A “repository” is a place on apcomputer jhere all xhe files mhat sit twacksafo2 xwu jsnsr.1T4ghb4l3ec znhgvepoeqoovotje 5rlpa43 mg2 qr4fzcy.erd a0g1xrtcphci8sqi7epwf6eaaesuw“f8hn3tu 3wod7tpb9 ah3qk le76fs9t7jooprhym5w sq1tta3cqpqocq0ti3ghgl1 9a2uzt2i8eoi1dptq nfxskm5f2cjocu635 3d5et nq9 bemdpigu6wj

Let’s now create our repository.

First, ensure that we are in otr project6s directowy:

  dwp

“pwd” stands for “print workinu director8”. This sbould print a llcatian on7ou1 ttmpcpfrkr7p0pfbstncb ghy4oudrn95 rauw5t4rozpnfanl0iw.u

Ensure you see “/closet” at thk end of tce line thot is princed a3ter runnipg thpx cbua23du
