What is a repository?

• A repository is usually used to organize a single project. Repositories can contain folders and files, images, videos, spreadsheets, and data sets -- anything your project needs. Often, repositories include a README file, a file with information about your project. README files are written in the plain text Markdown language.

What are branches?

• By default, your repository has one branch named main that is considered to be the definitive branch. You can create additional branches off of main in your repository. You can use branches to have different versions of a project at one time. This is helpful when you want to add new features to a project without changing the main source of code.

• Have you ever saved different versions of a file? Something like:

  • story.txt
  • story-edit.txt
  • story-edit-reviewed.txt

Making and commiting changes

• Two ways
• Using git bash
  • About this in command's section.
• Using github
  • Give a demo.

What is a Commit?

• A commit is when you tell Git to save these staged changes.

What is a Pull Request?

• When you open a pull request, you're proposing your changes and requesting that someone review and pull in your contribution and merge them into their branch.

• Pull requests show diffs, or differences, of the content from both branches. The changes, additions, and subtractions are shown in different colors.

Mention username in pull request

`@username`

How to merge a pull request?

• At the bottom of the pull request, click Merge pull request to merge the changes into main.

Forks

• Github forks local copy of a project folder/repository.
