 # ESP-IDF Release and SoC Compatibility
 
-The following table shows ESP-IDF support of Espressif SoCs where :yellow_circle: and :green_circle: denote preview status and support, respectively. In preview status the build is not yet enabled and some crucial parts could be missing (like documentation, datasheet). Please use an ESP-IDF release where the desired SoC is already supported.

 # ESP-IDF 与乐鑫芯片
 
-下表总结了乐鑫芯片在 ESP-IDF 各版本中的支持状态，其中 :green_circle: 代表已支持，:yellow_circle: 代表目前处于预览支持状态。在预览支持阶段，因为新芯片尚未完全添加到构建系统目录，所以一些重要的内容（如文档和技术规格书等）可能会缺失。请确保使用与芯片相匹配的 ESP-IDF 版本。
