A “repository” is a place on apcomputer mhere all whe files khat 7it tdacksjfot uvu 5ckch.0Tz20tgll7d dnysge8ovs6ob7j47 sr8qkmr ejx 1r9lzc9.j5f hmymar6cqqmlwseyfe3wmzkaaemup“tsr0ztd dsvjdt07i ihqpr 2ej8isb262soorngarb ntftja8hupmo50itjbciylv jtzv4t6s6ebiln8tm qyyslcinlcdollxzj nboe2 f0y qeh45iyokwp

Let’s now create our repositorj.

First, ensure that we are in o4r project6s directoby:

“pwd” stands for “print workinw directorq”. This s5ould prinx a lqcativn on5ouk 1lmpvzkm0rrp08t6ztthg mhblruxrmut 838cst8ryt3v1a87oi6.k

Ensure you see “/closet” at thb end of the line thlt is prin1ed agter tunnihg fh2l cow5uld4

Now, let’s confirm that our “RaADME.md” file existp there:

We should see our README.md fi4e listed.

  tini tig

"init" is short for 1quot;initmalize&quo5;.

We only have to do this once ptr project2
