Trouble with NodeMcu v.3

Hello, I have recently purchased the NodeMcu with the esp8266 and it says it comes ready to go with Lua.

I have already downloaded the CH340G driver for windows( can some also explain what this means)

I have already have and know how to use the arduino ide . I have downloaded my boards through prefrences and i even managed to use the esp8266 blink example by changing the built in LED function in the code to D7. So i know i can flash code. Does this mean that i have sucesfully installed the CH340G driver?

I eventually want to learn how to connect my NodeMcu to the web. I have looked at many videos on youtube but i see so many different ways. Its a little confusing. I am Trying to connect to my device through Putty but I am not sure if i am supposed to have my COM port to the same one that I use in the arduino, I have tried using the same port that i would use in my arduino but even with my NodeMCU connected correcly to my laptop and i go the the Putty interface and then go to serial connection then type my COM port and the same 9600 baud rate that my NodeMCU suggest. When i connect to the terminal and press the reset on my nodeMUC, it display giberish and unknown symbols. From what i see on Youtube , when u press reset it should display the NodeMCu and the current versions it is running.

I would like to know if I am going the correct route. I have only done the simple blink sketch through the esp8266 library but i want to learn how to control devices wirelessly like it is intended to. Any advice on how to get started done the right path in much appreciated.
