yt-dlp/yt-dlp：README 來源編輯指南

yt-dlp/yt-dlp 的 README 將專案描述為「A feature-rich command-line audio/video downloader」。本文只整理倉庫可直接核對的內容，不把 star、Fork 或宣傳語當成品質證明。README 在「README」下寫到：yt-dlp is a feature-rich command-line audio/video downloader with support for thousands of sites.。這說明的是專案邊界，不是已完成的生產驗證。

從 README 的「UPDATE」與相關條目，可以先判斷它是否處理你的實際問題：The nightly channel offers releases that publish shortly before midnight UTC on any day that sees changes to the codebase. This channel serves as a snapshot of the project's development, and it is the recommended channel for regular users。若需求不同，不應只因專案熱度就採用。本文保留原始專案名、命令與元件名，方便回到一手來源核對。 README 另外列出一項可核對的資訊：stable is the default channel, which offers releases published on a (mostly) monthly schedule. While it is named stable due to many of its changes having been tested by users of the nightly or master release channels, the latest stable。這類原文條目可用來設計試跑步驟，但不能取代實際環境測試。

README 將運作方式分散在「Misc」等段落。可確認的線索包括：File|Description :---|:--- yt-dlp.tar.gz|GPG signature file for SHA256 sums。本文不把未寫出的架構、效能或安全邊界補成結論；真正的執行鏈仍要配合目錄、設定檔與版本標籤檢查。

第一次安裝應從 README 指出的入口開始。目前可核對的命令是： curl -L https://github.com/yt-dlp/yt-dlp/raw/master/public.key | gpg --import gpg --verify SHA2-256SUMS.sig SHA2-256SUMS gpg --verify SHA2-512SUMS.sig SHA2-512SUMS 如果倉庫沒有命令，本文不會自行編造步驟，而是建議先閱讀「RELEASE FILES」，確認系統依賴、預設埠與首次初始化。

日常使用取決於專案文件。README 的「Misc」段落提到：The public key that can be used to verify the GPG signatures is available here Example usage:。設定檔、環境變數、權限與資料目錄只在來源明確時才會記錄；沒有寫出的預設值，應在測試環境驗證並保留回滾副本。 同一部分也提到：The master channel offers "canary" releases that publish after each push to the master branch. This channel will always provide the very latest fixes and features, but may be prone to bugs or regressions.。
