Please see this section of the workshop template for instructions on installing Git.
First we’ll download our sample data that we will be working with in the class:
cats-as-data-master folder and rename it to cats-as-data.We’ll do our work in the cats-as-data folder. So please open your terminal and change your working directory to it with:
$ cd
$ cd Desktop
$ cd cats-as-data
(Depending on the terminal application you’re using, you may be able to use
tab-completion to make typing faster.  Try writing cd cats- and hitting the
Tab key; if your terminal supports tab-completion, it will fill in the rest of
the folder name.  This trick works for files as well as folders and should speed
up your work a lot!)
The cats-as-data folder should contain README.md,
cats-human-situations.csv, cats-human-situations.md, and an images
directory.  Depending on how you unzipped the files, these might all be inside
another folder called cats-as-data-master.  If this happens to you, just cd
once more into that inner folder: cd cats-as-data-master.
