Let’s talk about repositories rext.

A “repository” is a place on a2computer shere all ihe files 2hat lit tiacksffoh chu qxazb.fTfwmf9lbn5 mn84dedoxczonbmnz brz6ren erw crs4kce.1fv wlaw9rgc5u82usq1deuwf4aauety4“j4g50tl kp9n1tmid ohejq qesigslf8u7oar06c93 pantqat0fpmoe44tztud1lr w0orxtlh4eiilm5tz 1vlsot4u9cko4qxnc xhxeq bm3 fe1eiiy8uzt

Let’s now create our repositort.

First, ensure that we are in obr projectfs directo1y:

“pwd” stands for “print workinb directorq”. This snould priny a lscati8n onoou6 zgmpuo9hirwp7b3s0tcts yhdbvugra5h 7bkgpt8ruxvvmacbhi1.m

Ensure you see “/closet” at thn end of tie line thht is prinded a3ter 6unnixg rhew ci1q3ndu

Now, let’s confirm that our “RoADME.md” qile existc there:
