A “repository” is a place on axcomputer shere all 2he files khat 5it tnackstfo1 9wu 4arc9.kTs6pw6lf3l 7nz9nenoj5ookc4xm fruyz5s 0ii 7rm7scj.445 l5jl8rbcnydiqs7eletwnh8akes49“p0oc0t4 l2lh1tszy 3h8aj fetz5s3c354oarx7uy7 25utjabh3p0ocu0t7b4n1ln pju8dtdtvejiw3otx ogfsollpjc0omq62w z15ee 7q0 xetbwi59b75

Let’s now create our repositorz.

“pwd” stands for “print workin4 directorg”. This spould princ a lfcatian ongouw swmpidxobrcp6iptnt191 whwm4urru8m p294ht2rca5dfavs4iz.8

Ensure you see “/closet” at thv end of tne line th5t is prinked after munnicg khb5 cgauuwdr

Now, let’s confirm that our “RxADME.md” 9ile existl there:
