+## Caching
+
+The SDK supports intelligent caching to reduce API calls and improve performance.
+
+### MemoryCache
+
+In-memory LRU cache with TTL (time-to-live) support.
+
+```python
+from wikijs import WikiJSClient
+from wikijs.cache import MemoryCache
+
+# Create cache with 5 minute TTL and max 1000 items
+cache = MemoryCache(ttl=300, max_size=1000)
+
+# Enable caching on client
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    cache=cache
+)
+
+# First call hits the API
+page = client.pages.get(123)
+
+# Second call returns from cache (instant)
+page = client.pages.get(123)
+
+# Get cache statistics
+stats = cache.get_stats()
+print(f"Hit rate: {stats['hit_rate']}")
+print(f"Cache size: {stats['current_size']}/{stats['max_size']}")
+```
+
+#### Parameters
+
+- **ttl** (`int`, optional): Time-to-live in seconds (default: 300 = 5 minutes)
+- **max_size** (`int`, optional): Maximum number of cached items (default: 1000)
+
+#### Methods
+
+##### get(key: CacheKey) → Optional[Any]
+
+Retrieve value from cache if not expired.
+
+##### set(key: CacheKey, value: Any) → None
+
+Store value in cache with TTL.
+
+##### delete(key: CacheKey) → None
+
+Remove specific value from cache.
+
+##### clear() → None
+
+Clear all cached values.
+
+##### invalidate_resource(resource_type: str, identifier: Optional[str] = None) → None
+
+Invalidate cache entries for a resource type.
+
+```python
+# Invalidate specific page
+cache.invalidate_resource('page', '123')
+
+# Invalidate all pages
+cache.invalidate_resource('page')
+```
+
+##### get_stats() → dict
+
+Get cache performance statistics.
+
+```python
+stats = cache.get_stats()
+# Returns: {
+#     'ttl': 300,
+#     'max_size': 1000,
+#     'current_size': 245,
+#     'hits': 1523,
+#     'misses': 278,
+#     'hit_rate': '84.54%',
+#     'total_requests': 1801
+# }
+```
+
+##### cleanup_expired() → int
+
+Manually remove expired entries. Returns number of entries removed.
+
+#### Cache Behavior
+
+- **GET operations** are cached (e.g., `pages.get()`, `users.get()`)
+- **Write operations** (create, update, delete) automatically invalidate cache
+- **LRU eviction**: Least recently used items removed when cache is full
+- **TTL expiration**: Entries automatically expire after TTL seconds

+# Async/Await Support
+
+The Wiki.js Python SDK provides full async/await support for high-performance concurrent operations using `aiohttp`.
+
+## Installation
+
+```bash
+pip install wikijs-python-sdk[async]
+```
+
+## Quick Start
+
+```python
+import asyncio
+from wikijs.aio import AsyncWikiJSClient
+
+async def main():
+    # Use async context manager for automatic cleanup
+    async with AsyncWikiJSClient(
+        base_url="https://wiki.example.com",
+        auth="your-api-key"
+    ) as client:
+        # All operations are now async
+        pages = await client.pages.list()
+        page = await client.pages.get(123)
+
+        print(f"Found {len(pages)} pages")
+        print(f"Page title: {page.title}")
+
+# Run the async function
+asyncio.run(main())
+```
+
+## Why Async?
+
+Async operations provide significant performance benefits for concurrent requests:
+
+- **Sequential (Sync)**: Requests happen one-by-one
+  - 100 requests @ 100ms each = 10 seconds
+
+- **Concurrent (Async)**: Requests happen simultaneously
+  - 100 requests @ 100ms each = ~100ms total
+  - **>3x faster** for typical workloads!
+
+## Basic Operations
+
+### Connection Testing
+
+```python
+async with AsyncWikiJSClient(url, auth) as client:
+    connected = await client.test_connection()
+    print(f"Connected: {connected}")
+```
+
+### Listing Pages
+
+```python
+# List all pages
+pages = await client.pages.list()
+
+# List with filtering
+pages = await client.pages.list(
+    limit=10,
+    offset=0,
+    search="documentation",
+    locale="en",
+    order_by="title",
+    order_direction="ASC"
+)
+```
+
+### Getting Pages
+
+```python
+# Get by ID
+page = await client.pages.get(123)
+
+# Get by path
+page = await client.pages.get_by_path("getting-started")
+```
+
+### Creating Pages
+
+```python
+from wikijs.models.page import PageCreate
+
+new_page = PageCreate(
+    title="New Page",
+    path="new-page",
+    content="# New Page\n\nContent here.",
+    description="A new page",
+    tags=["new", "example"]
+)
+
+created_page = await client.pages.create(new_page)
+print(f"Created page with ID: {created_page.id}")
+```
+
+### Updating Pages
+
+```python
+from wikijs.models.page import PageUpdate
+
+updates = PageUpdate(
+    title="Updated Title",
+    content="# Updated\n\nNew content.",
+    tags=["updated"]
+)
+
+updated_page = await client.pages.update(123, updates)
+```
+
+### Deleting Pages
+
+```python
+success = await client.pages.delete(123)
+print(f"Deleted: {success}")
+```
+
+### Searching Pages
+
+```python
+results = await client.pages.search("api documentation", limit=10)
+for page in results:
+    print(f"- {page.title}")
+```
+
+## Concurrent Operations
+
+The real power of async is running multiple operations concurrently:
+
+### Fetch Multiple Pages
+
+```python
+import asyncio
+
+# Sequential (slow)
+pages = []
+for page_id in [1, 2, 3, 4, 5]:
+    page = await client.pages.get(page_id)
+    pages.append(page)
+
+# Concurrent (fast!)
+tasks = [client.pages.get(page_id) for page_id in [1, 2, 3, 4, 5]]
+pages = await asyncio.gather(*tasks)
+```
+
+### Bulk Create Operations
+
+```python
+# Create multiple pages concurrently
+pages_to_create = [
+    PageCreate(title=f"Page {i}", path=f"page-{i}", content=f"Content {i}")
+    for i in range(1, 11)
+]
+
+tasks = [client.pages.create(page) for page in pages_to_create]
+created_pages = await asyncio.gather(*tasks, return_exceptions=True)
+
+# Filter out any errors
+successful = [p for p in created_pages if isinstance(p, Page)]
+print(f"Created {len(successful)} pages")
+```
+
+### Parallel Search Operations
+
+```python
+# Search multiple terms concurrently
+search_terms = ["api", "guide", "tutorial", "reference"]
+
+tasks = [client.pages.search(term) for term in search_terms]
+results = await asyncio.gather(*tasks)
+
+for term, pages in zip(search_terms, results):
+    print(f"{term}: {len(pages)} pages found")
+```
+
+## Error Handling
+
+Handle errors gracefully with try/except:
+
+```python
+from wikijs.exceptions import (
+    AuthenticationError,
+    NotFoundError,
+    APIError
+)
+
+async with AsyncWikiJSClient(url, auth) as client:
+    try:
+        page = await client.pages.get(999)
+    except NotFoundError:
+        print("Page not found")
+    except AuthenticationError:
+        print("Invalid API key")
+    except APIError as e:
+        print(f"API error: {e}")
+```
+
+### Handle Errors in Concurrent Operations
+
+```python
+# Use return_exceptions=True to continue on errors
+tasks = [client.pages.get(page_id) for page_id in [1, 2, 999, 4, 5]]
+results = await asyncio.gather(*tasks, return_exceptions=True)
+
+# Process results
+for i, result in enumerate(results):
+    if isinstance(result, Exception):
+        print(f"Page {i}: Error - {result}")
+    else:
+        print(f"Page {i}: {result.title}")
+```
+
+## Resource Management
+
+### Automatic Cleanup with Context Manager
+
+```python
+# Recommended: Use async context manager
+async with AsyncWikiJSClient(url, auth) as client:
+    # Session automatically closed when block exits
+    pages = await client.pages.list()
+```
+
+### Manual Resource Management
+
+```python
+# If you need manual control
+client = AsyncWikiJSClient(url, auth)
+try:
+    pages = await client.pages.list()
+finally:
+    await client.close()  # Important: close the session
+```
+
+## Advanced Configuration
+
+### Custom Connection Pool
+
+```python
+import aiohttp
+
+# Create custom connector for fine-tuned control
+connector = aiohttp.TCPConnector(
+    limit=200,              # Max connections
+    limit_per_host=50,      # Max per host
+    ttl_dns_cache=600,      # DNS cache TTL
+)
+
+async with AsyncWikiJSClient(
+    url,
+    auth,
+    connector=connector
+) as client:
+    # Use client with custom connector
+    pages = await client.pages.list()
+```
+
+### Custom Timeout
+
+```python
+# Set custom timeout (in seconds)
+async with AsyncWikiJSClient(
+    url,
+    auth,
+    timeout=60  # 60 second timeout
+) as client:
+    pages = await client.pages.list()
+```
+
+### Disable SSL Verification (Development Only)
+
+```python
+async with AsyncWikiJSClient(
+    url,
+    auth,
+    verify_ssl=False  # NOT recommended for production!
+) as client:
+    pages = await client.pages.list()
+```
+
+## Performance Best Practices
+
+### 1. Use Connection Pooling
+
+The async client automatically uses connection pooling. Keep a single client instance for your application:
+
+```python
+# Good: Reuse client
+client = AsyncWikiJSClient(url, auth)
+for i in range(100):
+    await client.pages.get(i)
+await client.close()
+
+# Bad: Create new client each time
+for i in range(100):
+    async with AsyncWikiJSClient(url, auth) as client:
+        await client.pages.get(i)  # New connection each time!
+```
+
+### 2. Batch Concurrent Operations
+
+Use `asyncio.gather()` for concurrent operations:
+
+```python
+# Fetch 100 pages concurrently (fast!)
+tasks = [client.pages.get(i) for i in range(1, 101)]
+pages = await asyncio.gather(*tasks, return_exceptions=True)
+```
+
+### 3. Use Semaphores to Control Concurrency
+
+Limit concurrent connections to avoid overwhelming the server:
+
+```python
+import asyncio
+
+async def fetch_page_with_semaphore(client, page_id, sem):
+    async with sem:  # Limit concurrent operations
+        return await client.pages.get(page_id)
+
+# Limit to 10 concurrent requests
+sem = asyncio.Semaphore(10)
+tasks = [
+    fetch_page_with_semaphore(client, i, sem)
+    for i in range(1, 101)
+]
+pages = await asyncio.gather(*tasks)
+```
+
+## Comparison: Sync vs Async
+
+| Feature | Sync Client | Async Client |
+|---------|-------------|--------------|
+| Import | `from wikijs import WikiJSClient` | `from wikijs.aio import AsyncWikiJSClient` |
+| Usage | `client.pages.get(123)` | `await client.pages.get(123)` |
+| Context Manager | `with WikiJSClient(...) as client:` | `async with AsyncWikiJSClient(...) as client:` |
+| Concurrency | Sequential only | Concurrent with `asyncio.gather()` |
+| Performance | Good for single requests | Excellent for multiple requests |
+| Dependencies | `requests` | `aiohttp` |
+| Best For | Simple scripts, sequential operations | Web apps, high-throughput, concurrent ops |
+
+## When to Use Async
+
+**Use Async When:**
+- Making multiple concurrent API calls
+- Building async web applications (FastAPI, aiohttp)
+- Need maximum throughput
+- Working with other async libraries
+
+**Use Sync When:**
+- Simple scripts or automation
+- Sequential operations only
+- Don't need concurrency
+- Simpler code is preferred
+
+## Complete Example
+
+```python
+import asyncio
+from wikijs.aio import AsyncWikiJSClient
+from wikijs.models.page import PageCreate, PageUpdate
+
+async def main():
+    async with AsyncWikiJSClient(
+        base_url="https://wiki.example.com",
+        auth="your-api-key"

+        print("Testing connection...")
+        connected = await client.test_connection()
+        print(f"Connected: {connected}")
+
+        # Create page
+        print("\nCreating page...")
+        new_page = PageCreate(
+            title="Test Page",

+        page = await client.pages.create(new_page)
+        print(f"Created page {page.id}: {page.title}")
+
+        # Update page
+        print("\nUpdating page...")
+        updates = PageUpdate(title="Updated Test Page")

+            client.pages.list(limit=5),
+            client.pages.search("test"),
+            client.pages.get_by_tags(["test"])
+        ]
+        list_results, search_results, tag_results = await asyncio.gather(*tasks)
+        print(f"Listed: {len(list_results)}")
+        print(f"Searched: {len(search_results)}")
+        print(f"By tags: {len(tag_results)}")
+
+        # Clean up
+        print("\nDeleting test page...")
+        await client.pages.delete(page.id)
+        print("Done!")
+
+if __name__ == "__main__":

+### Intelligent Caching
+
+The SDK supports intelligent caching to reduce API calls and improve performance.
+
+```python
+from wikijs import WikiJSClient
+from wikijs.cache import MemoryCache
+
+# Create cache with 5-minute TTL and max 1000 items
+cache = MemoryCache(ttl=300, max_size=1000)
+
+# Enable caching on client
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    cache=cache
+)
+
+# First call hits the API
+page = client.pages.get(123)  # ~200ms
+
+# Second call returns from cache (instant!)
+page = client.pages.get(123)  # <1ms
+
+# Check cache statistics
+stats = cache.get_stats()
+print(f"Cache hit rate: {stats['hit_rate']}")
+print(f"Total requests: {stats['total_requests']}")
+print(f"Cache size: {stats['current_size']}/{stats['max_size']}")
+```
+
+#### Cache Invalidation
+
+Caches are automatically invalidated on write operations:
+
+```python
+# Enable caching
+cache = MemoryCache(ttl=300)
+client = WikiJSClient("https://wiki.example.com", auth="key", cache=cache)
+
+# Get page (cached)
+page = client.pages.get(123)
+
+# Update page (cache automatically invalidated)
+client.pages.update(123, {"content": "New content"})
+
+# Next get() will fetch fresh data from API
+page = client.pages.get(123)  # Fresh data
+
+# Manual cache invalidation
+cache.invalidate_resource('page', '123')  # Invalidate specific page
+cache.invalidate_resource('page')  # Invalidate all pages
+cache.clear()  # Clear entire cache
+```
+

+
+## Overview
+
+The Users API provides complete user management capabilities for Wiki.js, including:
+
+- **CRUD Operations**: Create, read, update, and delete users
+- **User Search**: Find users by name or email
+- **User Listing**: List all users with filtering and pagination
+- **Group Management**: Assign users to groups
+- **Profile Management**: Update user profiles and settings
+
+Both **synchronous** and **asynchronous** clients are supported with identical interfaces.
+
+## User Models
+
+### User
+
+Represents a complete Wiki.js user with all profile information.
+
+```python
+from wikijs.models import User
+
+# User fields
+user = User(
+    id=1,
+    name="John Doe",
+    email="john@example.com",
+    provider_key="local",          # Authentication provider
+    is_system=False,               # System user flag
+    is_active=True,                # Account active status
+    is_verified=True,              # Email verified
+    location="New York",           # Optional location
+    job_title="Developer",         # Optional job title
+    timezone="America/New_York",   # Optional timezone
+    groups=[                       # User's groups
+        {"id": 1, "name": "Administrators"},
+        {"id": 2, "name": "Editors"}
+    ],
+    created_at="2024-01-01T00:00:00Z",
+    updated_at="2024-01-01T00:00:00Z",
+    last_login_at="2024-01-15T12:00:00Z"
+)
+```
+
+### UserCreate
+
+Model for creating new users.
+
+```python
+from wikijs.models import UserCreate
+
+# Minimal user creation
+new_user = UserCreate(
+    email="newuser@example.com",
+    name="New User",
+    password_raw="SecurePassword123"
+)
+
+# Complete user creation
+new_user = UserCreate(
+    email="newuser@example.com",
+    name="New User",
+    password_raw="SecurePassword123",
+    provider_key="local",          # Default: "local"
+    groups=[1, 2],                 # Group IDs
+    must_change_password=False,    # Force password change on first login
+    send_welcome_email=True,       # Send welcome email
+    location="San Francisco",
+    job_title="Software Engineer",
+    timezone="America/Los_Angeles"
+)
+```
+
+**Validation Rules:**
+- Email must be valid format
+- Name must be 2-255 characters
+- Password must be 6-255 characters
+- Groups must be list of integer IDs
+
+### UserUpdate
+
+Model for updating existing users. All fields are optional.
+
+```python
+from wikijs.models import UserUpdate
+
+# Partial update - only specified fields are changed
+update_data = UserUpdate(
+    name="Jane Doe",
+    location="Los Angeles"
+)
+
+# Complete update
+update_data = UserUpdate(
+    name="Jane Doe",
+    email="jane@example.com",
+    password_raw="NewPassword123",
+    location="Los Angeles",
+    job_title="Senior Developer",
+    timezone="America/Los_Angeles",
+    groups=[1, 2, 3],              # Replace all groups
+    is_active=True,
+    is_verified=True
+)
+```
+
+**Notes:**
+- Only non-None fields are sent to the API
+- Partial updates are fully supported
+- Password is optional (only include if changing)
+
+### UserGroup
+
+Represents a user's group membership.
+
+```python
+from wikijs.models import UserGroup
+
+group = UserGroup(
+    id=1,
+    name="Administrators"
+)
+```
+
+## Basic Operations
+
+### Synchronous Client
+
+```python
+from wikijs import WikiJSClient
+from wikijs.models import UserCreate, UserUpdate
+
+# Initialize client
+client = WikiJSClient(
+    base_url="https://wiki.example.com",
+    auth="your-api-key"
+)
+
+# List all users
+users = client.users.list()
+for user in users:
+    print(f"{user.name} ({user.email})")
+
+# List with filtering
+users = client.users.list(
+    limit=10,
+    offset=0,
+    search="john",
+    order_by="name",
+    order_direction="ASC"
+)
+
+# Get a specific user
+user = client.users.get(user_id=1)
+print(f"User: {user.name}")
+print(f"Email: {user.email}")
+print(f"Groups: {[g.name for g in user.groups]}")
+
+# Create a new user
+new_user_data = UserCreate(
+    email="newuser@example.com",
+    name="New User",
+    password_raw="SecurePassword123",
+    groups=[1, 2]
+)
+created_user = client.users.create(new_user_data)
+print(f"Created user: {created_user.id}")
+
+# Update a user
+update_data = UserUpdate(
+    name="Updated Name",
+    location="New Location"
+)
+updated_user = client.users.update(
+    user_id=created_user.id,
+    user_data=update_data
+)
+
+# Search for users
+results = client.users.search("john", limit=5)
+for user in results:
+    print(f"Found: {user.name} ({user.email})")
+
+# Delete a user
+success = client.users.delete(user_id=created_user.id)
+if success:
+    print("User deleted successfully")
+```
+
+## Async Operations
+
+### Async Client
+
+```python
+import asyncio
+from wikijs.aio import AsyncWikiJSClient
+from wikijs.models import UserCreate, UserUpdate
+
+async def manage_users():
+    # Initialize async client
+    async with AsyncWikiJSClient(
+        base_url="https://wiki.example.com",
+        auth="your-api-key"
+    ) as client:
+        # List users
+        users = await client.users.list()
+
+        # Get specific user
+        user = await client.users.get(user_id=1)
+
+        # Create user
+        new_user_data = UserCreate(
+            email="newuser@example.com",
+            name="New User",
+            password_raw="SecurePassword123"
+        )
+        created_user = await client.users.create(new_user_data)
+
+        # Update user
+        update_data = UserUpdate(name="Updated Name")
+        updated_user = await client.users.update(
+            user_id=created_user.id,
+            user_data=update_data
+        )
+
+        # Search users
+        results = await client.users.search("john", limit=5)
+
+        # Delete user
+        success = await client.users.delete(user_id=created_user.id)
+
+# Run async function
+asyncio.run(manage_users())
+```
+
+### Concurrent Operations
+
+Process multiple users concurrently for better performance:
+
+```python
+import asyncio
+from wikijs.aio import AsyncWikiJSClient
+from wikijs.models import UserUpdate
+
+async def update_users_concurrently():
+    async with AsyncWikiJSClient(
+        base_url="https://wiki.example.com",
+        auth="your-api-key"
+    ) as client:
+        # Get all users
+        users = await client.users.list()
+
+        # Update all users concurrently
+        update_data = UserUpdate(is_verified=True)
+
+        tasks = [
+            client.users.update(user.id, update_data)
+            for user in users
+            if not user.is_verified
+        ]
+
+        # Execute all updates concurrently
+        results = await asyncio.gather(*tasks, return_exceptions=True)
+
+        # Process results
+        success_count = sum(1 for r in results if not isinstance(r, Exception))
+        print(f"Updated {success_count}/{len(tasks)} users")
+
+asyncio.run(update_users_concurrently())
+```
+
+## Advanced Usage
+
+### Using Dictionaries Instead of Models
+
+You can use dictionaries instead of model objects:
+
+```python
+# Create user from dict
+user_dict = {
+    "email": "user@example.com",
+    "name": "Test User",
+    "password_raw": "SecurePassword123",
+    "groups": [1, 2]
+}
+created_user = client.users.create(user_dict)
+
+# Update user from dict
+update_dict = {
+    "name": "Updated Name",
+    "location": "New Location"
+}
+updated_user = client.users.update(user_id=1, user_data=update_dict)
+```
+
+### Pagination
+
+Handle large user lists with pagination:
+
+```python
+# Fetch users in batches
+def fetch_all_users(client, batch_size=50):
+    all_users = []
+    offset = 0
+
+    while True:
+        batch = client.users.list(
+            limit=batch_size,
+            offset=offset,
+            order_by="id",
+            order_direction="ASC"
+        )
+
+        if not batch:
+            break
+
+        all_users.extend(batch)
+        offset += batch_size
+
+        print(f"Fetched {len(all_users)} users so far...")
+
+    return all_users
+
+# Async pagination
+async def fetch_all_users_async(client, batch_size=50):
+    all_users = []
+    offset = 0
+
+    while True:
+        batch = await client.users.list(
+            limit=batch_size,
+            offset=offset,
+            order_by="id",
+            order_direction="ASC"
+        )
+
+        if not batch:
+            break
+
+        all_users.extend(batch)
+        offset += batch_size
+
+    return all_users
+```
+
+### Group Management
+
+Manage user group assignments:
+
+```python
+from wikijs.models import UserUpdate
+
+# Add user to groups
+update_data = UserUpdate(groups=[1, 2, 3])  # Group IDs
+updated_user = client.users.update(user_id=1, user_data=update_data)
+
+# Remove user from all groups
+update_data = UserUpdate(groups=[])
+updated_user = client.users.update(user_id=1, user_data=update_data)
+
+# Get user's current groups
+user = client.users.get(user_id=1)
+print("User groups:")
+for group in user.groups:
+    print(f"  - {group.name} (ID: {group.id})")
+```
+
+### Bulk User Creation
+
+Create multiple users efficiently:
+
+```python
+from wikijs.models import UserCreate
+
+# Sync bulk creation
+def create_users_bulk(client, user_data_list):
+    created_users = []
+
+    for user_data in user_data_list:
+        try:
+            user = client.users.create(user_data)
+            created_users.append(user)
+            print(f"Created: {user.name}")
+        except Exception as e:
+            print(f"Failed to create {user_data['name']}: {e}")
+
+    return created_users
+
+# Async bulk creation (concurrent)
+async def create_users_bulk_async(client, user_data_list):
+    tasks = [
+        client.users.create(user_data)
+        for user_data in user_data_list
+    ]
+
+    results = await asyncio.gather(*tasks, return_exceptions=True)
+
+    created_users = [
+        r for r in results if not isinstance(r, Exception)
+    ]
+
+    print(f"Created {len(created_users)}/{len(user_data_list)} users")
+    return created_users
+```
+
+## Error Handling
+
+### Common Exceptions
+
+```python
+from wikijs.exceptions import (
+    ValidationError,
+    APIError,
+    AuthenticationError,
+    ConnectionError,
+    TimeoutError
+)
+
+try:
+    # Create user with invalid data
+    user_data = UserCreate(
+        email="invalid-email",  # Invalid format
+        name="Test",
+        password_raw="123"      # Too short
+    )
+except ValidationError as e:
+    print(f"Validation error: {e}")
+
+try:
+    # Get non-existent user
+    user = client.users.get(user_id=99999)
+except APIError as e:
+    print(f"API error: {e}")
+
+try:
+    # Invalid authentication
+    client = WikiJSClient(
+        base_url="https://wiki.example.com",
+        auth="invalid-key"
+    )
+    users = client.users.list()
+except AuthenticationError as e:
+    print(f"Authentication failed: {e}")
+```
+
+### Robust Error Handling
+
+```python
+from wikijs.exceptions import ValidationError, APIError
+
+def create_user_safely(client, user_data):
+    """Create user with comprehensive error handling."""
+    try:
+        # Validate data first
+        validated_data = UserCreate(**user_data)
+
+        # Create user
+        user = client.users.create(validated_data)
+        print(f"✓ Created user: {user.name} (ID: {user.id})")
+        return user
+
+    except ValidationError as e:
+        print(f"✗ Validation error: {e}")
+        # Handle validation errors (e.g., fix data and retry)
+        return None
+
+    except APIError as e:
+        if "already exists" in str(e).lower():
+            print(f"✗ User already exists: {user_data['email']}")
+            # Handle duplicate user
+            return None
+        else:
+            print(f"✗ API error: {e}")
+            raise
+
+    except Exception as e:
+        print(f"✗ Unexpected error: {e}")
+        raise
+
+# Async version
+async def create_user_safely_async(client, user_data):
+    try:
+        validated_data = UserCreate(**user_data)
+        user = await client.users.create(validated_data)
+        print(f"✓ Created user: {user.name} (ID: {user.id})")
+        return user
+    except ValidationError as e:
+        print(f"✗ Validation error: {e}")
+        return None
+    except APIError as e:
+        if "already exists" in str(e).lower():
+            print(f"✗ User already exists: {user_data['email']}")
+            return None
+        else:
+            print(f"✗ API error: {e}")
+            raise
+```
+
+## Best Practices
+
+### 1. Use Models for Type Safety
+
+Always use Pydantic models for better validation and IDE support:
+
+```python
+# Good - type safe with validation
+user_data = UserCreate(
+    email="user@example.com",
+    name="Test User",
+    password_raw="SecurePassword123"
+)
+user = client.users.create(user_data)
+
+# Acceptable - but less type safe
+user_dict = {
+    "email": "user@example.com",
+    "name": "Test User",
+    "password_raw": "SecurePassword123"
+}
+user = client.users.create(user_dict)
+```
+
+### 2. Handle Pagination for Large Datasets
+
+Always paginate when dealing with many users:
+
+```python
+# Good - paginated
+all_users = []
+offset = 0
+batch_size = 50
+
+while True:
+    batch = client.users.list(limit=batch_size, offset=offset)
+    if not batch:
+        break
+    all_users.extend(batch)
+    offset += batch_size
+
+# Bad - loads all users at once
+all_users = client.users.list()  # May be slow for large user bases
+```
+
+### 3. Use Async for Concurrent Operations
+
+Use async client for better performance when processing multiple users:
+
+```python
+# Good - concurrent async operations
+async with AsyncWikiJSClient(...) as client:
+    tasks = [client.users.get(id) for id in user_ids]
+    users = await asyncio.gather(*tasks)
+
+# Less efficient - sequential sync operations
+for user_id in user_ids:
+    user = client.users.get(user_id)
+```
+
+### 4. Validate Before API Calls
+
+Catch validation errors early:
+
+```python
+# Good - validate first
+try:
+    user_data = UserCreate(**raw_data)
+    user = client.users.create(user_data)
+except ValidationError as e:
+    print(f"Invalid data: {e}")
+    # Fix data before API call
+
+# Less efficient - validation happens during API call
+user = client.users.create(raw_data)
+```
+
+### 5. Use Partial Updates
+
+Only update fields that changed:
+
+```python
+# Good - only update changed fields
+update_data = UserUpdate(name="New Name")
+user = client.users.update(user_id=1, user_data=update_data)
+
+# Wasteful - updates all fields
+update_data = UserUpdate(
+    name="New Name",
+    email=user.email,
+    location=user.location,
+    # ... all other fields
+)
+user = client.users.update(user_id=1, user_data=update_data)
+```
+
+### 6. Implement Retry Logic for Production
+
+```python
+import time
+from wikijs.exceptions import ConnectionError, TimeoutError
+
+def create_user_with_retry(client, user_data, max_retries=3):
+    """Create user with automatic retry on transient failures."""
+    for attempt in range(max_retries):
+        try:
+            return client.users.create(user_data)
+        except (ConnectionError, TimeoutError) as e:
+            if attempt < max_retries - 1:
+                wait_time = 2 ** attempt  # Exponential backoff
+                print(f"Retry {attempt + 1}/{max_retries} after {wait_time}s...")
+                time.sleep(wait_time)
+            else:
+                raise
+```
+
+### 7. Secure Password Handling
+
+```python
+import getpass
+from wikijs.models import UserCreate
+
+# Good - prompt for password securely
+password = getpass.getpass("Enter password: ")
+user_data = UserCreate(
+    email="user@example.com",
+    name="Test User",
+    password_raw=password
+)
+
+# Bad - hardcoded passwords
+user_data = UserCreate(
+    email="user@example.com",
+    name="Test User",
+    password_raw="password123"  # Never do this!
+)
+```
