+# ✅ Stairway Creator - Final Correct Implementation
+
+## Understanding the Requirement
+
+You wanted a tool that helps **draw individual step lines quickly** within the current editor workflow:
+
+> "if I set a start and end points, stairs get generated in between as straight lines (like in the example). Then, the number of stairs on this staircase should be configurable and the changes should be seen immediately"
+
+## ✅ Correct Implementation
+
+### **What It Does**
+- **Click 2 Points**: Define start and end of stairway path
+- **Generate Step Lines**: Creates individual straight lines perpendicular to the path
+- **Real-time Preview**: See changes immediately as you adjust step count/width
+- **Individual Editing**: Each step line can be edited separately after generation
+- **Integrated Workflow**: Works within the current geometry editing system
+
+### **User Workflow**
+1. **Start Geometry Creation**: Begin creating any geometry type
+2. **Activate Stairway Creator**: Click 🏗️ button
+3. **Place Points**: Click start point, then end point
+4. **Configure**: Adjust number of steps (3-50) and step width (0.1-2.0m)
+5. **Real-time Preview**: See step positions update immediately
+6. **Generate**: Click "Generate Stairs" to create individual step lines
+7. **Edit**: Each step line becomes individually editable
+
+### **Technical Implementation**
+
+**Frontend Only** (`editor.js`):
+- **Point Collection**: Click-based point placement system
+- **Real-time Calculation**: Live preview updates as parameters change
+- **Step Generation**: Creates individual Leaflet polylines
+- **Geometry Integration**: Updates form with MultiLineString geometry
+- **Individual Editing**: Each step line is separately editable
+
+**Key Functions**:
+```javascript
+_calculate_straight_stairs(start, end) {
+    // Calculate perpendicular step positions
+    // Between start and end points
+    // With configurable count and width
+}
+
+_draw_step_lines(steps) {
+    // Create individual editable polylines
+    // Group them for collective editing
+    // Update geometry form
+}
+```
+
+### **Visual Preview System**
+- **Point Markers**: Red numbered circles show clicked points
+- **Step Preview**: Green lines show where steps will be placed
+- **Real-time Updates**: Preview updates as you change:
+  - Number of steps (slider/input)
+  - Step width (affects line length)
+  - Immediate visual feedback
+
+### **Geometry Output**
+- **MultiLineString**: Single geometry containing all step lines
+- **Individual Components**: Each step is a separate line within the MultiLineString
+- **Editable**: Each step line can be modified individually after creation
+- **Properly Formatted**: Compatible with c3nav's geometry system
+
+## 🎯 **Benefits**
+
+✅ **Speed**: Generate 10+ step lines in seconds vs minutes of manual drawing
+✅ **Precision**: Perfect perpendicular alignment and equal spacing
+✅ **Flexibility**: Configurable step count and width
+✅ **Real-time**: Immediate visual feedback as you adjust parameters
+✅ **Integration**: Works within existing editor workflow
+✅ **Editability**: Each generated step remains individually editable
+
+## 🧪 **Testing Process**
+
+1. **Start geometry creation** (any type)
+2. **Click 🏗️ button** to activate stairway creator
+3. **Click start point** on the map
+4. **Click end point** to define the stairway path
+5. **Adjust step count** (see preview update in real-time)
+6. **Adjust step width** (see line lengths change)
+7. **Click "Generate Stairs"** to create the step lines
+8. **Verify individual editing** - each step line should be separately editable
+
+## 🎉 **Result**
+
+This implementation provides exactly what you requested:
+- **Quick step generation** between two points
+- **Individual step lines** that can be edited separately
+- **Real-time configuration** with immediate visual feedback
+- **Straight line steps** perpendicular to the defined path
+- **Integrated workflow** within the existing editor
+
+The tool transforms the tedious process of manually drawing each step line into a quick, configurable, visual workflow that generates properly aligned individual step geometries!
