# Install rust

Rust is the main programming language used for CosmWasm smart contracts. While WASM smart contracts can theoretically be written in any programming language, CosmWasm libraries and tooling work best with Rust.

First, [**install rustup**](https://rustup.rs/).

Then run the following commands:

```bash
# 1. Set 'stable' as the default release channel:
rustup default stable
cargo version
# If this is lower than 1.50.0+, update
rustup update stable

# 2. Add WASM as the compilation target:
rustup target list --installed
rustup target add wasm32-unknown-unknown

# 3. Install the following packages to generate the contract:
cargo install cargo-generate --features vendored-openssl
cargo install cargo-run-script
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bitsong.io/features-and-modules/cosmwasm/install-rust.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
