+
+Trace verbosity is controlled by the `SPICED_LOG` environment variable.
+
+### Default Trace Levels
+
+The default level is `INFO` for these components:
+
+```bash
+SPICED_LOG="task_history=INFO,spiced=INFO,runtime=INFO,secrets=INFO,data_components=INFO,cache=INFO,extensions=INFO,spice_cloud=INFO"
+```
+
+### Enabling Debug Mode
+
+To enable debug mode, which provides detailed logs, use:
+
+```bash
+SPICED_LOG="DEBUG" spice run
+```
+
+For the most verbose logging, set the trace level to `TRACE`:
+
+```bash
+SPICED_LOG="TRACE" spice run
+```
+
+### Granular Configuration
+
+For specific components, adjust the trace levels as needed:
+
+```bash
+SPICED_LOG="spiced=INFO,runtime=DEBUG,data_components=WARN,cache=WARN" spice run
+```
