        # ZeroTier One Alpine Linux Build

        **Version:** \`$ZEROTIER_VERSION\`  
        **Architecture:** \`$(uname -m)\`  
        **Built on:** \`$(date -u +"%Y-%m-%d %H:%M:%S UTC")\`  
        **Alpine Version:** \`$(cat /etc/alpine-release)\`

        ## Installation Instructions

        1. Download the package:
           \`\`\`bash
           wget "$FORGEJO_URL/api/packages/${{ github.repository_owner }}/generic/zerotier-one-alpine/$ZEROTIER_VERSION/$PACKAGE_FILE"
           \`\`\`

        2. Verify checksum (optional):
           \`\`\`bash
           wget "$FORGEJO_URL/api/packages/${{ github.repository_owner }}/generic/zerotier-one-alpine/$ZEROTIER_VERSION/$PACKAGE_FILE.sha256"
           sha256sum -c "$PACKAGE_FILE.sha256"
           \`\`\`

        3. Extract and install:
           \`\`\`bash
           tar -xzf "$PACKAGE_FILE"
           sudo cp -r zerotier-one-alpine/* /
           sudo chmod +x /etc/init.d/zerotier-one
           sudo rc-update add zerotier-one default
           sudo rc-service zerotier-one start
           \`\`\`

        4. Check status:
           \`\`\`bash
           sudo rc-service zerotier-one status
           zerotier-cli status
           \`\`\`
