Git and GitHub Tutorial for Beginners

Here is a summary of the text in detailed bullet points:

• The speaker is introducing a tutorial on Git and GitHub for absolute beginners, using a simple project as an example.

• The project is a game called "Snake vs. Blocks" with thousands of lines of code, and the speaker wants to collaborate with a friend on the project.

• The speaker explains that without Git, collaborating on the project would be difficult, as they would have to send the entire codebase to their friend, who would then make changes and send it back.

• The speaker notes that this process would be cumbersome and prone to errors, and that's where Git comes in.

• Git is a version control system that allows multiple people to collaborate on a project by tracking changes and allowing for easy reverting to previous versions.

• The speaker explains that Git adds about 7.5 MB of data to the project, but gives the power to experiment, collaborate, and work more efficiently.

• Without Git, the speaker would have to make copies of the code at every point, resulting in a large amount of data (e.g. 2 GB for 150 copies).

• Git instead distills the differences between versions, making it more efficient.

• The speaker introduces GitHub, a platform that allows users to host their repositories (projects) remotely and access them from anywhere.

• GitHub provides a graphical interface to view and manage different versions of the project.

• The speaker explains that Git and GitHub are not the same thing, and that Git can be used without GitHub.

• To get started with Git, the speaker recommends installing Git on the local machine and setting up global settings such as name and email.

• The speaker explains that SSH is a way to securely log in to GitHub without a password, but it's optional and can be set up later.

• The speaker walks through the process of creating a new repository, initializing it with Git, and making the first commit.

• The speaker explains that a commit is like a checkpoint in the project's history, and that it's necessary to add files to the stage before making a commit.

• The speaker introduces Git commands such as git status, git add, and git commit, and explains how they work.

• The speaker notes that it's essential to try out the commands for oneself to learn, and not to be afraid of making mistakes.

• The speaker also recommends making a copy of the project sometimes in case mistakes are made and it's necessary to roll back to a previous version.

• The speaker concludes the local usage of Git and prepares to move on to hosting the repository on GitHub.

• GitHub provides an opportunity to create a README file, which is a text file that appears on the main project page.
• To create a new repository, GitHub gives options to create a new repository or push an existing one, with commands provided for each.
• To create a new repository, a README file is created, and the git init command is used to add Git tracking.
• The git add command is used to add files to the stage, and a commit is made with a commit message.
• The git remote add origin command is used to link a local repository to a remote repository, and git push -u origin master is used to upload local commits to the remote repository.
• If using HTTPS, a username and password will be required for authentication.
• The commits section on GitHub shows the commit history, with details of changes made.
• Collaborators can be added to a project by going to settings and adding their username.
• The git pull command is used to take changes from the remote repository and add them to the local repository.
• The git clone command is used to create a copy of a project, and can be used to create a new copy of a public repository.
• GitHub can be used for versioning websites and blogs, with tracking and source code available online.
• Additional resources for learning Git include GitHub Student Pack, cheat sheets, and books such as "Pro Git" by the founder.
• A .gitignore file is used to tell Git to ignore certain files, such as Python .pyc files.
