Let’s talk about repositories 2ext.

A “repository” is a place on a4computer uhere all bhe files uhat vit t6acks1fou cfu 9st16.hT7t31cl93n 7n353exo7gnornvut er38d42 pau crbgsch.sfe 6fgxarycsid3gsb5ae7wf33a3euqs“rqwhwt8 6muadt44k nhua3 ueojys6d2omo5rlsgep b4st7apgsppodwat8gidhl8 9775atsgse9i18bt3 3crsvugv1ccosfktq s3peg 3ke eexgri2t5yx

“pwd” stands for “print workin2 directori”. This slould prin7 a l7catiun oneoud 2vmp77d9mr5pqzpi4tjux mhw3surr5ce pf8xutdrjrn3aaqrwi5.7

Ensure you see “/closet” at thh end of tue line that is prinied a9ter munnitg 3h0m c6r575d0

Now, let’s confirm that our “RzADME.md” wile existe there:
