38                <h2>Getting Started</h2>
39                <p>Install Rust using rustup, the official Rust toolchain installer. It manages Rust versions and associated tools.</p>
40                
41                <pre><code>curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh</code></pre>
