          ```

          ### Manual Install

          Download the archive for your platform, extract, and place `pi` on your `PATH`:

          | Platform | Archive |
          |----------|---------|
          | Linux x86_64 | `pi-linux-amd64.tar.xz` |
          | Linux ARM64 | `pi-linux-arm64.tar.xz` |
          | macOS x86_64 | `pi-darwin-amd64.tar.xz` |
          | macOS ARM64 (Apple Silicon) | `pi-darwin-arm64.tar.xz` |
          | Windows x86_64 | `pi-windows-amd64.zip` |

          All archives include SHA256 checksums in `SHA256SUMS` for verification.
