💻 Code Examples

Each topic includes practical, well-commented code examples that demonstrate key concepts. Our examples:

• Follow best practices for production-ready code
• Include comprehensive error handling
• Provide clear comments explaining each step
• Are tested in real-world scenarios
• Include both basic and advanced implementations

Example from our Client-Server Architecture section:

// Message header structure
struct message_header {
    uint8_t  version;       // Protocol version
    uint8_t  type;          // Message type
    uint16_t command;       // Command identifier
    uint32_t payload_size;  // Size of the payload
    uint32_t sequence_id;   // Message sequence number
};

// Complete message structure
struct message {
    struct message_header header;
    char payload[MAX_PAYLOAD_SIZE];
};

📝 Content Creation

Adding New Documentation

We use a custom script to easily add content from sources like GeeksforGeeks:

bun run add-doc <url>

This automatically:

• Scrapes content from the provided URL
• Downloads images to the public folder
• Generates well-formatted MDX files
• Applies proper formatting and styling

Manual Content Creation

1. Create a new MDX file in the appropriate directory under content/docs/
2. Add frontmatter with title and description
3. Write your content using Markdown and MDX components
4. Add code examples, images, and other resources as needed

🤝 Contributing
