-# Trello Authentication Update
-
-## What Changed (January 2026)
-
-Trello moved from the simple app-key page to a Power-Up based API key system.
-
-### Old Process (Deprecated)
-- Go to https://trello.com/app-key
-- API key shown at top of page
-- Click "Token" link to generate token
-
-### New Process (Current)
-1. Go to https://trello.com/power-ups/admin
-2. Create a Power-Up (any name, e.g., "Personal Dashboard")
-3. Go to the Power-Up's **"API Key"** tab
-4. Click **"Generate a new API Key"**
-5. Copy the **API Key** (NOT the Secret - you won't use that!)
-6. In the description below the API Key, find the "testing/for-yourself" instructions
-7. Click the **"Token"** link in those instructions
-8. Click **"Allow"** to authorize
-9. Copy the token
-
-**Important Note:**
-- The API Key tab shows both an **API Key** and a **Secret**
-- For personal use, you need: **API Key + Token** (NOT Secret)
-- The Secret is only used for OAuth applications, not personal access
-- Follow the "testing" or "for-yourself" instructions to generate your token
-
-## What Stayed the Same
-
-### Authentication Method
-The actual API authentication hasn't changed:
-- Still uses API Key + Token
-- Still passed as query parameters: `?key=XXX&token=YYY`
-- No code changes needed in `internal/api/trello.go`
-
-### API Endpoints
-All Trello API endpoints remain the same:
-- Base URL: `https://api.trello.com/1`
-- `/members/me/boards` - Get user boards
-- `/boards/{id}/cards` - Get board cards
-- `/boards/{id}/lists` - Get board lists
-
-## Code Impact
-
-✅ **No code changes required**
-
-The application code already uses the correct authentication method. Only documentation needed updates.
-
-## Documentation Updated
-
-All documentation has been updated to reflect the new process:
-- ✅ `.env.example` - Updated instructions
-- ✅ `START_HERE.md` - Updated quick start
-- ✅ `QUICKSTART.md` - Updated 5-min guide
-- ✅ `README.md` - Updated installation steps
-- ✅ `SETUP_GUIDE.md` - Updated detailed setup and troubleshooting
-- ✅ `PROJECT_SUMMARY.md` - Updated quick reference
-- ✅ `CLAUDE.md` - Updated for Claude Code instances

-## Testing
-
-Authentication works the same way. Test with:
-```bash
-curl "https://api.trello.com/1/members/me/boards?key=YOUR_KEY&token=YOUR_TOKEN"
-```
-
-Should return JSON array of your boards. A 401 error means invalid credentials.
