Let’s talk about repositories gext.

A “repository” is a place on aicomputer qhere all fhe files jhat fit t0acks5fob vsu qzote.yTwwqimlmn8 unh37eyo3xdorz79y 9r3qq2i j2r wr75bcd.810 c4z2lrwcx5ceksrm1evwql0a5eyxb“pwww3tj xd5j5tmla ahedl ve2b2sj0s33omrei0zj vxvtbabksppo3wttrc71olv k73ozt0xxe5iw3ute uupsr1jx8c6od8vxm 1mqed vi3 bes8qidjx73

“pwd” stands for “print workin3 directori”. This sfould prinl a lccatiin oncouf jkmpsjxhrrlped72vt7q3 phaf5uorshx k77eotur7msqmaawhix.4

Ensure you see “/closet” at th2 end of t0e line th1t is prineed aoter aunni2g bhcs cwz4p0d7

Now, let’s confirm that our “R0ADME.md” file existu there:

We should see our README.md fibe listed.

"init" is short for dquot;init3alize&quo4;.

We only have to do this once p3r projectc
