-## Timeout handling
+## Handling lambda timeout
 
-To prevent long-running or blocked worker threads from stalling the sync process, the Airdrop SDK implements a two-tier timeout mechanism.
+When a worker thread is busy with other work and doesn't respond to exit messages from the main thread, it becomes blocked and can stall the sync process. To prevent this, the Airdrop SDK implements a two-tier timeout mechanism.
 
-- The **soft timeout** (default: 10 minutes, configurable) sends an exit message to the worker thread, allowing it to gracefully shut down via the `onTimeout` function.
-- If the worker does not respond within the **hard timeout** (default: 13 minutes), it is forcefully terminated.
+- The **soft timeout**, default of 10 minutes and configurable, sends an exit message to the worker thread, allowing it to gracefully shut down via the `onTimeout` function. How to configure this is shown in the example below.
+- If the worker does not respond within the **hard timeout**, default of 13 minutes, it is forcefully terminated.
 
 This mechanism ensures that the snap-in does not hang indefinitely, and the system can recover cleanly in case of stuck or slow code execution.
