How yasmngoncalves/git-github-tutorial works
1. Repository type
- This is not an application codebase; it is a single-document tutorial repository.
- The whole repo consists of one content file: README.md.
2. Primary purpose
- The repository teaches beginners how to use Git and GitHub.
- It focuses on the end-to-end workflow of creating a local project, versioning it, and publishing it to GitHub.
3. Main “subsystems”
- Conceptual explanation layer: defines Git vs. GitHub.
- Setup layer: prerequisites like Git installation, GitHub account, and an editor/terminal.
- Local repository workflow: git config, git init, git add, git commit.
- Remote repository workflow: creating a GitHub repo, linking a remote, and pushing.
- Authentication layer: token-based access instead of password login.
- Next-steps learning layer: branches, pull requests, revert, collaboration, GitHub Pages.
4. Data flow / user journey
- The user starts with a local folder and a simple project.
- Git initializes version history locally.
- Changes are staged and committed into the local Git history.
- A new remote repository is created on GitHub.
- The local repository is connected to that remote using origin.
- The commit history is pushed to GitHub, making the project available online.
5. Boundary between local and remote
- The key architectural boundary is local machine vs. GitHub cloud.
- Local operations happen through the terminal in VS Code or another shell.
- Remote operations happen through GitHub’s web interface and Git transport over HTTPS.
6. External dependencies
- Git CLI is the main tool executing version-control commands.
- GitHub is the external hosting and collaboration platform.
- VS Code is optional, serving mainly as the terminal/editor environment.
- A GitHub access token is required for authentication during push.
7. Security/authentication detail
- The tutorial explicitly notes that GitHub no longer accepts account passwords for Git push over HTTPS.
- The token is the credential boundary between the local Git client and GitHub.
- This is important for the diagram because authentication is part of the publish workflow, not a separate application feature.
8. What is not present
- There is no build system, package manager, source code module tree, database, API server, or frontend/backend split.
- There are no runtime services inside the repo itself.
- The repo is purely instructional content.
9. Architecture of the content itself
- The README is organized as a linear learning path:
- concept introduction
- prerequisites
- local Git setup
- first commit
- GitHub repo creation
- remote linking
- push and authentication
- next learning topics
- This makes the document behave like a guided pipeline rather than a feature set.
10. Useful diagram framing
- If drawing an architecture diagram for this repo, represent:
- User
- Local machine / terminal
- Git CLI
- Local repository
- GitHub web UI
- GitHub remote repository
- Token-based authentication
- The main arrows are: user actions → local Git commands → remote GitHub publish.
11. Operational emphasis
- The tutorial’s “critical path” is the publish flow from a local commit to a remote push.
- Everything else supports that flow: installation, setup, repository creation, and authentication.
12. Overall architectural summary
- This repo is a single-page instructional workflow that bridges local version control and remote hosting.
- Its architecture is best understood as a sequence of user actions across two systems: the local Git environment and GitHub.

README.md - Prerequisites · Covers Git installation, GitHub account, and editor/terminal needs
README.md - Next topics · Branches, pull requests, revert, collaboration, and GitHub Pages
README.md
Local Machine
User-side Git workflow and terminal environment
- Terminal · Environment used to run Git commands locally
- VS Code · Optional editor and integrated terminal for the workflow
- Git CLI · Executes config, init, add, commit, and push commands
- Local repo · Version history stored on the user machine
- Local workflow · Configuration, initialization, staging, and committing
- Access token · Token-based HTTPS credential used instead of a password
GitHub
Cloud hosting, remote repository, and collaboration surface
- GitHub UI · Used to create the remote repository on GitHub
- Remote repo · GitHub repository that receives the pushed commit history
- Publish flow · Creates the remote, connects origin, and pushes commits
Other components
- User · Begins with a local folder and follows the tutorial steps
