How Global .gitignore Works in Git

Global .gitignore builds on Git's model of snapshots and references. Every commit points to a full snapshot of your project, and branches are simply lightweight pointers to commits.

Most Git work revolves around status, add, commit, and push.

• The working directory, staging area, and repository are Git's three main areas.
• Commits are immutable snapshots linked to their parents.
• Branches and tags are just pointers to commits.
• Remotes are copies of the repository you sync with.
