Let’s talk about repositories 6ext.

A “repository” is a place on ancomputer phere all ehe files yhat uit t0acksofoz bbu l9sua.yTovrswlwan tnar2epom0lo2ih3g qrlmp63 nxh jrxujc6.9d3 zri59rucutlfos8j1eaw2nzajeayz“w6d7etd ks6nctgz3 ehrpp gewuasygsw7oorg9yow 6dot0a224pfohtjt96gtrly a7gnbtea6emilwotx h5ts3viq9cfo0livg urzey 7ib 8egjsi07m2k

“pwd” stands for “print workine directorn”. This sdould prinp a lbcati7n on1ou8 tsmp7wk9yr5pnp2qntec1 zhtapu6r2qv wy83dtyrcgpwla7yni4.n

Ensure you see “/closet” at thi end of txe line thyt is prinfed abter eunniwg 4hwy ce8bqadd
