+## Version 1.2.0 - Package Ecosystem & Enhanced Templates 🔥
 
-**Theme:** Transforming Weevil from project generator to ecosystem platform. Teams can extend projects with community-shared components.
+**Theme:** Transforming Weevil from project generator to ecosystem platform. Teams can extend projects with community-shared components and additional professional templates.
 
 **Status:** Planning - Expected Q2 2026
 
+### Template Metadata & Improved Display ⚠️
+
+**Feature:** Template discovery with rich metadata and formatted display
+
+**Description:** Enhance template system with metadata files for better discoverability:
+
+**Template Metadata (`template.toml`):**
+```toml
+[template]
+name = "localization"
+description = "Grid-based robot localization with sensor fusion"
+file_count = 21
+test_count = 3
+perfect_for = "Advanced autonomous navigation"
+
+[includes]
+items = [
+    "12x12 field grid system",
+    "Multi-sensor fusion (encoders + IMU + vision)",
+    "Fault-tolerant positioning"
+]
+```
+
+**Improved `--list-templates` Output:**
+```
+Available templates:
+
+  basic (default)
+    Minimal FTC project structure
+    Files: ~10 | Tests: 1
+    Perfect for: Teams starting from scratch
+
+  testing
+    Professional testing showcase with examples
+    Files: ~30 | Tests: 45
+    Perfect for: Learning best practices
+    Includes:
+      • 3 complete subsystems
+      • Hardware abstraction layer
+      • 45 passing tests
+
+  localization
+    Grid-based robot localization with sensor fusion
+    Files: ~21 | Tests: 3
+    Perfect for: Advanced autonomous navigation
+    Includes:
+      • 12x12 field grid system
+      • Multi-sensor fusion
+      • Fault-tolerant positioning
+
+Usage:
+  weevil new <project-name>                    # Uses basic
+  weevil new <project-name> --template testing # Uses testing
+```
+
+**Status:** ⚠️ Planned for v1.2.0
+
+**Priority:** MEDIUM-HIGH - Improves template discoverability
+
+**Effort:** 1-2 days (metadata format + CLI formatting)

+
+### Localization Template ⚠️
+
+**Feature:** Grid-based localization template for advanced autonomous
+
+**Description:** Professional robot localization system with sensor fusion and fault tolerance:
+
+**What's Included:**
+- **Grid System** - 12ft x 12ft field divided into 12x12 grid (12" cells)
+- **Sensor Fusion** - Combine odometry (encoders), IMU (gyro), and vision (AprilTags)
+- **Fault Tolerance** - Graceful degradation when sensors fail
+- **Lookup Tables** - Pre-computed navigation strategies
+- **21 Files** - 7 localization classes, 3 hardware interfaces, 3 mocks, 3 tests, 2 docs
+- **3 Comprehensive Tests** - Grid math, sensor fusion, fault tolerance
+
+**Core Components:**
+- `GridCell.java` - Cell in 12x12 grid (0-11, 0-11)
+- `Pose2D.java` - Position (x, y) + heading with angle normalization
+- `FieldGrid.java` - Field coordinate system and conversions
+- `RobotLocalizer.java` - Multi-sensor fusion engine
+- `OdometryTracker.java` - Dead reckoning from wheel encoders
+- `ImuLocalizer.java` - Heading tracking from gyroscope
+- `VisionLocalizer.java` - Position from AprilTags
+
+**Sensor Fusion Priority:**
+1. Vision (AprilTags) → ±2" accuracy, 100% confidence
+2. IMU + Odometry → ±4" accuracy, 70% confidence
+3. Odometry only → ±12" accuracy, 40% confidence
+
+**Rationale:** Teaches professional robotics concepts (Kalman-filter-style sensor fusion, fault tolerance, grid-based navigation). No other FTC tool has this. Positions Nexus Workshops as teaching advanced autonomous programming.
+
+**Usage:**
+```bash
+weevil new my-robot --template localization
+cd my-robot
+./gradlew test  # 3 tests pass
+# Modify for your robot's sensors and autonomous strategy
+```
+
+**Status:** ⚠️ Template complete, ready to integrate in v1.2.0
+
+**Priority:** HIGH - Unique differentiator, advanced autonomous capability
+
+**Effort:** Template already created, integration 1 day

 ### `weevil add` - Component Package Manager ⚠️ **THE NEXT BIG THING**
 
 **Feature:** Package manager for sharing and reusing FTC robot code components
