# Installation Follow the steps to set up a local development chain or connect to the Source Chain Testnet before continuing. ## Rust Assuming you have never worked with rust, you will first need to install some tooling. The standard approach is to use `rustup` to maintain dependencies and handle updating multiple versions of `cargo` and `rustc`, which you will be using. ### Installing Rust in Linux and Mac First, [install rustup (opens new window)](https://rustup.rs/). Once installed, make sure you have the wasm32 target: ``` rustup default stable cargo version # If this is lower than 1.49.0+, update rustup update stable rustup target list --installed rustup target add wasm32-unknown-unknown ``` --- # Agent Instructions: 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: ``` GET https://docs.sourceprotocol.io/smart-contracts-and-sourced-development/cw-20-erc-20-tutorial/installation.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
