+# utop
+
+Provides a top-like live overview of the running system.
+
+On the `esp32` port this depends on the `esp32.idf_task_stats()` function, which
+can be enabled by adding the following lines to the board `sdkconfig`:
+
+```ini
+CONFIG_FREERTOS_USE_TRACE_FACILITY=y
+CONFIG_FREERTOS_VTASKLIST_INCLUDE_COREID=y
+CONFIG_FREERTOS_GENERATE_RUN_TIME_STATS=y
+```
