 ## 简介
 
 > [!NOTE]
-> 此为 v2.x 版本文档，v1.x 版本文档请前往[此处](https://github.com/amtoaer/bili-sync/tree/v1.x)查看。
-
-
-为 NAS 用户编写的 BILIBILI 收藏夹同步工具，可使用 EMBY 等媒体库工具浏览。
-
-支持展示视频封面、名称、加入日期、标签、分页等。
+> [点击此处](https://bili-sync.allwens.work/)查看文档
 
+bili-sync 是一款专为 NAS 用户编写的哔哩哔哩同步工具，由 Rust & Tokio 驱动。
 
 ## 效果演示
 
-**注：因为可能同时存在单页视频和多页视频，媒体库类型请选择“混合内容”。**

-## 配置文件说明
 
-> [!NOTE]
-> 在 Docker 环境中，`~` 会被展开为 `/app`。
+## 功能与路线图
 
-程序默认会将配置文件存储于 `~/.config/bili-sync/config.toml`，数据库文件存储于 `~/.config/bili-sync/data.sqlite`，如果发现不存在会新建并写入默认配置。
+- [x] 使用用户填写的凭据认证，并在必要时自动刷新
+- [x] 支持收藏夹与视频列表/视频合集的下载
+- [x] 自动选择用户设置范围内最优的视频和音频流，并在下载完成后使用 FFmpeg 合并
+- [x] 使用 Tokio 与 Reqwest，对视频、视频分页进行异步并发下载
+- [x] 使用媒体服务器支持的文件命名，方便一键作为媒体库导入
+- [x] 当前轮次下载失败会在下一轮下载时重试，失败次数过多自动丢弃
+- [x] 使用数据库保存媒体信息，避免对同个视频的多次请求
+- [x] 打印日志，并在请求出现风控时自动终止，等待下一轮执行
+- [x] 提供多平台的二进制可执行文件，为 Linux 平台提供了立即可用的 Docker 镜像
+- [x] 支持对“稍后再看”内视频的自动扫描与下载
+- [x] 支持对 UP 主投稿视频的自动扫描与下载
+- [x] 支持限制任务的并行度和接口请求频率
+- [x] 支持单个文件的分块并行下载
+- [x] 支持使用 Web UI 配置，查看并管理视频、视频源
 
-配置文件加载时会进行简单校验，默认配置无法通过校验，程序会报错终止运行。
-
-可以下载程序后直接运行程序，看到报错后参考报错信息对默认配置进行修改，修改正确后即可正常运行。
-
-对于配置文件中的 `credential`，请参考[凭据获取流程](https://nemo2011.github.io/bilibili-api/#/get-credential)。
-
-配置文件中的 `video_name` 和 `page_name` 支持使用模板，模板的替换语法请参考示例。模板中的内容在执行时会被动态替换为对应的内容。
-
-video_name 支持设置 bvid（视频编号）、title（视频标题）、upper_name（up 主名称）、upper_mid（up 主 id）。
-
-page_name 除支持 video 的全部参数外，还支持 ptitle（分 P 标题）、pid（分 P 页号）。
-
-对于每个 favorite_list 的下载路径，程序会在其下建立如下的文件夹：
-
-1. 单页视频：
-
-    ```bash
-    ├── {video_name}
-    │   ├── {page_name}.mp4
-    │   ├── {page_name}.nfo
-    │   └── {page_name}-poster.jpg
-    ```
-
-2. 多页视频：
-
-    ```bash
-    ├── {video_name}
-    │   ├── poster.jpg
-    │   ├── Season 1
-    │   │   ├── {page_name} - S01E01.mp4
-    │   │   ├── {page_name} - S01E01.nfo
-    │   │   ├── {page_name} - S01E01-thumb.jpg
-    │   │   ├── {page_name} - S01E02.mp4
-    │   │   ├── {page_name} - S01E02.nfo
-    │   │   └── {page_name} - S01E02-thumb.jpg
-    │   └── tvshow.nfo
-    ```
-
-对于 filter_option 的可选值，请前往 [analyzer.rs](https://github.com/amtoaer/bili-sync/blob/main/src/bilibili/analyzer.rs) 查看。
-
-对于 danmaku_option 的项含义，请前往 [danmaku/mod.rs](https://github.com/amtoaer/bili-sync/blob/main/src/bilibili/danmaku/canvas/mod.rs) 与 [原项目的说明](https://github.com/gwy15/danmu2ass?tab=readme-ov-file#%E5%91%BD%E4%BB%A4%E8%A1%8C) 查看。

-```
-
-## Docker Compose 文件示例
-
-该项目为 `Linux/amd64` 与 `Linux/arm64` 提供了 Docker 版本镜像。
-
-Docker 版包含该平台对应版本的可执行文件（位于`/app/bili-sync-rs`），并预装了 FFmpeg，其它用法与普通版本完全一致。（可查看 [用于构建镜像的 Dockerfile](./Dockerfile) ）
-
-以下是一个 Docker Compose 的编写示例：
-```yaml
-services:
-  bili-sync-rs:
-    image: amtoaer/bili-sync-rs:v2.0.0
-    restart: unless-stopped
-    network_mode: bridge
-    tty: true  # 该选项请仅在日志终端支持彩色输出时启用，否则日志中可能会出现乱码
-    hostname: bili-sync-rs
-    container_name: bili-sync-rs
-    volumes:
-      - /home/amtoaer/.config/nas/bili-sync-rs:/app/.config/bili-sync
-      # 以及一些其它必要的挂载，确保此处的挂载与 bili-sync-rs 的配置相匹配
-      # ...
-    logging:
-      driver: "local"
-```
-
