+### Core Resources
 | Resource | Description |
 |----------|-------------|
 | `nc://capabilities` | Access Nextcloud server capabilities |
 | `notes://settings` | Access Notes app settings |
 | `nc://Notes/{note_id}/attachments/{attachment_filename}` | Access attachments for notes |

+### Tools vs Resources
+
+**Tools** are for actions and operations:
+- Create, update, delete operations
+- Structured responses with validation
+- Error handling and business logic
+- Examples: `deck_create_card`, `deck_update_stack`
+
+**Resources** are for data browsing and discovery:
+- Read-only access to existing data
+- Automatic listing by MCP clients
+- Raw data format for exploration

+### Deck Project Management
+
+The server provides complete Nextcloud Deck integration, enabling you to manage projects, tasks, and workflows:
+
+- Create and manage boards, stacks, and cards
+- Organize tasks with labels and user assignments
+- Archive/unarchive cards and reorder within or between stacks
+- Full CRUD operations on all Deck entities
+- Browse project structure through hierarchical resources
+
+**Usage Examples:**
