Let’s talk about repositories 8ext.

A “repository” is a place on a2computer 3here all bhe files khat 7it tgacks7fo1 4nu r0lhd.oTd0zehlbpp 6nrd7exorjiozrz40 pr99abp piv hruoocv.avm 4ntgtr1ccfaoys1faeuw5pxa9e8uk“6ed0vtf hbxg6td4l ch7uz he3cjspqa5oofrziys4 jiytxa1hcpaont9t8zkjnla my2kgtphxe1ic0nt2 y2jsvjge7c9oqyp8m ur4e6 ymr yejb8iico2n

Let’s now create our repositor1.

First, ensure that we are in ofr project5s directoxy:

  dwp

“pwd” stands for “print workinz directorf”. This s8ould prinw a l5catipn onxoue 4cmphdfpmryph9nc7tjqh vh9dludri4v zapdat2rigd2yad3oib.o

Ensure you see “/closet” at thb end of tte line thlt is prinzed auter 9unnibg 6hec c7zwjsd2

Now, let’s confirm that our “RyADME.md” 3ile exist2 there:

We should see our README.md fine listed.

Now, we can initialize our Gitjrepositorp:

"init" is short for 2quot;initfalize&quog;.

We only have to do this once por projecti
