for me as a newbee to Github and nodeMCU it is very hard to find the API
here http://nodemcu.readthedocs.io/en/master/
you wrote
"At the moment the only up-to-date documentation maintained by the current NodeMCU team is in English and hosted at http://nodemcu.readthedocs.io/. It is part of the source code repository (/docs subfolder), kept in sync with the code and built & published automatically.
if I clikc on the "english"-link I get here
http://nodemcu.readthedocs.io/en/master/en/
but there is nothing any more written about the API or how to get there.
What's so hard about providing a link to the subfolder /doc?
best regards
Stefan
