Update MD

Create or update project documentation in Markdown. Use when building a new project doc set, updating existing docs after a deploy or feature change, or establishing a doc structure for a new project. Covers doc splitting, update rules, naming conventions, and the standard file map pattern used across all projects (TPMS, TonicLab, etc.).

Core Principles

1. Split, don't consolidate — One file per concern. Never dump everything into one doc.
2. Overview is always the entry point — Every project has a PROJECT-OVERVIEW.md that's lean and links to everything else.
3. 按需讀取 — Detail files are only read when needed; keep them out of the overview.
4. Update rules are mandatory — Every doc set must define when each file should be updated.
5. Deploy = Update docs — Docs update immediately after every deploy. No exceptions.

Standard Doc Set Structure

Every project follows this pattern:

PROJECT-OVERVIEW.md     ← 精簡總覽，每 session 必讀
PROJECT-DEPLOY.md       ← 部署、Docker、Nginx、SSL、環境變數
PROJECT-APPS.md         ← 功能規格（如有多個 app/module）
PROJECT-DB.md           ← 數據庫 schema 及連接設定
PROJECT-HISTORY.md      ← 版本日誌，每次 deploy 後更新

Add or remove files based on project complexity. See references/doc-templates.md for file templates.

OVERVIEW.md Must-Haves

• Project name, domain/URL, status, VM/hosting info
• Feature/tool status table (✅ / 🔄 / ⏳ / ❌)
• Doc map table (file → content)
• Update rules table (change type → files to update)
• Current version number

Update Rules (include in every OVERVIEW.md)

改動類型	需要更新
新功能 / 改功能	OVERVIEW（狀態）+ APPS
新版本發布	HISTORY + OVERVIEW（版本號）
部署/基礎設施改動	DEPLOY
DB schema 改動	DB

Status Symbols

Use consistently across all docs:

• ✅ 完成
• 🔄 進行中
• ⏳ 待開始
• ❌ 取消 / 廢棄

When Updating Docs

1. Identify which files are affected by the change (use the update rules table)
2. Update only those files — don't touch unrelated docs
3. Update version number in OVERVIEW if it's a release
4. Add entry to HISTORY with date, version, and bullet points

Creating a New Doc Set

1. Create PROJECT-OVERVIEW.md first — establish the doc map before writing detail files
2. Add detail files as needed (DEPLOY, APPS, DB, HISTORY)
3. Add the doc map to the project's AGENTS.md so agents know which files exist
4. Reference references/doc-templates.md for boilerplate
