          ### Installation

          #### Quick Install (Recommended)
          Download the wheel file below and install:
          \`\`\`bash
          pip install vocalinux-${{ steps.version.outputs.version }}-py3-none-any.whl
          \`\`\`

          #### From PyPI (Stable)
          For the latest stable release:
          \`\`\`bash
          pip install vocalinux
          \`\`\`

          #### Using Install Script
          \`\`\`bash
          curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash
          \`\`\`

          #### AppImage (no install, no root)
          Download the \`.AppImage\` matching your CPU (\`x86_64\` or \`aarch64\`) below:
          \`\`\`bash
          chmod +x Vocalinux-${{ steps.version.outputs.version }}-x86_64.AppImage
          ./Vocalinux-${{ steps.version.outputs.version }}-x86_64.AppImage
          \`\`\`
          Requires \`xdotool\`/\`wtype\`/\`ydotool\` on the host for text injection, same as the PyPI install path.
