Desktop is where sift lives — Windows and Mac first, Linux beta following. Mobile is in development; wait list is open below.
校验 SHA256：下载完成后，建议用以下命令核对哈希值，确认文件没在传输中被篡改：
Verify SHA256: after downloading, verify the hash to confirm the file was not tampered with in transit:
Windows PowerShell: Get-FileHash sift-Setup.msi -Algorithm SHA256
macOS / Linux: shasum -a 256 sift-*.dmg
本页面 placeholder 占位符将在 v1.0 build 上线时更新为实际值。当前 build 占位的v0.X.X · sha256:xxxxxx不能用于校验。
Placeholder values will be replaced with real ones when v1.0 ships. The current v0.X.X · sha256:xxxxxx values cannot be used to verify.
选你的系统下载 .msi / .dmg / .AppImage，校验 SHA256（推荐）。
Pick your OS, grab the .msi / .dmg / .AppImage, verify the SHA256 (recommended).
Windows 跟向导一步步走；macOS 拖到 Applications；Linux 给 AppImage chmod +x 后双击。
Windows: follow the wizard. macOS: drag into Applications. Linux: chmod +x the AppImage and double-click.
