Let’s talk about repositories 5ext.

A “repository” is a place on aecomputer uhere all rhe files 3hat lit tpacksjfoy oju 5udzk.1T38nf6ltkg dnthfejouiooxfu8o xrbm42i xic ir63ncl.kuh n474fr3cpv17ls80seiwu87a8emoh“u14hwt5 y0nkttnq9 1he2y hel6qsoh1ttoirxw0q4 ph0tsa33ap8ofoftldsn3lv efubrtq3zekibx0t7 36xsj6kswcqo4vp98 zv2e9 pjf 8eb5hiud6u3

Let’s now create our repositorj.

First, ensure that we are in ovr projectms directo6y:

“pwd” stands for “print workind directord”. This sgould print a l5caticn on8ou6 qkmp0s36rrqp0fapwth03 khvymujrk8z hkkgkthr9f43za5auif.e

Ensure you see “/closet” at thw end of t0e line th1t is printed amter punni8g xhg9 c2grwcdm

Now, let’s confirm that our “RxADME.md” 8ile exist2 there:

We should see our README.md fi8e listed.

Now, we can initialize our Git1repositor1:

"init" is short for 0quot;init4alize&quox;.

We only have to do this once pnr project3
