 ### JWT Authentication
 
+JWT authentication uses token-based authentication with automatic refresh capabilities.
+
 ```python
 from wikijs.auth import JWTAuth
 
+# Initialize with JWT token and refresh token
 auth = JWTAuth(
-    username="your-username",
-    password="your-password"
+    token="eyJ0eXAiOiJKV1QiLCJhbGc...",
+    base_url="https://wiki.example.com",
+    refresh_token="refresh_token_here",  # Optional: for automatic token refresh
+    expires_at=1234567890  # Optional: Unix timestamp of token expiration
 )
 client = WikiJSClient("https://wiki.example.com", auth=auth)
 ```
 
+**Parameters:**
+- **token** (`str`): The JWT token string
+- **base_url** (`str`): Wiki.js instance URL (needed for token refresh)
+- **refresh_token** (`str`, optional): Refresh token for automatic renewal
+- **expires_at** (`float`, optional): Token expiration timestamp (Unix timestamp)
+
+**Features:**
+- Automatic token expiration detection
+- Automatic token refresh when refresh token is provided
+- Configurable refresh buffer (default: 5 minutes before expiration)
+- Token masking in logs for security

+
+## 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
