 # WAMR fuzz test framework

-## Install wasm-tools
-
-Download the release suitable for your specific platform from https://github.com/bytecodealliance/wasm-tools/releases/latest, unpack it, and add the executable wasm-tools to the `PATH`. Then, you should be able to verify that the installation was successful by using the following command:
+## install wasm-tools

 ```bash
+1.git clone https://github.com/bytecodealliance/wasm-tools
+$ cd wasm-tools
+2.This project can be installed and compiled from source with this Cargo command:
+$ cargo install wasm-tools
+3.Installation can be confirmed with:
 $ wasm-tools --version
-# Or learn subcommands with
+4.Subcommands can be explored with:
 $ wasm-tools help
 ```

-## Install clang Toolchain
-
-Refer to: https://apt.llvm.org/ and ensure that you have clang installed.
-
-```bash
-$ clang --version
-
-$ clang++ --version
-```
-
 ## Build

 ```bash
+mkdir build && cd build
 # Without custom mutator (libfuzzer modify the buffer randomly)
-$ cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=./clang_toolchain.cmake -DLLVM_DIR=<llvm_install_dir>/lib/cmake/llvm
-
-# TBC: if `wasm-tools mutate` is supported or not
-# Or With custom mutator (wasm-tools mutate)
-$ cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=./clang_toolchain.cmake -DLLVM_DIR=<llvm_install_dir>/lib/cmake/llvm -DCUSTOM_MUTATOR=1
-
-# Then
-$ cmake --build build
+cmake ..
+# TODO: TBC. `wasm-tools mutate` is not supported yet
+# With custom mutator (wasm-tools mutate)
+cmake .. -DCUSTOM_MUTATOR=1
+make -j$(nproc)
 ```

 ## Manually generate wasm file in build

-````bash
+```bash
 # wasm-tools smith generate some valid wasm file
 # The generated wasm file is in corpus_dir under build
 # N - Number of files to be generated
-$ ./smith_wasm.sh N
+./smith_wasm.sh N 

 # running
 ``` bash
-$ ./build/wasm-mutator/wasm_mutator_fuzz ./build/CORPUS_DIR
+cd build
+./wasm-mutate-fuzz CORPUS_DIR
 
-$ ./build/aot-compiler/aot_compiler_fuzz ./build/CORPUS_DIR
