How to get started in Arduino:

Setup driver:
Before you use miniD1 boards, you need setup CH340g driver.

Python:
On Windows you need install Python 2.7.10.
On Linux & MAC OSX, you don't need install it, comes preinstalled with OS.

Installing Hardware package:
There is two ways to install hardware package, Boards Manager or GIT

4.Open Tools->Board:xxx->Boards Manager and install esp8266 by ESP8266
Community (and don't forget to select your ESP8266 board from Tools > Board menu after installation).

Installing with GIT (Recommend):
We recommend using GIT to install Hardware package,you can always get the latest version of it.

Package includes:
1x Mini NodeMCU Lua Wifi Wireless Module
2×Long female pins
