            ## Installation

            ### Quick Install (Recommended)
            ```bash
            curl -fsSL https://raw.githubusercontent.com/VocaHQ/vocalinux/${{ github.ref_name }}/install.sh | bash
            ```

            ### From Source
            ```bash
            git clone https://github.com/VocaHQ/vocalinux.git
            cd vocalinux
            ./install.sh
            ```

            ### From PyPI
            ```bash
            # Install the Linux system packages first:
            # GTK/AppIndicator, PortAudio, and xdotool/wtype are required.
            python3 -m venv ~/.local/share/vocalinux-pypi/venv --system-site-packages
            source ~/.local/share/vocalinux-pypi/venv/bin/activate
            pip install vocalinux
            vocalinux
            ```

            PyPI installs the Python package only. For automatic system dependency,
            desktop integration, and model setup, use the Quick Install command above.
            See docs/INSTALL.md for distro-specific PyPI prerequisites.

            ### Arch Linux (AUR)
            ```bash
            yay -S vocalinux
            ```

            ### AppImage (no install, no root)
            Download the `.AppImage` matching your CPU (`x86_64` or `aarch64`, the latter attached
            shortly after this release is published) below:
            ```bash
            chmod +x Vocalinux-${{ steps.get_version.outputs.VERSION }}-x86_64.AppImage
            ./Vocalinux-${{ steps.get_version.outputs.VERSION }}-x86_64.AppImage
            ```
            Still requires `xdotool`/`wtype`/`ydotool` on the host for text injection, same as the PyPI path.

            ### Verifying what you downloaded
            `SHA256SUMS` covers every file here and is attached once the aarch64 build finishes,
            a few minutes after this release appears. The wheel and sdist below are the same bytes
            published to PyPI.
            ```bash
            sha256sum -c --ignore-missing SHA256SUMS
            ```
            Each artifact also carries GitHub build provenance, which ties it to this workflow run:
            ```bash
            gh attestation verify Vocalinux-${{ steps.get_version.outputs.VERSION }}-x86_64.AppImage \
              --repo ${{ github.repository }}
            ```
