The issues list on GitHub is not the right place to ask for help. Use it to report bugs and to place feature requests. "how do I ..." or a "I can't get this to work ..." should be directed to StackOverflow or esp8266.com.

StackOverflow

StackOverflow is the perfect place to ask coding questions. Use one or several of the following tags: esp8266, nodemcu or Lua.

esp8266.com Forums

esp8266.com has a few NodeMCU specific forums where a number of our active community members tend to hang out.
