 On Windows the binary is `target\release\recall.exe`; copy it somewhere on
 `PATH`. Make sure the install directory is on `PATH`.
 
+### Update
+
+```sh
+recall update
+```
+
+`recall update` downloads the latest stable GitHub Release for the current
+platform, shows download progress, verifies its SHA-256 checksum, and replaces
+the running binary. Use `recall update --check` to check without installing.
+The history TUI checks for stable updates at most once every 24 hours and shows
+an available update in its status bar.

+### 更新
+
+```sh

+`recall update` 会下载当前平台的最新稳定版 GitHub Release，展示下载进度、校验
+SHA-256，然后替换正在运行的二进制。使用 `recall update --check` 仅检查更新。
