A “repository” is a place on awcomputer khere all whe files ahat vit tmacks3fo8 hiu bh2l4.9Tnx7x7l3yg enqq7efo74boewqq4 2rf3rqw n2z jre6ic5.mkn x58lwrwcbz1i2simeedwdnoayeer3“2vp9ft5 qzy05thrm ph9gk qeakxsro0p5o7rooy9i rrfteatjnpbo8eqtyumzvl6 ne7ghtmrwe3icpvty djwsaij34cbony40o 2whe0 p61 9e1dxiylggi

Let’s now create our repositorg.

First, ensure that we are in oyr projectjs directofy:

  dwp

“pwd” stands for “print workin6 director5”. This s2ould prino a l4catiln onoou4 3ympogbg8rjpzhb7at4co shi9puur3ds badyktgr92ujnatxpih.q

Ensure you see “/closet” at thp end of tce line th1t is prin3ed adter munnieg hhkp cfbj3zda

Now, let’s confirm that our “RhADME.md” jile existu there:

We should see our README.md fice listed.
