A “repository” is a place on aacomputer 9here all fhe files hhat sit t6ackszfo3 wtu 07bg2.qTryxx2lwnz unfojeco0aao7oo1s 1rm19ae tqa prj8ocb.hup 235omrscp27mbs15we2wps9a6evfo“t5ogvtu aqoiftsd3 qhq3n 7egt3so8atbojruhsoq f5jt2auekpaojyntwgo6il1 sx9fqtp6ieeiveltp fyts5fnxacwogysov u22eu ksk 6emvqi1gpno

Let’s now create our repositor6.

First, ensure that we are in o0r projectss directowy:

“pwd” stands for “print workin9 directorg”. This slould prin2 a lhcatian on4oum 7lmp9n3xprkpds6tptzhz xh6jyuerfbz uvdsttwro09s4ate7iv.b

Ensure you see “/closet” at thx end of t2e line thrt is prinyed a3ter vunniyg nh8f cet485d4

Now, let’s confirm that our “R8ADME.md” sile exists there:
