+# Squad History Feature
+
+## Overview
+
+The squad history feature preserves historical match squad data when resetting for a new match. Previously, when the squad was reset, all player data was lost. Now it's automatically archived to a dedicated history table.
+
+## What Changed
+
+### Before
+- Squad reset would delete or overwrite previous squad data
+- No way to view who played in previous matches
+- Historical squad information was lost forever
+
+### After
+- Squad data is **automatically archived** before being cleared
+- Complete historical record preserved with match date and fixture number
+- New admin interface to view all historical squads
+- Easy lookup of who played in any previous match
+
+## How It Works
+
+### When You Reset the Squad
+
+1. **Automatic Archival**: Before clearing the current squad, the system:
+   - Copies all players to the `squad_history` table
+   - Stores the match date and fixture number
+   - Records when the archive was created
+
+2. **Clean Reset**: The current squad table is cleared for the new match
+
+3. **Confirmation**: Shows how many players were archived
+
+### Database Structure
+
+**New Table: `squad_history`**
+```sql
+- id (primary key)
+- player_number
+- player_forenames
+- player_surname
+- player_nickname
+- match_date
+- fixture_number
+- archived_at (timestamp)
+```
+
+## Using the Feature
+
+### Resetting the Squad (with History)
+
+1. Go to **Admin Dashboard** → **Match Squad Management**
+2. Click **"Reset Squad"**
+3. System automatically:
+   - Archives current squad with match details
+   - Clears squad for new match
+   - Shows confirmation message
+
+### Viewing Squad History
+
+1. Go to **Admin Dashboard** → **Squad History** 
+2. See summary of all historical squads
+3. Click **"View Details"** on any fixture to see the full squad
+4. Scroll to see detailed player lists for each match
+
+## Migration
+
+The migration has been **automatically completed**! ✅
+
+The `squad_history` table was created successfully.
+
+For future databases or if needed again:
+```bash
+python add_squad_history.py
+```
+
+## Features
+
+✅ **Automatic Archival**: No manual steps needed  
+✅ **Complete Records**: All player details preserved  
+✅ **Easy Navigation**: Summary view with drill-down details  
+✅ **Match Context**: Linked to match date and fixture number  
+✅ **Safe Reset**: Squad clearing only happens after successful archive  
+
+## Admin Interface
+
+### Squad History Page Shows:
+
+**Summary Table:**
+- Fixture Number
+- Match Date  
+- Player Count
+- Quick view button
+
+**Detailed View:**
+- Full squad rosters grouped by match
+- Player numbers, nicknames, and full names
+- Archive timestamp for audit trail
+
+## Benefits
+
+1. **Historical Reference**: See who played in any match
+2. **Team Analysis**: Track player participation over time
+3. **Data Integrity**: No more lost squad data
+4. **Audit Trail**: Know when squads were archived
+5. **Reporting**: Export or analyze squad patterns
+
+## Technical Details
+
+### Files Modified
+
+1. **`database.py`** - Added `SquadHistory` model
+2. **`main.py`** - Updated reset function and added history route
+3. **`templates/squad_history.html`** - New history viewing interface
+4. **`add_squad_history.py`** - Migration script
+
+### Safety Features
+
+- Transaction-based: Archive completes before deletion
+- Error handling: If archive fails, squad is not cleared
+- Flash messages: Clear feedback on what happened
+- Rollback capable: Can restore from history if needed
+
+## Future Enhancements
+
+Potential additions for future versions:
+- Export squad history to CSV/Excel
+- Compare squads between matches
+- Player participation statistics
+- Squad restoration from history
+- Search/filter historical squads
+- Visual squad timeline
+
+---
+
+**Implementation Date**: October 2025  
+**Status**: ✅ Active and Working
