+# Introduction
+
+  This document provides the guideline to build UEFI firmware for Qemu of LoongArch.
+
+  LoongArch is the general processor architecture of Loongson.
+
+  We can get the latest LoongArch documents or LoongArch tools at https://github.com/loongson/.
+
+# How to build (X86 Linux Environment)
+
+  1. Install LoongArch cross-tools on X86 machines.
+    Download cross-tools from https://github.com/loongson/build-tools ,Then config cross-tools env.
+    For Example:
+
+    $ wget https://github.com/loongson/build-tools/releases/download/2022.09.06/loongarch64-clfs-6.3-cross-tools-gcc-glibc.tar.xz
+    $ tar -vxf loongarch64-clfs-6.3-cross-tools-gcc-glibc.tar.xz  -C /opt
+    $ export PATH=/opt/cross-tools/bin:$PATH
+
+    Note: Please obtain the latest cross-compilation tools from https://github.com/loongson/build-tools .
+
+  2. Follow edk2-platforms/Readme.md to obtaining source code,And config build env.
+    For Example:
+
+    $ export WORKSPACE=/work/git/tianocore
+    $ mkdir -p $WORKSPACE
+    $ cd $WORKSPACE
+    $ git clone https://github.com/tianocore/edk2.git
+    $ git submodule update --init
+    $ git clone https://github.com/tianocore/edk2-platforms.git
+    $ git submodule update --init
+    $ git clone https://github.com/tianocore/edk2-non-osi.git
+    $ export PACKAGES_PATH=$PWD/edk2:$PWD/edk2-platforms:$PWD/edk2-non-osi
+
+  3. Config  cross compiler prefix.
+    For Example:
+
+    $ export GCC5_LOONGARCH64_PREFIX=loongarch64-unknown-linux-gnu-
+
+  4.Set up the build environment And  build BaseTool.
+    For Example:
+
+    $. edk2/edksetup.sh
+    $make -C edk2/BaseTools
+
+  5.Build  platform.
+    For Exmaple:
+
+    $build --buildtarget=DEBUG --tagname=GCC5 --arch=LOONGARCH64  --platform=Platform/Loongson/LoongArchQemuPkg/Loongson.dsc
+
+  After a successful build, the resulting images can be found in `Build/{Platform Name}/{TARGET}_{TOOL_CHAIN_TAG}/FV/QEMU_EFI.fd`.
+
+  A compile script is provided here:
+
+    #!/bin/bash
+    export WORKSPACE=/work/git/tianocore
+    export PACKAGES_PATH=$WORKSPACE/edk2:$WORKSPACE/edk2-platforms
+    export GCC5_LOONGARCH64_PREFIX=loongarch64-unknown-linux-gnu-
+    . edk2/edksetup.sh
+    make -C edk2/BaseTools
+    build --buildtarget=DEBUG --tagname=GCC5 --arch=LOONGARCH64  --platform=Platform/Loongson/LoongArchQemuPkg/Loongson.dsc
