+## 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.

->   | 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`
- 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。

-| 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 |
-| Import / Export | ✅ | ✅ | Supports Bitwarden JSON / CSV / **ZIP import with attachments** |
-| **Cloud Backup Center** | ❌ | ✅ | **WebDAV / S3 scheduled backup (OneDrive/Google Drive etc.)** |
-| Password hint (web) | ⚠️ Limited | ✅ | **No email required** |
-| TOTP / Steam TOTP | ✅ | ✅ | Includes `steam://` support |

-## 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
