 The `install.sh` step only needs to be done once. You will need to source
 `export.sh` for every new session.

+please ensure you are using the following required IDF versions:
+- ESP32-S3 currently requires latest `master`, but eventually `v4.4` or later when
+  it's available.
+- ESP32-S2 and ESP32-C3 require `v4.3.1` or later.
