error message, in new please help!

Hello all, I tried to copy and paste someone elses code into a sketch and I got this error message! Can someone please help!

Arduino: 1.6.7 (Windows 10), Board: "Arduino/Genuino Uno"

C:\Users\micha\Downloads\voltage_and_current\voltage_and_current.ino\sketch_mar04a\sketch_mar04a.ino:11:21: fatal error: EmonLib.h: No such file or directory

#include "EmonLib.h"

^

compilation terminated.

exit status 1
Error compiling.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

Where did you put EmonLib.h when you downloaded it?

How did you install the library?

If that library is installed as a library, include with <> instead of "". You use ""s if the thing you're including is in the sketch folder.

If it's not installed as a library and isn't in the sketch folder, you need to do one of those things.

can someone help me!? have this error
