I'm rying to understand how github works

• GitHub Guide
  • HelloWorld steps
  • Markdown syntaxe
  • Git handbook (very useful)

Example 1: Contribute to an existing repository

1. download a repository on GitHub.com to our machine git clone https://github.com/me/repo.git

2. change into the repo directory cd repo

3. create a new branch to store any new changes git branch my-branch

4. switch to that branch (line of development) git checkout my-branch

5. make changes, for example, edit file1.md and file2.md using the text editor

6. stage the changed files git add file1.md file2.md

7. take a snapshot of the staging area (anything that's been added) git commit -m "my snapshot"

8. push changes to github git push --set-upstream origin my-branch

Example 2: Start a new repository and publish it to GitHub

1. create a new directory, and initialize it with git-specific functions git init my-repo

2. change into the my-repo directory cd my-repo

3. create the first file in the project touch README.md

4. git isn't aware of the file, stage it git add README.md

5. take a snapshot of the staging area git commit -m "add README to initial commit"

6. push changes to github git push --set-upstream origin master

Example3: contribute to an existing branch on GitHub

1. assumption: a project called repo already exists on the machine, and a new branch has been pushed to GitHub.com since the last time changes were made locally

2. change into the repo directory cd repo

3. update all remote tracking branches, and the currently checked out branch git pull

4. change into the existing branch called feature-a git checkout feature-a

5. make changes, for example, edit file1.md using the text editor

6. stage the changed file git add file1.md

7. take a snapshot of the staging area git commit -m "edit file1"

8. push changes to github git push
