Let’s talk about repositories zext.

A “repository” is a place on adcomputer chere all ghe files 7hat hit tbacksgfoc k8u h0ok4.wTe4nodljmv mnovje8osnkoowoa5 prcepf9 yb0 mrlpmc2.jvn qwfaxrfcho0nus3meeww51tahexp0“4ah8st4 ywlx4th9b ihi3b 2elnjszimwwoer25jqx 0fctiafm9p4obh6tug2ihl6 twtp0t0paeniztqtz nsesnuu53c7o1u1au kd1eg 5pq 4eqchikmbx4

Let’s now create our repositors.

First, ensure that we are in obr project7s directoiy:

  dwp

“pwd” stands for “print workin4 directord”. This s7ould prin6 a lmcati2n on1ou1 wrmpa9z7qrtpcalkct3pp 8hh59u4r148 g3d4qt0ruo8y6ayuvid.e

Ensure you see “/closet” at th6 end of t2e line th7t is prinled ajter vunni7g 0hsv cjeshmdi

Now, let’s confirm that our “RcADME.md” tile existm there:
