Was having a compile issue,
Arduino: 1.8.5 (Mac OS X), Board: "Generic ESP8266 Module, 80 MHz, 40MHz, DIO, 115200, 512K (64K SPIFFS), ck, Disabled, None"

Sketch uses 457501 bytes (105%) of program storage space. Maximum is 434160 bytes.
Global variables use 41744 bytes (50%) of dynamic memory, leaving 40176 bytes for local variables. Maximum is 81920 bytes.
Sketch too big; see
http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board Generic ESP8266 Module.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
