documentation installation does not work

When I try to do this

wasm-tools/crates/wasm-smith/README.md

Lines 88 to 95 in e71ba20

	Install the CLI tool via `cargo`:
	```shell
	$ cargo install --git https://github.com/bytecodealliance/wasm-tools
	```
	Convert some arbitrary input into a valid Wasm module:

then this message is appear:

$ cargo install --git https://github.com/bytecodealliance/wasm-tools wasm-smith
    Updating git repository `https://github.com/bytecodealliance/wasm-tools`
error: there is nothing to install in `wasm-smith v0.11.4 (https://github.com/bytecodealliance/wasm-tools#e71ba20d)`, because it has no binaries
`cargo install` is only for installing programs, and can't be used with libraries.
To use a library crate, add it as a dependency in a Cargo project instead.

Ah those instructions need to be updated, they should recommend cargo install wasm-tools and usage is wasm-tools smith ....

Would you be up for sending a PR to udpate the instructions?

when I excuted cargo install wasm-tools , I got the error below:

Hi @Lost-Temple. array::from_fn was stabilized in 1.63.0, released a few weeks back.

My guess is you need to update your Rust toolchain to the latest version to install wasm-tools with the latest dependencies or, alternatively, install with the --locked option to use force cargo to use the versions from the lock file.

thx, it worked.

1. rustup update stable --no-self-update && rustup default stable
2. cargo install wasm-tools

thank you very much
