+#include <functional>
+#include "TaskManager.h"

+    void sendHeartbeat() {

 ### Adding Custom Tasks
 
-To add custom tasks to your SPORE system:
+#### Method 1: Using std::bind (Recommended)
+
+1. **Create your service class**:
+   ```cpp
+   class SensorService {
+   public:
+       void readTemperature() {
+           // Read sensor logic
+           Serial.println("Reading temperature");
+       }
+       
+       void calibrateSensors() {
+           // Calibration logic
+           Serial.println("Calibrating sensors");
+       }
+   };
+   ```
+
+2. **Register with TaskManager**:
+   ```cpp
+   SensorService sensors;
+   
+   taskManager.registerTask("temp_read", 1000, 
+                          std::bind(&SensorService::readTemperature, &sensors));
+   taskManager.registerTask("calibrate", 60000, 
+                          std::bind(&SensorService::calibrateSensors, &sensors));
+   ```
+
+#### Method 2: Traditional Functions

 ### Task Configuration Options
 
 When registering tasks, you can specify:
 
 - **Name**: Unique identifier for the task
 - **Interval**: Execution frequency in milliseconds
+- **Callback**: Function, bound method, or lambda to execute
 - **Enabled**: Whether the task starts enabled (default: true)
 - **AutoStart**: Whether to start automatically (default: true)
 
 ```cpp
+// Traditional function
 taskManager.registerTask("delayed_task", 5000, taskFunction, true, false);
-// Creates a task that's enabled but won't auto-start
+
+// Member function with std::bind
+taskManager.registerTask("service_task", 3000, 
+                       std::bind(&Service::method, &instance), true, false);
+
+// Lambda function
+taskManager.registerTask("lambda_task", 2000, 
+                       []() { Serial.println("Lambda!"); }, true, false);
 ```
