3. Configuring Git
+ +Configuring from the Command Line
+
+
+
+git config --global user.name "Ada Lovelace"
+git config --global user.email "ada@lovelace.io"
+git config --global core.editor "emacs -nw"
+git config --global init.defaultBranch main
+Help with Config
+
+
+
+git config --list
+git config --help
+cat ~/.gitconfig
+Current Config ~/.gitconfig
++[core] + editor = emacs -nw +[init] + defaultBranch = main +[user] + name = Ada Lovelace + email = ada@lovelace.io ++
4. Networking Activity
+
+
+Working Example
+-
+
- We are going to create a "database" or repository of people you've met at the summer school +
- We will track changes using git and keep it all on GitHub +
- The following slides are simple instructions that you need to work through, follow along with me! + +
Activity: Make Friends
+-
+
- Create a new file to track your friends, including first name and institution
+
-
+
- I am Elsa from Lawrence Livermore National Lab + +
+ - Start tracking this file with Git +
- Put this on GitHub +
- Talk to your neighbor and add them to your file
+
-
+
- don't forget to commit your changes + +
+ - Talk to a different neighbor and add their information +
- Add hobbies to your entries + +
Activity: Friends Challenge
+-
+
- Open just your text editor on your laptop +
- Swap laptops with a neighbor +
- Make a change (addition and/or deletion) to the file in front of you +

- What changed?? + +
Watch me!
+-
+

- Commit changes in separate hunks + +
5. Continue Your Journey

+
+This is just the beginning
+-
+
- More things to learn:
+
-
+
- branching +
- collaboration through "pull" or "merge" requests +
- platforms: GitHub and GitLab + +
+
+
Git Hosting Services
+-
+
