+# Capabilities Discovery Feature - Demonstration
+
+## Overview
+This document demonstrates the new capabilities discovery feature added to EasyGraph in response to the question "你能做什么？" (What can you do?).
+
+## Feature Description
+The capabilities module provides two main functions to help users discover what EasyGraph can do:
+
+1. **`show_capabilities()`** - Displays a comprehensive, formatted overview
+2. **`get_capabilities_dict()`** - Returns capabilities as a structured dictionary
+3. **`能做什么()`** - Chinese language alias for `show_capabilities()`
+
+## Usage Examples
+
+### Example 1: Display All Capabilities
+```python
+import easygraph as eg
+eg.show_capabilities()
+```
+
+### Example 2: Get Capabilities Programmatically
+```python
+import easygraph as eg
+caps = eg.get_capabilities_dict()
+
+# View available categories
+print(caps.keys())
+# Output: dict_keys(['graph_types', 'centrality', 'community_detection', 
+#                    'structural_holes', 'components', 'basic_metrics', 
+#                    'path_algorithms', 'core_decomposition', 'graph_embedding', 
+#                    'graph_generation', 'hypergraph', 'gpu_acceleration', 
+#                    'visualization', 'io_formats'])
+
+# View specific capabilities
+print(caps['centrality'])
+# Output: ['degree_centrality', 'betweenness_centrality', 'closeness_centrality', 
+#          'pagerank', 'katz_centrality', 'ego_betweenness', 
+#          'flow_betweenness', 'laplacian_centrality']
+```
+
+### Example 3: Chinese Language Support
+```python
+import easygraph as eg
+eg.能做什么()  # Same as show_capabilities()
+```
+
+## Sample Output
+When you call `eg.show_capabilities()`, you'll see:
+
+```
