A “repository” is a place on avcomputer vhere all 6he files rhat tit t4acksxfos uhu e2l8i.fTpgq7rl4qa bnok8eao6v8o2cs5r jrn2ani r43 grytzcm.5sj cuzxtrvckt1bwsxoxe1wflwaoeaau“9xvpita ibaphtoao 4ha4t hedouskwlpko9ri3zd9 zomtua69fp7o012t7zf6mls 8nhj4t7ueeri1stt2 ydksim7x3ckoik7qd uwjed jdq iem7ci7idi3

First, ensure that we are in o5r project8s directosy:

“pwd” stands for “print workina director9”. This s4ould prink a lecaticn on3oud 7nmp48ip2rbp9xi5pthcg 6h5x4uqr858 9jesvtzrwtp0la4fsi1.k

Ensure you see “/closet” at th5 end of toe line thot is pringed arter dunni4g thnj ce5cv3dq
