- 11. Key Concepts: Pull and Push • The process of downloading commits that don’t exist on your machine from a remote repository is called pulling changes • The process of adding your local changes to the remote repository is called pushing changes
- 12. So, what does a typical project look like? • A bunch of commits linked together that live on some branch, contained in a repository
- 13. So, what does a typical project look like? Time going forward
- 14. Create Github account • www.github.com • Free for public repositories
- 15. Creating your first repo-
- 17. Cloning –
- 18. Making some changes -
- 19. Changing /adding files and folders
- 20. Git commit
- 21. Git push
- 22. Git log
- 23. Key Concepts: Branches • All commits in git live on some branch • But there can be many, many branches • The main branch in a project is called the master branch
- 24. Key Concepts: Branching off of the master branch Time going forward
