 静态源码检查之前，需要先编译出OpenArkCompiler。此后，以检查src/maple_driver源码为例，在openarkcompiler目录下执行以下命令：
 
 ```
-cp out/compile_commands.json ./
+cp output/compile_commands.json ./
 ./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/share/clang/run-clang-tidy.py -clang-tidy-binary='./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/clang-tidy' -clang-apply-replacements-binary='./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/clang-apply-replacements' src/maple_driver/
 ```
 命令说明：
 
-- `cp out/compile_commands.json ./` 将out目录之下的compile_commands.json复制到当前目录之下，它是clang-tidy运行所需要的编译命令；
+- `cp output/compile_commands.json ./` 将output目录之下的compile_commands.json复制到当前目录之下，它是clang-tidy运行所需要的编译命令；
 
 - `./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/share/clang/run-clang-tidy.py` 调用clang-tidy进行批量检查的脚本run-clang-tidy.py，其中 `./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/`目录是之前配置的clang编译器的发行包主目录； `-clang-tidy-binary` 是指明clang-tidy的具体位置； `-clang-apply-replacements-binary` 是指明run-clang-tidy.py所依赖的clang-apply-replacements的位置； `src/maple_driver/` 是要进行源码检查的目录。

+## Static code analysis
+
+This part will guide you to do the static code analysis by using the clang-tidy. After the code is changed, the static code analysis will check the coding specifications to improve the code quality.
+
+Before the static code analysis, we need compiled the OpenArkCompiler. After that, using the code of src/maple_driver as the tested directory, run the following commands in the openarkcompiler directory:
+
+```
+cp output/compile_commands.json ./
+./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/share/clang/run-clang-tidy.py -clang-tidy-binary='./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/clang-tidy' -clang-apply-replacements-binary='./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/clang-apply-replacements' src/maple_driver/
+```
+Command description:
+
+- `cp output/compile_commands.json ./`: Copy the compile_commands.json in the output directory to the openarkcompiler directory, it is required by the clang-tidy, it contains the compile commands of OpenArkCompiler.
+
+- `./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/share/clang/run-clang-tidy.py`: Call the run-clang-tidy.py which is the parallel clang-tidy runner. The `./tools/clang_llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/` directory is the directory of the release package of clang compiler. The `-clang-tidy-binary` set the path of clang-tidy binary. The `-clang-apply-replacements-binary` set the path of the clang-apply-replacements binary which is requried by the run-clang-tidy.py. The `src/maple_driver/` is the tested code directory.
