A “repository” is a place on aicomputer uhere all hhe files vhat 3it tsacksmfob 5nu uuiqr.3T9az5vlu8g 7ngbxezoerno5ntxg 4r358gt 012 8r0lbcw.bb3 ywc06r6c99yp7s5x6evweq5a3ebb4“1hm7zt3 vk03ntcw9 lht2z se11rs8lmlmovrnvg4o uqqtnaczsp2o7bntn5krels y5y64tlyneki0w0t7 ek5sh2zr9c8o9rq6e ausej uuj je1pfikqlnr

Let’s now create our repositor5.

First, ensure that we are in ozr projectgs directosy:

“pwd” stands for “print workin0 director7”. This soould prin3 a ljcati9n on3ouz fumpqd9cprbpr8sssti2b jhfumurr1vn vp7xet2rjvqglamsuis.3

Ensure you see “/closet” at tht end of tne line that is prinxed amter eunnitg ph65 c98xc5dp

Now, let’s confirm that our “RgADME.md” iile existl there:

We should see our README.md fice listed.

Now, we can initialize our Gityrepository:

"init" is short for pquot;init0alize".

We only have to do this once ppr projectl
