+- Introduction
+
+  LoongArch is the general processor architecture of Loongson.
+
+  The following versions of the LoongArch core are supported
+    core: 3A5000
+    https://github.com/loongson/LoongArch-Documentation/releases/download/2021.08.17/LoongArch-Vol1-v1.00-EN.pdf
+
+  We can get the latest loongarch documents at https://github.com/loongson/LoongArch-Documentation/tags.
+
+
+- Linux-user emulation
+
+  We already support Linux user emulation. We can use LoongArch cross-tools to build LoongArch executables on X86 machines,
+  and We can also use qemu-loongarch64 to run LoongArch executables.
+
+  1. Install LoongArch cross-tools on X86 machines.
+
+    Download cross-tools.
+
+      wget https://github.com/loongson/build-tools/releases/latest/download/loongarch64-clfs-20210831-cross-tools.tar.xz
+
+      tar -vxf loongarch64-clfs-20210831-cross-tools.tar.xz -C /opt
+
+    Config cross-tools env.
+
+      . setenv.sh
+
+      setenv.sh:
+
+          #!/bin/sh
+          set -x
+          CC_PREFIX=/opt/cross-tools
+
+          export PATH=$CC_PREFIX/bin:$PATH
+          export LD_LIBRARY_PATH=$CC_PREFIX/lib:$LD_LIBRARY_PATH
+          export LD_LIBRARY_PATH=$CC_PREFIX/loongarch64-unknown-linux-gnu/lib/:$LD_LIBRARY_PATH
+          set +x
+
+  2. Test tests/tcg/multiarch.
+
+    ./configure --disable-rdma --disable-pvrdma --prefix=/usr  \
+            --target-list="loongarch64-linux-user"  \
+            --disable-libiscsi --disable-libnfs --disable-libpmem \
+            --disable-glusterfs --enable-libusb --enable-usb-redir \
+            --disable-opengl --disable-xen --enable-spice --disable-werror \
+            --enable-debug --disable-capstone --disable-kvm --enable-profiler
+
+    cd  build/
+
+    make && make check-tcg
+
+  3. Run LoongArch system basic command with loongarch-clfs-system.
+
+    Download clfs-system.
+
+      wget https://github.com/loongson/build-tools/releases/latest/download/loongarch64-clfs-system-2021-08-31.tar.bz2
+
+      tar -vxf loongarch64-clfs-system-2021-08-31.tar.bz2 -C /opt/clfs
+
+    Config env.
+
+      cp /opt/clfs/lib64/ld-linux-loongarch64.so.1   /lib64
+
+      export LD_LIBRARY_PATH="/opt/clfs/lib64"
+
+    Run LoongArch system basic command.
+
+      ./qemu-loongarch64  /opt/clfs/usr/bin/bash
+      ./qemu-loongarch64  /opt/clfs/usr/bin/ls
+      ./qemu-loongarch64  /opt/clfs/usr/bin/pwd
+      ...
+
+
+- Note.
+  We can get the latest LoongArch documents or LoongArch tools at https://github.com/loongson/
