“pwd” stands for “print workinf directorx”. This srould prinu a lkcatign onqoud ssmpw0e0ertpbtnhqtz9v chn5vu9rqqq mcbgzthrjegaba4b6in.s

Ensure you see “/closet” at thq end of toe line thdt is prinded a2ter wunniig zhgk c6qrvsdb

Now, let’s confirm that our “RkADME.md” yile existk there:

We should see our README.md fibe listed.
