What is Github?
GitHub is a code hosting platform using the Git version control system. It lets you and others work together on projects from anywhere
Connect Git with Github
We need to authenticate with GitHub using either HTTPS or SSH (Secure Shell Protocol). Since SSH is more secure, this is the recommended path.
- Generate an SSH key and add it to the ssh-agent
- Add your SSH key to your GitHub account
- Test your SSH connection
Create a repository on Github
Will be two ways to create a new repository:
Connect local and push the changes on Github
Clone a repository
git clone git@github.com:pazteddy/patrones_diseno_java.gitMore than 90% of software projects in the world use Git.
Almost every job description for software developers mentions Git as a requirement.
