 - **封面 & 预览片段** — 自动为每个视频生成封面图和预览片段，首页快速选片
-- **91 爬虫** — 内置爬虫，支持抓取 91 本月最热视频
-- **双主题** — 黑黄经典主题 / 粉白清新主题，随时切换
+- **爬虫脚本** — 项目支持导入自定义脚本，但是有一些规范，具体可以参考 [SpiderFor91](https://github.com/Just-Spider/SpiderFor91)，项目不再内置任何爬虫脚本
 - **短视频模式** — 一键切换抖音风格，沉浸刷片
-- **低资源占用** — 2C2G 服务器稳定运行，主要性能消耗就是封面图和预览视频的生成

+## PR提交规范
+欢迎大家提交PR，一起来完善这个项目，但是这里要说明一下PR提交的规范
+1. 一个PR的功能改动要单一，不建议一个PR修改了大量功能。单个PR单个功能修改，这样也更容易Merge
+2. 完善项目的PR比新增功能的PR更容易Merge（例如：例如你发现开发者没有实现爬取的视频上传到某个网盘，并且你有这个需求，此时你可以实现一下这个功能然后提交PR，也感谢你为开发者分担工作量）
+3. 新增功能的PR不容易Merge，因为某些功能的需求可能不是所有人都需要的，如果一味的不断增加功能，会让项目变得过于庞大。当然如果你肯定你的新功能和想法很好，并且相信将会对于项目有很大的改善，那么热烈欢迎你的PR
