Allows you and your team to work together on the same project.
The project doesn't have to be a program. You can use a version control system to write a book with other people.
Version control create a history of all the changes you want to be saved.
It allows you to revert or go back in time if you happen and undo any mistakes that may have been made.
Centralized version control has one main server that saves the content.
Each user has a fully copy of the history of the project locally and they selectively push updates to the main repository location
A location of files and information about all the previous versions of those files.
git clone copies an existing repository to a local folder.
git clone https://github.com/jquery/jquery.git
git pull pulls down any changes from the source repository into your local repository.
cd jquery
git pull
You use the git add to tell git to track specific files.
#Add a specific file
git add Readme.md
#Add a whole everything
git add .
Staging changes informs git about what is about to be changed
git commit takes all of the staged changes and creates a historical bookmark of what changes were made, who made them, and a message that is a brief description of the changes.
git commit -m "Adding a new page"
#Auto stage modified files
git commit -a -m "Adding another new page"
git push sends the most recent commits to the remote source repository. You must have the latest version of the remote repository for a push to be accepted.
#first time push only
git push -u origin master
git push
A merge occurs whenever there are new commits in the source repository and you have commits that have not yet been pushed to the source repository.
Merges happen behind the scenes and are frequently not noticed unless changes conflict with each other.
Merge conflicts occur when changes are made to the same file and git cannot determine which changes should be used.
A fork of a repository is a user's personal copy of another user's repository. The user can make changes as they want and continue to pull updates from the source repository.
A request to take the changes from your repository to be merged into the source repository.
