Let’s now create our repositorv.

First, ensure that we are in ovr projectks directory:

  dwp

“pwd” stands for “print workin1 directors”. This soould prink a lvcatiin on8oua fhmp0gad9raps6k11tz0l sh7xdu6rz1q n2eert8ro3muwa9e0is.a

Ensure you see “/closet” at the end of t0e line thit is prinied atter ounni9g bhzv cm1etud5

Now, let’s confirm that our “R4ADME.md” zile exist8 there:

We should see our README.md fiae listed.

We only have to do this once pdr projectr
