-### Database
+### Database Migrations
+
+**oslstats uses Bun's migration framework for safe, incremental schema changes.**
+
+#### Quick Reference
+
 ```bash
-# Run migrations
+# Show migration status
+make migrate-status
+
+# Preview pending migrations (dry-run)
+make migrate-dry-run
+
+# Run pending migrations (with automatic backup)
 make migrate
-# OR
+
-./bin/oslstats --migrate
+# Rollback last migration group
+make migrate-rollback
+
+# Create new migration
+make migrate-create NAME=add_email_to_users
+
+# Dev: Run migrations without backup (faster)
+make migrate-no-backup
+
+# Dev: Reset database (DESTRUCTIVE - deletes all data)
+make reset-db
 ```
 
+#### Creating a New Migration
+
+**Example: Adding an email field to users table**
+
+1. **Generate migration file:**
+   ```bash
+   make migrate-create NAME=add_email_to_users
+   ```
+   Creates: `cmd/oslstats/migrations/20250124150030_add_email_to_users.go`
+
+2. **Edit the migration file:**
+   ```go
+   package migrations
+   
+   import (
+       "context"
+       "github.com/uptrace/bun"
+   )
+   
+   func init() {
+       Migrations.MustRegister(
+           // UP: Add email column
+           func(ctx context.Context, db *bun.DB) error {
+               _, err := db.ExecContext(ctx, 
+                   "ALTER TABLE users ADD COLUMN email VARCHAR(255)")
+               return err
+           },
+           // DOWN: Remove email column (for rollback)
+           func(ctx context.Context, db *bun.DB) error {
+               _, err := db.ExecContext(ctx, 
+                   "ALTER TABLE users DROP COLUMN email")
+               return err
+           },
+       )
+   }
+   ```
+
+3. **Update the model** (`internal/db/user.go`):
+   ```go
+   type User struct {
+       bun.BaseModel `bun:"table:users,alias:u"`
+       
+       ID        int    `bun:"id,pk,autoincrement"`
+       Username  string `bun:"username,unique"`
+       Email     string `bun:"email"`          // NEW FIELD
+       CreatedAt int64  `bun:"created_at"`
+       DiscordID string `bun:"discord_id,unique"`
+   }
+   ```
+
+4. **Preview the migration (optional):**
+   ```bash
+   make migrate-dry-run
+   ```
+   Output:
+   ```
+   [INFO] Pending migrations (dry-run):
+     📋 20250124150030_add_email_to_users
+   [INFO] Would migrate to group 2
+   ```
+
+5. **Apply the migration:**
+   ```bash
+   make migrate
+   ```
+   Output:
+   ```
+   [INFO] Step 1/5: Validating migrations...
+   [INFO] Migration validation passed ✓
+   [INFO] Step 2/5: Checking for pending migrations...
+   [INFO] Step 3/5: Creating backup...
+   [INFO] Backup created: backups/20250124_150145_pre_migration.sql.gz (2.3 MB)
+   [INFO] Step 4/5: Acquiring migration lock...
+   [INFO] Migration lock acquired
+   [INFO] Step 5/5: Applying migrations...
+   [INFO] Migrated to group 2
+     ✅ 20250124150030_add_email_to_users
+   [INFO] Migration lock released
+   ```
+
+#### Migration Patterns
+
+**Create Table:**
+```go
+// UP
+_, err := db.NewCreateTable().
+    Model((*db.Game)(nil)).
+    Exec(ctx)
+return err
+
+// DOWN
+_, err := db.NewDropTable().
+    Model((*db.Game)(nil)).
+    IfExists().
+    Exec(ctx)
+return err
+```
+
+**Add Column:**
+```go
+// UP
+_, err := db.ExecContext(ctx, 
+    "ALTER TABLE users ADD COLUMN email VARCHAR(255)")
+return err
+
+// DOWN
+_, err := db.ExecContext(ctx, 
+    "ALTER TABLE users DROP COLUMN email")
+return err
+```
+
+**Create Index:**
+```go
+// UP
+_, err := db.NewCreateIndex().
+    Model((*db.User)(nil)).
+    Index("idx_username").
+    Column("username").
+    Exec(ctx)
+return err
+
+// DOWN
+_, err := db.ExecContext(ctx, 
+    "DROP INDEX IF EXISTS idx_username")
+return err
+```
+
+**Data Migration:**
+```go
+// UP
+_, err := db.NewUpdate().
+    Model((*db.User)(nil)).
+    Set("status = ?", "active").
+    Where("status IS NULL").
+    Exec(ctx)
+return err
+
+// DOWN (if reversible)
+_, err := db.NewUpdate().
+    Model((*db.User)(nil)).
+    Set("status = NULL").
+    Where("status = ?", "active").
+    Exec(ctx)
+return err
+```
+
+#### Safety Features
+
+✅ **Automatic Backups**
+- Compressed with gzip (saves ~80% space)
+- Created before every migration and rollback
+- Stored in `backups/` directory
+- Retention policy keeps last 10 backups
+- Graceful fallback if `pg_dump` not installed
+
+✅ **Migration Locking**
+- PostgreSQL advisory locks prevent concurrent migrations
+- 5-minute timeout prevents hung locks
+- Safe for multi-instance deployments
+
+✅ **Validation**
+- Pre-migration `go build` check ensures migrations compile
+- Dry-run mode previews changes without applying
+- Status command shows exactly what's applied
+
+✅ **Rollback Support**
+- Every migration must have a DOWN function
+- Rollbacks are grouped (undo last batch together)
+- Automatic backup before rollback
+
+#### Environment Variables
+
+```bash
+# Backup directory (default: backups)
+DB_BACKUP_DIR=backups
+
+# Number of backups to keep (default: 10)
+DB_BACKUP_RETENTION=10
+```
+
+#### Troubleshooting
+
+**"pg_dump not found"**
+- Migrations will still run, but backups will be skipped
+- Install PostgreSQL client tools for backups:
+  ```bash
+  # Ubuntu/Debian
+  sudo apt-get install postgresql-client
+  
+  # macOS
+  brew install postgresql
+  
+  # Arch
+  sudo pacman -S postgresql-libs
+  ```
+
+**"migration already in progress"**
+- Another instance is running migrations
+- Wait for it to complete (max 5 minutes)
+- If stuck, check for hung database connections
+
+**"migration build failed"**
+- Migration file has syntax errors
+- Fix the errors and try again
+- Use `go build ./cmd/oslstats/migrations` to debug
+
+#### Best Practices
+
+1. **Always test in development first**
+   - Use `make migrate-dry-run` to preview
+   - Test rollback: `make migrate-rollback`
+   - Verify with `make migrate-status`
+
+2. **Write reversible migrations**
+   - DOWN function should undo UP changes
+   - Test rollbacks work correctly
+   - Some operations (data deletion) may not be reversible
+
+3. **Keep migrations focused**
+   - One migration = one logical change
+   - Don't mix schema changes with data migrations
+   - Use descriptive names
+
+4. **Production checklist**
+   - ✅ Tested in development
+   - ✅ Tested rollback
+   - ✅ Verified backup works
+   - ✅ Communicated downtime (if any)
+   - ✅ Have rollback plan ready
+
+5. **Development workflow**
+   - Use `--no-backup` for speed: `make migrate-no-backup`
+   - Use `--reset-db` to start fresh (loses data!)
+   - Commit migrations to version control
+

+
+## 🚀 Quick Start Guide
+
+### First Time Setup
+
+1. **Ensure PostgreSQL is running**
+   ```bash
+   # Your database should be configured in .env:
+   # DB_USER=...
+   # DB_PASSWORD=...
+   # DB_HOST=localhost
+   # DB_PORT=5432
+   # DB_NAME=oslstats
+   # DB_SSL=disable
+   ```
+
+2. **Run initial migration**
+   ```bash
+   make migrate
+   ```
+   This will:
+   - Validate migrations compile
+   - Create initial schema (users, discord_tokens tables)
+   - Create migration tracking table (bun_migrations)
+
+3. **Verify**
+   ```bash
+   make migrate-status
+   ```
+   Should show:
+   ```
+   ✅ Applied  20250124000001_initial_schema  1  2026-01-24 15:XX:XX
+   ```
+
+### Adding Your First Feature
+
+1. **Create a migration**
+   ```bash
+   make migrate-create NAME=add_games_table
+   ```
+
+2. **Edit the generated file**
+   - Location: `cmd/oslstats/migrations/YYYYMMDDHHmmss_add_games_table.go`
+   - Implement UP function (apply changes)
+   - Implement DOWN function (rollback changes)
+
+3. **Preview**
+   ```bash
+   make migrate-dry-run
+   ```
+
+4. **Apply**
+   ```bash
+   make migrate
+   ```
+
+5. **Verify**
+   ```bash
+   make migrate-status
+   ```
+
+## 🛡️ Safety Features in Action
+
+### 1. Automatic Backups
+Every migration creates a compressed backup:
+```
+backups/20250124_150530_pre_migration.sql.gz (2.5 MB)
+```
+
+### 2. Migration Locking
+```
+[INFO] Migration lock acquired
+[INFO] Applying migrations...
+[INFO] Migration lock released
+```
+
+### 3. Validation
+```
+[INFO] Step 1/5: Validating migrations...

+## 📝 Example: Adding Email Field to Users
+
+**Complete workflow:**
+
+```bash
+# 1. Create migration
+make migrate-create NAME=add_email_to_users
+
+# 2. Edit cmd/oslstats/migrations/YYYYMMDDHHmmss_add_email_to_users.go
+# Add this code:
+
+package migrations
+
+import (
+    "context"
+    "github.com/uptrace/bun"
+)
+
+func init() {
+    Migrations.MustRegister(
+        // UP: Add email column
+        func(ctx context.Context, db *bun.DB) error {
+            _, err := db.ExecContext(ctx, 
+                "ALTER TABLE users ADD COLUMN email VARCHAR(255)")
+            return err
+        },
+        // DOWN: Remove email column
+        func(ctx context.Context, db *bun.DB) error {
+            _, err := db.ExecContext(ctx, 
+                "ALTER TABLE users DROP COLUMN email")
+            return err
+        },
+    )
+}
+
+# 3. Update internal/db/user.go model
+# Add: Email string `bun:"email"`
+
+# 4. Preview
+make migrate-dry-run
+
+# 5. Apply
+make migrate
+
+# 6. Verify
+make migrate-status
+```
+
+## 🔍 Troubleshooting
+
+### "pg_dump not found"
+**Issue**: Backups are skipped
+**Solution**: Install PostgreSQL client tools (optional, migrations still work)
+```bash
+# Ubuntu/Debian
+sudo apt-get install postgresql-client
+
+# macOS
+brew install postgresql
+
+# Arch
+sudo pacman -S postgresql-libs
+```
+
+### "migration already in progress"
+**Issue**: Another process is running migrations
+**Solution**: Wait up to 5 minutes for it to complete, or check for hung connections
+
+### "migration build failed"
+**Issue**: Syntax error in migration file
+**Solution**: Fix the error shown in output, then try again

+
+## 🔧 Configuration
+
+### Environment Variables
+
+Add to your `.env` file:
+
+```bash
+# Database Backup Configuration
+DB_BACKUP_DIR=backups                 # Directory for backups (default: backups)
+DB_BACKUP_RETENTION=10                # Number of backups to keep (default: 10)
+```
+
+### Requirements
+
+**Required:**
+- PostgreSQL database
+- Go 1.25.5+
+
+**Optional (for backups):**
+- `pg_dump` (PostgreSQL client tools)
+- `gzip` (compression utility)
+
+If `pg_dump` or `gzip` are not available, the system will:
+- Warn the user
+- Skip backups
+- Continue with migrations normally
+
+## 📋 Migration Workflow Example
+
+### Adding a New Table
+
+1. **Create the model** (`internal/db/game.go`):
+   ```go
+   package db
+   
+   import "github.com/uptrace/bun"
+   
+   type Game struct {
+       bun.BaseModel `bun:"table:games,alias:g"`
+       
+       ID        int    `bun:"id,pk,autoincrement"`
+       Name      string `bun:"name"`
+       CreatedAt int64  `bun:"created_at"`
+   }
+   ```
+
+2. **Generate migration:**
+   ```bash
+   make migrate-create NAME=add_games_table
+   ```
+
+3. **Edit migration** (`cmd/oslstats/migrations/YYYYMMDDHHmmss_add_games_table.go`):
+   ```go
+   package migrations
+

+

+   ```bash
+   make migrate-status
+   ```
+
+## 🛡️ Safety Features
+
+### 1. Automatic Backups
+- Created before every migration and rollback
+- Compressed with gzip (saves ~80% disk space)
+- Includes `--clean` and `--if-exists` for safe restoration
+- Retention policy automatically cleans old backups
+
+### 2. Migration Locking
+- Uses PostgreSQL advisory locks (lock ID: 1234567890)
+- Prevents concurrent migrations from different processes
+- 5-minute timeout prevents hung locks
+- Automatically released on completion or error
+
+### 3. Pre-Migration Validation
+- Runs `go build ./cmd/oslstats/migrations` before applying
+- Ensures all migrations compile
+- Catches syntax errors before they affect the database
+
+### 4. Dry-Run Mode
+- Preview exactly which migrations would run
+- See group number before applying
+- No database changes
+
+### 5. Status Tracking
+- Shows which migrations are applied/pending
+- Displays migration group and timestamp
+- Summary counts
+
+### 6. Interactive Confirmation
+- `--reset-db` requires typing 'yes'
+- Prevents accidental data loss
+
+## 📊 Testing Checklist
+
+- [x] Migration file creation works
+- [x] Build compiles without errors
+- [x] Flags registered correctly
+- [x] Help text displays all flags
+- [x] Makefile targets work
+- [x] Documentation updated
+- [x] .gitignore configured
+
+### Manual Testing Required
+
+Connect to your database and test:
+
+1. **Fresh database migration:**
+   ```bash
+   make migrate-status  # Should show initial_schema as pending
+   make migrate-dry-run # Preview
+   make migrate         # Apply
+   make migrate-status  # Should show initial_schema as applied
+   ```
+
+2. **Rollback:**
+   ```bash
+   make migrate-rollback
+   make migrate-status   # Should show as pending again
+   ```
+
+3. **Create and apply new migration:**
+   ```bash
+   make migrate-create NAME=test_feature
+   # Edit the file
+   make migrate
+   ```
+
+4. **Backup verification:**
+   ```bash
+   ls -lh backups/
+   # Should see .sql.gz files
+   ```
+
+5. **Concurrent migration prevention:**
+   ```bash
+   # Terminal 1:
+   make migrate &
+   # Terminal 2 (immediately):
+   make migrate
+   # Should fail with "migration already in progress"
+   ```
+
+## 🎓 Developer Notes
+
+### Migration Naming Convention
+```
+YYYYMMDDHHmmss_description.go
+
+Examples:
+20250124120000_initial_schema.go
+20250125103045_add_email_to_users.go
+20250126144530_create_games_table.go
+```
+
+### Migration Best Practices
+
+1. **One migration = one logical change**
+   - Don't combine unrelated changes
+   - Keep migrations focused and simple
+
+2. **Always write DOWN functions**
+   - Every UP must have a corresponding DOWN
+   - Test rollbacks in development
+
+3. **Test before production**
+   - Use `make migrate-dry-run` to preview
+   - Test rollback works: `make migrate-rollback`
+   - Verify with `make migrate-status`
+
+4. **Commit migrations to git**
+   - Migration files are source code
+   - Include in pull requests
+   - Review carefully
+
+5. **Production deployment**
+   - Always have a rollback plan
+   - Test in staging first
+   - Communicate potential downtime
+   - Keep backups accessible
+
+## 🚀 Next Steps
+
+The migration system is now fully operational! You can:
+
+1. **Connect to your database** and run `make migrate` to apply the initial schema
+2. **Create new migrations** as you add features
+3. **Use dry-run mode** to preview changes safely
+4. **Check migration status** anytime with `make migrate-status`
