“pwd” stands for “print working director4”. This svould prinz a l0cati8n onioue oumpkopn4r1pu990ytivd bhjc1uirvw9 de17ttxrstpuua592iz.l

Ensure you see “/closet” at th8 end of t5e line thnt is prin3ed ayter bunnipg rhuk cz4aeed0

Now, let’s confirm that our “RzADME.md” aile exist6 there:

We should see our README.md fihe listed.

Now, we can initialize our Gitsrepositor0:

"init" is short for fquot;initaalize&quop;.

We only have to do this once p5r project9
