 Sample Wasm binaries, including "Hello World" in C, Go, and Rust, are provided in the folder. 
 These can be compiled from their respective source languages; the compilation processes are detailed in [WASI tutorial](https://github.com/bytecodealliance/wasmtime/blob/main/docs/WASI-tutorial.md#compiling-to-wasi) (C and Rust), and [WASI "Hello World" example](https://wasmbyexample.dev/examples/wasi-hello-world/wasi-hello-world.go.en-us.html) (Go).
 
+For Rust and C++ project, you can use `wasm-tools` to demangle symbol names in the `name` section. Install with `cargo install wasm-tools`. Confirm by `wasm-tools --version`. Details can be found at [Wasm Tools](https://github.com/bytecodealliance/wasm-tools).

 ## Analyze
 This section demonstrates how to use SeeWasm to analyze a generated WebAssembly file.

-build-rs: compile and demangle Wasm for Rust source programs

-USAGE:
-    build-rs [FLAGS] [PATH]
-
-FLAGS:
-    -h, --help                  Prints help information
-    -f, --file                  Build Wasm for specific Rust source file
-    -d, --dir, --directory      Build Wasm for all Rust source files in dir [DEPTH=1]
-
-PREREQUISITES:
-1. To compile Rust to Wasm, the WASI-enabled Rust toolchain must be enabled:
-   \`rustup target add wasm32-wasi\`. If you don't have \`rustup\`, follow https://rustup.rs .
-2. This script uses \`wasm-tools\` to demangle.
-   Install with \`cargo install wasm-tools\`. Confirm by \`wasm-tools --version\`.
-   Details can be found at https://github.com/bytecodealliance/wasm-tools.
