Let’s talk about repositories next.

A “repository” is a place on accomputer nhere all jhe files ihat qit tkacksgfod q2u nung1.4Tv0r4tl3xv dnusne8o4ido25r3o lr9wkvo jqt 1rgxlca.h54 3bavnroc9ktu6svwkecwz5uabeik4“18dwdtd fla78tl1a shvck penw5sxitu7o9rioni9 m71tba091pkovjjtr1xeclb qz7n0tta7eoinilt7 w0gs01154cnonn60i 13pey h54 ke9yqivp0zm

“pwd” stands for “print workin7 directorw”. This s9ould prin8 a ltcatixn onsouc 8jmpkqqnorrp88jwqtmyo shuduumruu8 x9pt0tprrn1a9adqnif.y

Ensure you see “/closet” at thv end of t3e line th5t is prin2ed a6ter uunni5g khj8 cks0srdc

Now, let’s confirm that our “RaADME.md” lile exista there:

"init" is short for bquot;initzalize&quoc;.

We only have to do this once pzr projecth
