 # TDengine driver connector for Lua
 
 It's a Lua implementation for [TDengine](https://github.com/taosdata/TDengine), an open-sourced big data platform designed and optimized for the Internet of Things (IoT), Connected Cars, Industrial IoT, and IT Infrastructure and Application Monitoring. You may need to install Lua5.3 .  
-
+As TDengine is built with lua-enable, the built-in lua module conflicts with external lua. The following commands require TDengine built with lua-disable.  
+To disable built-in lua:  
+mkdir debug && cd debug  
+cmake .. -DBUILD_LUA=false && cmake --build .
 ## Lua Dependencies
