            ## Install

            **From source (requires Rust 1.94+):**
            ```
            cargo install astrid
            ```

            **Pre-built binaries:**
            Download the archive for your platform, extract, and add to PATH:
            ```
            tar xzf astrid-*-$(uname -m)-*.tar.gz
            sudo mv astrid-*/astrid astrid-*/astrid-daemon astrid-*/astrid-build /usr/local/bin/
            ```

            Then run `astrid init` to set up capsules.
