+1. Building for Arm based systems such as the Raspbery Pi 4 should use pregenerated files since there are currently no pre-built zap Arm Linux binaries. To understand about code generation and pregenerating code files see [Code generation](../code_generation.md#Pre-generation). To build and install the Python CHIP controller with pregenerated files use the --pregen_dir (-z) argument:
