Platforms
+RISC-V platform package should provide EDK2 metafiles under RISC-V platform package folder (Platform/RiscV/{Vendor}/{Platform}). Build RISC-V platform package against edk2 and follow the build guidence mentioned in Readme.md under below link.<br>
+https://github.com/tianocore/edk2-platforms<br>
+
+### Download the sources ###
+```
+git clone https://github.com/tianocore/edk2-staging.git
+# Checkout RISC-V-V2 branch
+git clone https://github.com/tianocore/edk2-platforms.git
+# Checkout devel-riscv-v2 branch
+git clone https://github.com/tianocore/edk2-non-osi.git
+```
+
+### Requirements
+Build EDK2 RISC-V platform requires GCC RISC-V toolchain. Refer to https://github.com/riscv/riscv-gnu-toolchain for the details.
+The commit ID 64879b24 is verified to build RISC-V EDK2 platform and boot to EFI SHELL successfully.
+
+### EDK2 project
+Currently, the EDK2 RISC-V platform can only build with edk2 project in **edk2-staging/RISC-V-V2** branch. The build architecture whcih is supported and verified so far is "RISCV64". The verified RISC-V toolchain is https://github.com/riscv/riscv-gnu-toolchain @64879b24, toolchain tag is "GCCRISCV" declared in tools_def.txt<br>
+
+### Linux Build Instructions
+You can build the RISC-V platform using below script, <br>
+`build -a RISCV64 -p Platform/{Vendor}/{Platform}/{Platform}.dsc -t GCCRISCV`
+
+Or modify target.txt to set up your build parameters.
+
+## RISC-V Platform PCD settings

+|PcdPlatformFlashNvStorageFtwWorkingBase| The base address of EFI variable fault tolerance worksapce (FTW) within firmware device|
+|PcdPlatformFlashNvStorageFtwSpareBase| The base address of EFI variable spare FTW within firmware device|
+
+### RISC-V Physical Memory Protection (PMP) Region Settings
+Below PCDs could be set in platform FDF file.
+
+| **PCD name** |**Usage**|
+|----------------|----------|
+|PcdFwStartAddress| The starting address of firmware region to protected by PMP|
+|PcdFwEndAddress| The ending address of firmware region to protected by PMP|
+
+### RISC-V Processor HART Settings
+
+| **PCD name** |**Usage**|
+|----------------|----------|
+|PcdHartCount| Number of RISC-V HARTs, the value is processor-implementation specific|
+|PcdBootHartId| The ID of RISC-V HART to execute main fimrware code and boot system to OS|
+
+### RISC-V OpenSBI Settings
+
+| **PCD name** |**Usage**|
+|----------------|----------|
+|PcdScratchRamBase| The base address of OpenSBI scratch buffer for all RISC-V HARTs|
+|PcdScratchRamSize| The total size of OpenSBI scratch buffer for all RISC-V HARTs|
+|PcdOpenSbiStackSize| The size of initial stack of each RISC-V HART for booting system use OpenSBI|
+|PcdTemporaryRamBase| The base address of temporary memory for PEI phase|
+|PcdTemporaryRamSize| The temporary memory size for PEI phase|
+
+## Supported Operating Systems
+Only support to boot to EFI Shell so far
+
+## Known Issues and Limitations
+Only RISC-V RV64 is verified
