"RTFM" stands for "Read The F***ing Manual," which means before asking questions or seeking help, you should first attempt to read the instructions or manual.
Imagine you've received a new toy or game, but you don't know how to use it. If your parent says "RTFM," it means you should first try to read the instructions that came with it before asking questions. This is because the instructions often answer common questions and explain how to use the toy or game.
Similarly, in the world of technology, when someone says "RTFM," it means that you should first try to read the manual or instructions for the product or program you're using. This saves time and effort because the information you're seeking may have already been explained in the manual.
So, the next time you're using a new product or program and someone tells you to "RTFM," remember that it means you should try to find the answers in the manual first before asking for help.
