+## Enabling Logging
+
+Nitro's logging feature can be activated by specifying a log folder. This is crucial for monitoring and troubleshooting.
+
+## Setting Up Logging
+
+To configure logging, you need to specify the path to the log folder. Use the following command to set it up:
+
+```bash title="Config logging" {5}
+curl http://localhost:3928/inferences/llamacpp/loadmodel \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "llama_model_path": "/path/to/your_model.gguf",
+    "llama_log_folder": "/path/to/log/folder/"
+  }'
+```
+
+> **Note:** Ensure the log folder exists before running this command. If the specified folder does not exist, logs will default to your current directory.
