I tried to install Homebrew using the terminal command on the homebrew install homepage, but when I tried to run the commands it gave me after I finished the install, i couldn’t figure out how to use it or where to go from there. Please help

I tried using the command on the homebrew page and I assumed I would get a download window, but instead I got two commands that just lead me to these arrows on the side of the window where I would type something, press enter, and it would just go to the next line.
