Just installed the esp core off of https://github.com/esp8266/Arduino using the "git version" because there was some file missing when installing using board manager. However, the esp board does not show up under "Tools/Board:", neither do the esp examples, which should show up under file/examples in the arduino IDE.
Any ideas?
Go to File->Preferences Enter this value in Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json
