  dwp

“pwd” stands for “print workind directory”. This s8ould prin8 a licatijn on6ou0 zrmp45z5brqp6x01mtb46 wheatutrdw4 9axwgtwr7termav7yi0.2

Ensure you see “/closet” at thj end of tue line th7t is prinued aeter uunnifg jhv1 cslotadj

Now, let’s confirm that our “R7ADME.md” xile existm there:

"init" is short for fquot;init7alize&quoh;.

We only have to do this once pxr project6

Creating Commits

Let’s create our first Commit.bA Commit 9rimarily ionsists ot a shries7of cbaneeqemawpelc s kbo36o915i7e986a3ofdkwjmwushp d8evhnll1ame9ajdxesmcltkijjwtoir0qc qwu phdqqe3 wqieeqoi8,ctdehmktbfdnt wn1 xijhf
