+```python
+# Current sync client (unchanged)
+from wikijs import WikiJSClient
+
+# New async client
+from wikijs.aio import AsyncWikiJSClient

+
+### 3.1 Intelligent Caching Layer
+
+#### 3.1.1 Cache Architecture
+**Objective**: Pluggable caching with multiple backends
+
+**Design**:
+```python
+from wikijs import WikiJSClient
+from wikijs.cache import MemoryCache, RedisCache, FileCache
+
+# No caching (default - backward compatible)
+client = WikiJSClient(url, auth)
+
+# Memory cache (development)
+client = WikiJSClient(url, auth, cache=MemoryCache(ttl=300, max_size=1000))
+
+# Redis cache (production)
+client = WikiJSClient(url, auth, cache=RedisCache(
+    host="localhost",
+    ttl=600,
+    key_prefix="wikijs:"
+))
+
+# File cache (persistent)
+client = WikiJSClient(url, auth, cache=FileCache(
+    cache_dir="/tmp/wikijs_cache",
+    ttl=3600
+))
+```
+
+**File Structure**:
+```
+wikijs/cache/
+├── __init__.py           # Cache exports
+├── base.py              # CacheBackend abstract base class
+├── memory.py            # MemoryCache implementation

+
+tests/cache/
+├── test_memory_cache.py
+├── test_redis_cache.py
+├── test_file_cache.py
+└── test_invalidation.py
+```
+
+**Tasks**:
+1. ✅ **Create cache base classes** (`wikijs/cache/base.py`)
+   ```python
+   from abc import ABC, abstractmethod
+   from typing import Any, Optional
+
+   class CacheBackend(ABC):
+       @abstractmethod
+       def get(self, key: str) -> Optional[Any]:
+           """Get value from cache."""
+
+       @abstractmethod
+       def set(self, key: str, value: Any, ttl: Optional[int] = None) -> None:
+           """Set value in cache."""
+
+       @abstractmethod
+       def delete(self, key: str) -> None:
+           """Delete key from cache."""
+
+       @abstractmethod
+       def clear(self) -> None:
+           """Clear all cache entries."""
+   ```
+
+2. ✅ **Implement MemoryCache** (LRU with TTL)
+   - Use `collections.OrderedDict` for LRU
+   - Timestamp-based TTL expiration
+   - Thread-safe operations with `threading.Lock`
+   - Configurable max size (default: 1000 entries)
+
+3. ✅ **Implement RedisCache**
+   - Use `redis-py` library
+   - Automatic serialization with `pickle`
+   - Connection pooling
+   - Optional key prefix for multi-tenant support
+
+4. ✅ **Implement FileCache**
+   - Store as JSON/pickle files
+   - Directory-based organization
+   - Automatic cleanup of expired entries
+   - Disk space management
+
+5. ✅ **Integrate caching into client**
+   - Cache key generation (URL + params hash)
+   - Cache middleware in `_request()` method
+   - Only cache GET requests (not POST/PUT/DELETE)
+   - Respect Cache-Control headers if present
+
+**Cache Invalidation Strategy**:
+```python
+# Time-based (TTL)
+cache = MemoryCache(ttl=300)  # 5 minutes
+
+# Event-based invalidation
+client.pages.update(page_id, content="New")  # Auto-invalidate cached page
+
+# Manual invalidation

+   - `delete_many(ids: List[int]) -> List[bool]`
+
+3. ✅ **Error handling for partial failures**

+## 📝 Testing Strategy
+
+### Test Pyramid
+
+```
+        E2E Tests (5%)
+       /              \
+      Integration (15%)
+     /                  \
+    Unit Tests (80%)
+```
+
+### Testing Requirements by Phase
+
+**Phase 2**:
+- Unit: >95% coverage
+- Integration: All CRUD operations
+- Performance: Async vs sync benchmarks
+- Security: Auth validation
+
+**Phase 3**:
+- Load: 10,000+ requests
+- Chaos: Random failure injection
+- Stability: 24+ hour runs
+- Cache: Hit rate >80%
+
+**Phase 4**:
+- End-to-End: Complete workflows
+- CLI: All commands tested
+- Plugins: Custom plugin scenarios
+
