+# Task Structure Improvement
+
+This document describes the improvements made to the milestone task structure in the Boundless platform.
+
+## Overview
+
+Previously, milestones only had a simple `deliverables: string[]` field which was too simplistic for proper project management. This update adds a comprehensive task tracking system to milestones.
+
+## New Task Type
+
+```typescript
+export interface Task {
+  id: string;
+  title: string;
+  description?: string;
+  status: 'todo' | 'in_progress' | 'completed';
+  priority?: 'low' | 'medium' | 'high';
+  assignee?: string;
+  dueDate?: string;
+  completedAt?: string;
+  order: number;
+}
+```
+
+## Updated Milestone Interface
+
+The Milestone interface now includes:
+- `tasks?: Task[]` - New structured task list with full metadata
+- `deliverables: string[]` - Legacy field kept for backward compatibility
+
+## UI Components
+
+### TaskList Component
+
+A new `TaskList` component displays tasks with:
+- Progress bar showing completion percentage
+- Task status indicators (todo, in progress, completed)
+- Priority badges (low, medium, high)
+- Assignee information
+- Due dates and completion dates
+
+### Milestone Card Enhancements
+
+Milestone cards now show:
+- Task progress bar when tasks are present
+- "X/Y tasks" completion count
+- Visual progress indicator
+
+## Example Usage
+
+### Backend API Response
+
+```json
+{
+  "milestones": [
+    {
+      "id": "milestone-1",
+      "name": "Initial Development",
+      "description": "Set up the basic infrastructure",
+      "status": "in-progress",
+      "amount": 10000,
+      "startDate": "2024-01-01",
+      "endDate": "2024-02-01",
+      "tasks": [
+        {
+          "id": "task-1",
+          "title": "Set up repository",
+          "description": "Create GitHub repo and initial structure",
+          "status": "completed",
+          "priority": "high",
+          "assignee": "john@example.com",
+          "dueDate": "2024-01-05",
+          "completedAt": "2024-01-04",
+          "order": 1
+        },
+        {
+          "id": "task-2",
+          "title": "Configure CI/CD pipeline",
+          "status": "in_progress",
+          "priority": "high",
+          "assignee": "jane@example.com",
+          "dueDate": "2024-01-10",
+          "order": 2
+        },
+        {
+          "id": "task-3",
+          "title": "Write documentation",
+          "status": "todo",
+          "priority": "medium",
+          "dueDate": "2024-01-15",
+          "order": 3
+        }
+      ]
+    }
+  ]
+}
+```
+
+## Backward Compatibility
+
+The system maintains backward compatibility with existing milestones that use the `deliverables` field:
+
+- If a milestone has `tasks`, they will be displayed with full functionality
+- If a milestone only has `deliverables`, they will be displayed as simple task items
+- Both fields can coexist during the migration period
+
+## Benefits
+
+1. **Better Project Tracking**: Track individual tasks with status, priority, and assignment
+2. **Visual Progress**: See at-a-glance task completion in milestone cards
+3. **Accountability**: Assign tasks to specific team members
+4. **Prioritization**: Mark tasks with priority levels for better planning
+5. **Timeline Management**: Set and track due dates for individual tasks
+6. **Historical Data**: Track when tasks were completed
+
+## Migration Path
+
+For existing milestones with deliverables:
+
+```typescript
+// Old format
+{
+  deliverables: [
+    "Complete user authentication",
+    "Build dashboard UI",
+    "Deploy to production"
+  ]
+}
+
+// Can be migrated to new format
+{
+  tasks: [
+    {
+      id: "1",
+      title: "Complete user authentication",
+      status: "completed",
+      order: 1
+    },
+    {
+      id: "2", 
+      title: "Build dashboard UI",
+      status: "in_progress",
+      order: 2
+    },
+    {
+      id: "3",
+      title: "Deploy to production",
+      status: "todo",
+      order: 3
+    }
+  ]
+}
+```
