-## 可视化快速部署
+## Visual quick deploy
 
-1. Fork NodeWarden 仓库到自己的 GitHub 账号
-2. 进入 [Cloudflare Workers & Pages](https://dash.cloudflare.com/?to=/:account/workers-and-pages/create)
-3. 选择 Continue with GitHub 并选择你的仓库
-4. 构建命令填 `npm run build`，部署命令填 `npm run deploy`
-- 如果你打算用 KV 模式，把部署命令改成 `npm run deploy:kv`
-5. 等部署完成后，打开生成的 Workers 域名
+1. Fork the NodeWarden repository to your GitHub account
+2. Open [Cloudflare Workers & Pages](https://dash.cloudflare.com/?to=/:account/workers-and-pages/create)
+3. Choose **Continue with GitHub** and select your fork
+4. Set **build command** to `npm run build` and **deploy command** to `npm run deploy`
+   - For KV mode, change the deploy command to `npm run deploy:kv`
+5. After deployment finishes, open the generated Workers URL
 
-- Workers 默认域名在部分网络环境不可直连。如需自定义域名，到 [Workers 设置](https://dash.cloudflare.com/?to=/:account/workers/services/view/nodewarden/production/settings)里添加。
+- The default Workers hostname may be unreachable on some networks. To use a custom domain, add it in [Workers settings](https://dash.cloudflare.com/?to=/:account/workers/services/view/nodewarden/production/settings).
 
-- 页面提示缺少 `JWT_SECRET` 时，到 Workers 设置里添加 Secret。正式环境至少使用 32 个字符以上的随机字符串，不要使用临时值或示例值。
+- If the site reports a missing `JWT_SECRET`, add it as a **Secret** in Workers settings. In production use a random string of at least 32 characters; do not use temporary or example values.
 
-- 这套流程里，用户实际做的是把代码交给 Cloudflare 构建并部署。代码里的 `wrangler.toml` 或 `wrangler.kv.toml` 决定绑定名，Worker 第一次处理请求时会自动初始化 D1 schema，不需要用户上传 SQL。
+- In this flow you hand code to Cloudflare to build and deploy. `wrangler.toml` or `wrangler.kv.toml` in the repo defines binding names; the Worker initializes the D1 schema on first request—no manual SQL upload.
 
 
 > [!TIP] 
-> 默认R2与可选KV的区别：
->   | 储存 | 是否需绑卡 | 单个附件/Send文件上限 | 免费额度 |
+> Default R2 vs optional KV:
+>   | Storage | Card required | Max single attachment / Send file | Free tier |
 >   |---|---|---|---|
->   | R2 | 需要 | 100 MB（软限制可更改） | 10 GB |
->   | KV | 不需要 | 25 MiB（Cloudflare限制） | 1 GB |
+>   | R2 | Yes | 100 MB (soft limit, adjustable) | 10 GB |
+>   | KV | No | 25 MiB (Cloudflare limit) | 1 GB |
 
 
-## 更新方法：
-- 手动：打开你 Fork 的 GitHub 仓库，看到顶部同步提示后，点击 `Sync fork` ➜ `Update branch`
-- 自动：进入你的 Fork 仓库 ➜ `Actions` ➜ `Sync upstream` ➜ `Enable workflow`，会在每天凌晨 3 点自动同步上游。
+## How to update
+
+- Manual: open your fork on GitHub; when the sync banner appears, click **Sync fork** → **Update branch**

-## 主要特性
 
-### PWA 渐进式 Web 应用
-
-- ✅ **可安装到桌面** - 像原生应用一样运行
-- ✅ **离线使用** - Service Worker 缓存，离线也能查看密码
-- ✅ **App 快捷方式** - 快速启动保险库、TOTP代码
-- ✅ **后台解密** - Web Worker 处理解密，不阻塞UI
-
-### Passkey 无密码登录
-
-- ✅ **WebAuthn/FIDO2 支持** - 使用指纹、Face ID等登录
-- ✅ **PRF 密钥解锁** - Passkey 可直接解锁保险库
-- ✅ **官方客户端兼容** - Chromium系浏览器扩展可用Passkey登录
-- ✅ **多设备同步** - 支持iCloud、Google Password Manager等
-
-### 云端备份说明
-
-- 远程备份支持 **WebDAV** 与 **S3**
-- 支持 **OneDrive**（通过Koofr）、**Google Drive**（通过Koofr）、**Cloudflare R2**、**Backblaze B2** 等
-- 勾选”包含附件”后：
-  - ZIP 内仍只包含 `db.json` 与 `manifest.json`
-  - 真实附件单独存放在 `attachments/`
-  - 后续备份会按稳定 blob 名复用已有附件，不会每次全量重传
-- 远程还原时：
-  - 会从 `attachments/` 目录按需读取附件
-  - 缺失的附件会被安全跳过
-  - 被跳过的附件不会在恢复后的数据库中留下脏记录
-

-| Real-time sync | ✅ | ✅ | Web, browser extension, desktop, and mobile clients stay in sync in real time |
-| Attachment upload / download | ✅ | ✅ | Cloudflare R2 or KV |
-| Send | ✅ | ✅ | Supports both text and file Sends |

-## Web Deploy
-
-1. Fork this repository. If this project helps you, consider giving it a Star.
-2. Open [Workers](https://dash.cloudflare.com/?to=/:account/workers-and-pages/create) -> `Continue with GitHub` -> select your forked repository (`NodeWarden`) -> continue.
-3. R2 is used by default. If R2 is not enabled on your account, you can use KV instead by changing the **deploy command** to `npm run deploy:kv`.
-4. Deploy and open the generated URL.
-
-| Storage | Card required | Single attachment / Send file limit | Free tier |
-|---|---|---|---|
-| R2 | Yes | 100 MB (soft limit, adjustable) | 10 GB |
-| KV | No | 25 MiB (Cloudflare limit) | 1 GB |
-
-> [!TIP]
-> How to keep your fork updated:
-> - Manual: open your fork on GitHub, click `Sync fork`, then `Update branch`
-> - Automatic: go to your fork -> `Actions` -> `Sync upstream` -> `Enable workflow`; it will sync upstream automatically every day at 3 AM
-
-## CLI Deploy
-
-```powershell
-git clone https://github.com/shuaiplus/NodeWarden.git
-cd NodeWarden
-npm install
-npx wrangler login
-
-# Default: R2 mode
-npm run deploy
-
-# Optional: KV mode
-npm run deploy:kv
-
-# Local development
-npm run dev
-npm run dev:kv
-```
-

-
-## Key Features
-
-### PWA Progressive Web App
-
-- ✅ **Install to desktop** - Runs like a native app
-- ✅ **Offline usage** - Service Worker caching, view passwords offline
-- ✅ **App shortcuts** - Quick launch vault, TOTP codes
-- ✅ **Background decryption** - Web Worker handles decryption without blocking UI
-
-### Passkey Passwordless Login
-
-- ✅ **WebAuthn/FIDO2 support** - Login with fingerprint, Face ID, etc.
-- ✅ **PRF key unlock** - Passkey can unlock vault directly
-- ✅ **Official client compatibility** - Chromium browser extension supports Passkey login
-- ✅ **Multi-device sync** - Supports iCloud, Google Password Manager, etc.
-
-### Cloud Backup Notes
-
-- Remote backup supports **WebDAV** and **S3**
-- Supports **OneDrive** (via Koofr), **Google Drive** (via Koofr), **Cloudflare R2**, **Backblaze B2**, etc.
-- When `Include attachments` is enabled:
-  - the ZIP still contains only `db.json` and `manifest.json`
-  - actual attachment files are stored separately under `attachments/`
-  - later backups reuse existing attachments by stable blob name instead of re-uploading everything every time
-- During remote restore:
-  - required attachment files are loaded from `attachments/` on demand
-  - missing attachments are skipped safely
-  - skipped attachments do not leave broken rows in the restored database
-
----
-
-## Import / Export
-
-Current supported import sources include:
-
-- Bitwarden JSON
-- Bitwarden CSV
-- Bitwarden vault + attachments ZIP
-- NodeWarden JSON
-- Multiple browser / password-manager formats available in the web import selector
-
-Current supported export formats include:
-
-- Bitwarden JSON

+| TOTP | ❌ | ✅ | 包括 `steam://` 支持 |
+| **PWA / 离线使用** | ❌ | ✅ | **可安装、离线使用、App快捷方式** |

+| 登录 2FA | ✅ | ✅ | 支持 TOTP、YubiKey、Passkey |
+| 2FA 恢复码 | ✅ | ✅ | 一次性恢复码用于禁用 2FA |
+| 实时推送同步 | ✅ | ✅ | 网页端、浏览器扩展、电脑端和手机端实时同步 |
+| 附件 / Send| ✅ | ✅ | Cloudflare R2 或 KV |
+| 导入 / 导出 | ✅ | ✅ | 支持 Bitwarden JSON / CSV / **ZIP 导入（包括附件）** |
+| **云端备份中心** | ❌ | ✅ | **支持 WebDAV / S3 定时增量备份** |
+| 设备管理 | ✅ | ✅ | **删除设备、撤销信任、永久信任** |

+
+## 可视化快速部署
+
+1. Fork NodeWarden 仓库到自己的 GitHub 账号
+2. 进入 [Cloudflare Workers & Pages](https://dash.cloudflare.com/?to=/:account/workers-and-pages/create)
+3. 选择 Continue with GitHub 并选择你的仓库
+4. 构建命令填 `npm run build`，部署命令填 `npm run deploy`
+- 如果你打算用 KV 模式，把部署命令改成 `npm run deploy:kv`
+5. 等部署完成后，打开生成的 Workers 域名
+
+- Workers 默认域名在部分网络环境不可直连。如需自定义域名，到 [Workers 设置](https://dash.cloudflare.com/?to=/:account/workers/services/view/nodewarden/production/settings)里添加。
+
+- 页面提示缺少 `JWT_SECRET` 时，到 Workers 设置里添加 Secret。正式环境至少使用 32 个字符以上的随机字符串，不要使用临时值或示例值。
+
+- 这套流程里，用户实际做的是把代码交给 Cloudflare 构建并部署。代码里的 `wrangler.toml` 或 `wrangler.kv.toml` 决定绑定名，Worker 第一次处理请求时会自动初始化 D1 schema，不需要用户上传 SQL。
+
+
+> [!TIP] 
+> 默认R2与可选KV的区别：
+>   | 储存 | 是否需绑卡 | 单个附件/Send文件上限 | 免费额度 |
+>   |---|---|---|---|
+>   | R2 | 需要 | 100 MB（软限制可更改） | 10 GB |
+>   | KV | 不需要 | 25 MiB（Cloudflare限制） | 1 GB |
+
+
+## 更新方法：
+- 手动：打开你 Fork 的 GitHub 仓库，看到顶部同步提示后，点击 `Sync fork` ➜ `Update branch`
+
+
+
+
+## CLI 部署
+
+```powershell
+git clone https://github.com/shuaiplus/NodeWarden.git
+cd NodeWarden
+
+npm install
+npx wrangler login
+
+# 默认：R2 模式
+npm run deploy
+
+# 可选：KV 模式
+npm run deploy:kv
+
+# 本地开发
+npm run dev
+npm run dev:kv
+```
