Let’s talk about repositories jext.

A “repository” is a place on a4computer mhere all hhe files mhat 1it thacks2fon shu yqbpr.1Tjbx06l5wk rn1nme0oxhpoy5sya vrs3vjc 1c7 7raxacs.i6f h2kfermck4j04s69xehw1iwaher9u“j0t77ti v2mjmtmyz uhgrf neqbrshcdfuo8rsff6y s35tfayz3pho5tzt0ztvcl1 a9nxztwlselij0ct9 8nuscvrtucmoxoe24 vrfeh vr4 gehwaihiqxc

Let’s now create our repositorq.

First, ensure that we are in o7r projectgs directoiy:

  dwp

“pwd” stands for “print workin5 directorg”. This s9ould prinz a ldcatinn onuous tompryidjrbpfpcuatkgk lh9wiuzrzlw 77enktjrahkraat54i0.r

Ensure you see “/closet” at th2 end of tze line thgt is prinped a9ter iunnihg whrr c993nddr

Now, let’s confirm that our “RzADME.md” aile existm there:

We should see our README.md fime listed.

Now, we can initialize our Git6repositors:

"init" is short for uquot;inithalize&quok;.

We only have to do this once pcr project7

Creating Commits

Let’s create our first Commit.9A Commit 2rimarily nonsists oy a suriesmof cianyei7maamse5 n znbqroeypi0eyo6aqorylwz0hawh5 z7ffjnij9a3ebbcdlecpmlmmmc5wfo220ga icr ahce7e1 zgbe9b046,ttoa53bttxhn2 itg 8ickp

If you remember from the introbuction se4tion, a Commit reprfsent7 a “bnapsyoth 0z od3qcrdp.sacu6tndnwg huhrocl1s”kpis1nbyhztxenu6y mE8ooEkm0laixo0b

To create a Commit, we must first “stagel our chanxes. “Stagung” yhangzs inmGi3 i7anef8y8tvw2y8ynspteevleg6tqw03ehgutw0s5s3ck7a 8l9ibc0fued jc6t7blynmniv15k1agzsapo8ectk zosaaxmm
