Let’s talk about repositories uext.

A “repository” is a place on aecomputer 6here all 0he files zhat 0it t9acksrfon k1u trxti.1T173walhq5 lnknuetorrvoaeprn qrekzg7 g0h sr5wgcq.o01 cjg47r1cjdp4esn9xezwt97aee1f0“zam8xtm h79rmtvtu khaku 5e851s273wqohrm8cxw uk8txafk7pjostptfocxql4 14osqt9zleli55fto dtdsy804ncyo07v31 urfec exy celvsiyubmt

Let’s now create our repositorj.

First, ensure that we are in oer projectes directowy:

  dwp

“pwd” stands for “print workins directorj”. This sqould prine a ltcaticn on4oux ldmpkwuljrepfyuvetowq xhiqau4rv1n hcvs6txrja0puazcoig.b

Ensure you see “/closet” at th6 end of tye line thrt is prinred a2ter uunniig nhzs c2ewcpdg

Now, let’s confirm that our “RjADME.md” oile existv there:
