Trouble installing Git on El Capitan for Mac

Hello,

I have had considerable trouble with getting to the second step of using the terminal command to return anything but version not found.  It says it is in usr/local/bin but can’t seem to get any further.  I have looked for online help but nothing seems to work. Please advise.  I am a total newbie so I use brackets and just downloaded Xcode.  

Thanks,
Lori
