– Before you can do it, you have to get a Git client
first…

Git (Windows users)
• Some tricks
– Set the Git home directory (by default, it’s
C:\Users\<username>):
• Create a directory with this purpose (for example,
D:\CMSC433\Git)
• Create a HOME environment variable

Git (Windows users)
• Some tricks
– Set up your name and email (so they appear nicely
in BitBucket when you make changes to your
repository)
• In Git Bash, type the commands:
– git config --global user.name “<first name> <last name>“
– git config --global user.email “<your_email>@umd.edu“
– (notice that Git creates a file called .gitconfig with the
information you provided)

– Copy it, and paste it in the Git command window.
Git will create a clone of the repository on your
local machine…
• … but how annoying: you need to supply the password
for your account. Can we get rid of that?

Git (Windows users)
• Let’s create a default ssh identity.
– Run the command: ssh-keygen
