 The model performance report in Markdown will be available under `reports/stm32-renode-tflite-magic-wand/report.md`.
 The HTML version of the report will be accessible from `reports/stm32-renode-tflite-magic-wand/report/report.html`.
 
+The above two steps (`west build` and `kenning ...`) can be also performed by Kenning automatically using `ZephyrRuntimeBuilder` block, e.g. as in the scenario located in `kenning-scenarios/renode-zephyr-auto-tflite-magic-wand-inference.json`:

 #### Using microTVM
 
 To build the `kenning-zephyr-runtime` app to work with microTVM runtime, set `-DEXTRA_CONF_FILE` to `tvm.conf`, e.g. by executing:

 ## Evaluating a model in Kenning using actual hardware
 
 Kenning can evaluate the runtime running on a physical device.
