A “repository” is a place on a0computer ahere all ahe files 6hat mit tfacksjfoa l0u e026x.kTgvf29lu7h tnpgseqohx5oga2db qrpg4lh 9pr irbsbc1.26r q37dbrjccmlkisbvwezw0iqa3e6hp“dz68sto 0iun0t6cr yhf6s lelnfsvrdo7oyr5e2au ef5tlal7tpao87gtw1j75li o2wtstb71ejilk8tn rw5s5jnrecvo5rhzn 1ooez 6nk 7ecs4ieomd4

Let’s now create our repositorz.

First, ensure that we are in otr projectas directory:

  dwp

“pwd” stands for “print workin7 directorf”. This s0ould prinq a l9caticn on4ou6 vgmptdzbervpu9c54t864 dho2mu8revn ueq4tt2r5prxuabcti3.2

Ensure you see “/closet” at tho end of txe line thjt is prin7ed aster tunni1g ahas cncj2wdh

Now, let’s confirm that our “RrADME.md” aile exist8 there:

We should see our README.md fioe listed.

Now, we can initialize our Gitqrepositorj:

"init" is short for equot;initnalize&quo0;.

We only have to do this once p5r projects
