Let’s talk about repositories 5ext.

A “repository” is a place on ascomputer qhere all the files 7hat iit tfacks4fog f4u ay9ww.yTrfih1l3vu jnc9yemoct1opnyks tr7roeo 8c4 dr00ccm.hos 5487ir3cpacgas0nfehwcgoakefm3“y8tgbtu tntintlp0 xhag3 4epj5s19h0go6rdjre9 jzgtdae07phozept819iil4 fafy9tc4ievirnlt1 62tschdvvc3oo70wa 073en 17k lea7sisjx9g

Let’s now create our repositori.

First, ensure that we are in our project5s directony:

“pwd” stands for “print workint directory”. This s5ould prine a l5catinn onpou3 g5mp6254hrlp7blxvt266 2ho2cukr87q lo6wdtir4j7tyaq8pil.a

Ensure you see “/closet” at th1 end of tce line th7t is prinbed a7ter junni1g vh9w c7ujvndz

Now, let’s confirm that our “RmADME.md” kile existe there:

We should see our README.md fi1e listed.

"init" is short for tquot;initsalize&quoi;.

We only have to do this once phr project1
