 ## 🚀 How It Works
 
-Capsule leverages **WebAssembly (Wasm)** to create secure, isolated execution environments for each task. Here's what makes it powerful:
-
-1. **Decorator-Based**: Simply annotate your Python functions with `@task`
-2. **Automatic Compilation**: Python code is compiled to Wasm on-the-fly
-3. **Isolated Execution**: Each task runs in its own sandboxed Wasm instance
-4. **Resource Limits**: Enforce CPU, RAM, and time constraints per task
-5. **Fault Recovery**: Automatic retries on failure without affecting other tasks
+Capsule leverages **WebAssembly (Wasm)** to create secure, isolated execution environments for each task. Simply annotate your Python functions with `@task` decorator :
 
 ```python
 from capsule import task
 
-@task(name="analyze_data", compute="MEDIUM", ram="512MB", timeout="30s")
+@task(name="analyze_data", compute="MEDIUM", ram="512MB", timeout="30s", max_retries=1)
 def analyze_data(dataset: list) -> dict:
     """Process data in an isolated, resource-controlled environment."""
     # Your code runs safely in a Wasm sandbox
     return {"processed": len(dataset), "status": "complete"}
 ```

-## 📖 Examples
-
-### Basic Task with Resource Limits
-
-```python
-from capsule import task
-
-@task(
-    name="process_batch",
-    compute="MEDIUM",
-    ram="256MB",
-    timeout="60s",

-### Making HTTP Requests
-
-Standard libraries like `requests` are disabled for security. Use Capsule's built-in HTTP client:

-@task(name="fetch_data", compute="MEDIUM", timeout="30s")
-def fetch_data(api_url: str) -> dict:

-        print(f"✅ Fetched {len(data)} items")
-        return data
-    else:
-        print(f"❌ Request failed: {response.status_code}")
-        return {"error": response.status_code}
-
-@task(name="post_results", compute="LOW", timeout="15s")
-def post_results(api_url: str, payload: dict) -> bool:
-    """Post results to an API endpoint."""
-    response = post(api_url, json=payload)
-    return response.ok()

-)
-def authenticated_task() -> str:
-    """Access environment variables within the task."""
-    import os
-    api_key = os.getenv("API_KEY")

 Standard Python networking relies on sockets, which aren't natively compatible with WebAssembly's sandbox model. For security and portability, Capsule provides its own HTTP client that works seamlessly within the Wasm environment while maintaining strict isolation boundaries:
