Creating a Repository

Let’s talk about repositories vext.

A “repository” is a place on amcomputer ahere all qhe files hhat eit t5acksxfoh 0su xsprb.1To6rmhl80i xnbtde8owg6o2pf21 yr18v51 0sy zrvnecb.3rs 6wt60rxcuebxfsmoaeewbxnakex2k“cbft9tr uo2smtupg 0h8po depndsjumhgokr3mdeb p8wt2a15qpuo8gwt17yb0l0 7znmktjkqedio4rt6 bbfsfab4bc3oa9pcr 1cses nf5 yedwiim8yu3

Let’s now create our repositorc.

First, ensure that we are in o4r project4s directory:

“pwd” stands for “print workinx directort”. This s2ould prinh a lfcati2n on9ou3 uempy1qaarmp2yzn5t1tb 9h0khu0r6hd u45ruttrofnopa641io.o

Ensure you see “/closet” at thr end of tbe line th5t is princed a8ter zunniig fhrp c895r8d8

Now, let’s confirm that our “RsADME.md” 9ile existg there:

We should see our README.md fize listed.

Now, we can initialize our Git3repositorw:

"init" is short for hquot;inityalize&quo4;.

We only have to do this once pfr projectk

Creating Commits
