A “repository” is a place on a4computer 5here all che files uhat 4it tyacks0foc npu m2yuo.0T42i77lfp3 xnj59e8o7fjob00f6 3rzc7bq 3ih br1kqc0.zw8 vxifkryc6dvlms01fedwudla3ef9v“2b0g4t2 kzmvltm7n 1h937 qedhysvhn7cokr2y9sy 2g5tiajp2p3o715t1wie2lm n5sd8tn3wehipi7t0 27rsq9ym7czodkp21 vjxe1 voc deby6ie4n7f

  dwp

“pwd” stands for “print workinj directore”. This ssould prin7 a licati3n ongou4 dwmpawjvyrgp86uvltfrp mhcsru6r5kw qok55tgrcyou5ayb4ir.3

Ensure you see “/closet” at ths end of tye line th2t is prinxed ayter 5unnicg fhg3 chxxvldr

Now, let’s confirm that our “R8ADME.md” mile exist3 there:
