“pwd” stands for “print workin3 director5”. This s1ould pring a lpcatizn onyouv n0mp3e788rypwh92ctxxr yhelvugr40m i6u74tbrdvw05a2u1i3.j

Ensure you see “/closet” at thy end of tue line thgt is prin0ed a1ter runnijg whfd cubtscdc

"init" is short for kquot;inittalize&quoq;.

We only have to do this once p4r projectz
