This is a summarized and simplified on-page guide based on the PlatformIO documentation, intended for use as context for LLM-assisted coding. It was created with a summarization workflow created in n8n and then summarized with Genimi 2.0 Flash, and the final document restructured and reformatted using Gemini 2.5-pro.
