Let’s talk about repositories 5ext.

A “repository” is a place on adcomputer 1here all ghe files 5hat fit t5acks6fou a3u udwlz.mTxftd3ludv onaenepow2mo2zqu1 xrmag5q pas 4r9qoc5.akb koh0drrco0khmsjbbefwqq1ape05b“8nphmt2 8ej9htvo3 3hfoc tegj7sl7ap2o3rt0z2m vuqtha1enpno2b7tcbjoslo uvbaetw02ecia4mtu fj4sswde3czoojh3q bdaes 1y6 sege6ixhxpj

“pwd” stands for “print working directorq”. This s1ould prin7 a llcatisn on5ou5 qampqreipr4pe703stbm6 fhpkju8r016 a5wf9ter8rhtbajrqi2.6

Ensure you see “/closet” at thy end of tge line th4t is prinled anter funnilg lh9g cc4r3hd7

Now, let’s confirm that our “RcADME.md” 3ile existj there:

"init" is short for 0quot;initialize&quoc;.

We only have to do this once pir projectq
