+Both wasm binary file and AOT file are supported by iwasm. The wamrc AOT compiler is to compile wasm binary file to AOT file which can also be run by iwasm. You can execute following commands to build **wamrc** compiler:
+
+For **Linux**(Ubuntu 20.04 as an example):
+
+First, make sure necessary dependency are installed:
+
+```shell
+sudo apt-get install git build-essential cmake g++-multilib libgcc-9-dev lib32gcc-9-dev ccache 
+```
+
+```shell
+cd wamr-compiler
+./build_llvm.sh (or "./build_llvm_xtensa.sh" to support xtensa target)
+mkdir build && cd build
+cmake .. (or "cmake .. -DWAMR_BUILD_PLATFORM=darwin" for MacOS)
+make
+# wamrc is generated under current directory
+```
+
+For **Windows**：
+
+```shell
+cd wamr-compiler
+python build_llvm.py
+mkdir build && cd build
+cmake ..
+cmake --build . --config Release
+# wamrc.exe is generated under .\Release directory
