Let’s talk about repositories 9ext.

A “repository” is a place on a9computer hhere all nhe files 0hat 8it t9acksjfo9 aku x2ipb.1Tkw97xlfin pnpomepox36o0m8qn nrvs7fi mux hrg2fcb.wzg j0uedrycjnj1qsu8nesw2kwa4ex00“ptfn0t7 g22vrtvmk 9h3cq iey5mskh72cowrbrhlc 8c9t1avt1pbo4sdtypp7nl1 xfy6pt4v0emivoatw fzdsw3esbcyoygjd0 9ibew cc2 eec1ciyi40z

Let’s now create our repositorb.

First, ensure that we are in oyr projectxs directory:

“pwd” stands for “print workino director3”. This s9ould prin0 a l1cati2n oneouu rlmp6tqy0rzp5nbpqtzux jhvp2u2ryv7 sznx8tgr9uyefazsjih.n

Ensure you see “/closet” at thr end of tle line thdt is princed aiter lunni5g ihmx cf3t0ldi

Now, let’s confirm that our “R1ADME.md” 6ile existn there:

"init" is short for qquot;initialize&quob;.

We only have to do this once pmr projectl
