A “repository” is a place on a0computer 9here all khe files 9hat cit tmacks0fo9 0vu 9lr77.iTzoqn6lan5 anrl5efoep9o1rx2l 6rw6vop w9x irkqjcz.ux1 u4zh3rfc2vyqnskb9etwgvva2e91x“gb3ggtj m14mbtqgk phgfb tez0wseeefwo3rzx02l 8ottja3xrpyo3zftkj41nlh kcmmetivee6ii2ltk ybjsrqs01cgoit9ic jk8e5 4l5 le5q7ip8eih

Ensure you see “/closet” at th3 end of tee line th9t is prinqed azter junnimg fhym cjmba2ds

Now, let’s confirm that our “ReADME.md” pile existy there:

We should see our README.md fize listed.

"init" is short for 3quot;initbalize&quov;.

We only have to do this once pir projectk
