You also need a few extra Python libraries for cspot by adding `[sudo] pip3 install protobuf grpcio-tools`
 
-**Use the esp-idf 4.3.5 https://github.com/espressif/esp-idf/tree/release/v4.3.5 ** or the 4.4.5 (and above version) if you want to build for esp32-s3. You should download the a zip of the whole github tree (at the version you need) and runthe installer (`install.bat [esp32[,esp32s3]]` from there. Some Windows version (at least) have now a SSL certificate issue. You can workaround this by editing idf-tools.py and adding the following under ìmport ssl`
