How to add resistor to data pin 4 or gpio 2

my esp8266 dosent boot which is what i have found from the wled faq page. The solution is to add a resistor. But I am totally unaware about how to wire the resistor. Can some one please show me a picture or a link to how to wire or solder the resistor.

Thanks for the help

It says…

please try adding a 3.3 or 4.7kOhms resistor between the data pin and 3v3 pin

So, you would connect one end of the resistor to your data pin and the other to 3.3v.

Thank you soo much for your reply.

So i will have to solder the ends on the back of my esp. Sorry for the very basic question but i couldnt find anything over the internet and I dont know how it works.
