GitHub GH-900: GitHub Foundations

Exam GH-900, GitHub Foundations, is a current beginner certification as of October 1, 2026. The January 2026 objectives cover Git and GitHub basics, repository work, collaboration, modern development practices, project management, privacy and security, administration concepts, and participation in the GitHub community. The exam is designed for developers and non-developers alike, so it focuses on understanding how the platform works rather than deep specialization in one programming language.

GitHub Foundations is most useful when candidates practice the complete collaboration loop. Creating a repository is only the start. Real GitHub work involves branches, commits, pull requests, issues, reviews, permissions, project tracking, releases, and the social conventions that allow multiple people to change shared work safely.

The certification also provides a base for more specialized paths. GH-100 goes deeper into enterprise administration, GH-200 focuses on GitHub Actions, and GH-300 covers GitHub Copilot. Understanding the foundational objects first makes those advanced features easier to place in context.

Git records history locally while GitHub adds shared collaboration services

Git is the version-control system that tracks commits, branches, merges, and repository history. GitHub hosts Git repositories and adds identity, pull requests, issues, projects, automation, security, packages, discussions, and other services around them. Candidates should be able to explain the difference because many beginner mistakes come from treating Git commands and GitHub platform features as the same layer.

Practice the essential Git commands until status, add, commit, branch, switch, merge, pull, fetch, and push have clear meanings. The goal is not command memorization; it is knowing what changes the working tree, local history, and remote repository at each step.

Repositories organize code, history, configuration, and collaboration

A repository contains more than application files. README documentation, licenses, contribution guidance, issue templates, workflow definitions, security policies, and repository settings all shape how others interact with the project. Candidates should know the difference between public and private visibility and understand that access, forks, and community participation can behave differently according to repository and organization policy.

Good repository hygiene makes the project understandable to someone who did not create it. Clear documentation, meaningful commit history, sensible branch strategy, and predictable file organization reduce the amount of explanation required outside the repository. The basic GitHub workflow becomes much easier when every action is connected to a visible project artifact.

Branches allow parallel change without rewriting the stable line of work

A branch creates a movable reference to commits so work can proceed independently. Feature branches make it possible to develop and review a change before it reaches the default branch. Candidates should understand how branches diverge, how merging combines histories, and why conflicts occur when changes cannot be reconciled automatically.

Branch strategy should match team size and release practice. Small teams may use short-lived branches and frequent merges, while larger projects may add release or maintenance branches. Foundations candidates do not need to master every branching model, but they should understand the reason for isolating unfinished work and the value of integrating changes regularly.

Pull requests turn code changes into a reviewable conversation

A pull request presents a proposed change, its diff, checks, discussion, and review history. Candidates should know how reviewers comment, request changes, approve, and use suggested edits. Draft pull requests can communicate work in progress before a change is ready to merge, while branch protections can require reviews or passing checks.

Strong pull requests explain the problem, summarize the approach, identify testing, and keep scope manageable. Review is not only a gate; it is a knowledge-sharing process. A repository with healthy pull-request habits makes future maintenance easier because important decisions remain connected to the code that implemented them.

Issues and discussions support different kinds of collaboration

Issues are useful for work that needs a defined outcome: bugs, tasks, enhancements, or tracked decisions. Labels, milestones, assignees, templates, and links to pull requests can make the work visible. Discussions are better for open-ended questions, community conversation, announcements, or ideas that are not yet actionable project tasks.

Candidates should practice turning a vague request into a useful issue with context, expected behavior, and acceptance criteria. This makes later development more efficient because the problem definition exists before code changes begin. It also shows how GitHub can support non-code collaboration around a shared project.

Projects make work visible across issues and pull requests

GitHub Projects can organize items using fields, views, filters, and automation so teams can see status, priority, ownership, or release targets. A project board should reflect decisions the team actually uses. Adding dozens of fields that no one maintains creates the appearance of process without improving coordination.

Foundations candidates should understand how project views differ from repository structure. A project can coordinate work that spans repositories, while issues and pull requests remain attached to their specific source locations. This separation helps teams plan at one level and execute changes at another.

Modern development practices use automation without hiding responsibility

Continuous integration can run tests, formatting, builds, or scans whenever code changes. GitHub Actions provides the automation mechanism, but GH-900 only requires foundational understanding of what automated workflows contribute to a repository. The deeper workflow-authoring skills belong to GH-200.

The practical point is that automated checks create fast, repeatable feedback. Developers still need to interpret failures and decide whether a check represents a real problem. Understanding this relationship prepares candidates for more advanced CI/CD pipeline concepts.

Permissions and security protect collaboration without eliminating openness

Repository visibility, organization membership, team access, branch protections, and role permissions determine who can read or change content. Public open-source projects may allow anyone to view code while restricting direct write access to maintainers. Private enterprise repositories require a different access model but still benefit from least privilege.

Candidates should know basic security features such as dependency alerts, secret detection concepts, security policies, and responsible disclosure. They should also understand that tokens and credentials must not be committed to repositories. Security is part of normal repository behavior, not something added only to highly sensitive projects.

The GitHub community model depends on contribution etiquette and clear licenses

Open-source participation begins with understanding a project’s README, contribution guide, code of conduct, issue process, and license. A technically correct patch can still be difficult for maintainers to accept if it ignores project conventions or changes more than necessary. Contributors should communicate intent early when a change is substantial.

Licenses define how others may use, modify, and redistribute a project. Foundations candidates do not need to become lawyers, but they should recognize that a public repository without a license does not automatically grant every reuse right. Community health depends on both technical collaboration and explicit expectations.

Create a repository, clone it locally, make branches, commit changes, open issues, submit pull requests, review a change, resolve a merge conflict, organize work in a project, and enable a simple automated check. Use both the command line and the GitHub interface so that concepts remain clear even when the surface changes.

Then explore the wider GitHub platform and identify which foundations lead into administration, Actions, Copilot, and security specialties. The value of GH-900 is not that it proves expert depth; it establishes a common mental model of repositories, collaboration, security, and project work that every later GitHub role can build on.

Use the January 2026 skill areas as the final checklist. For every domain, be able to explain the concept and perform at least one representative action. That balance prevents two common weaknesses: knowing terminology without practical confidence, or knowing a handful of commands without understanding how GitHub organizes collaborative software work.

Releases and tags add another layer to repository history. A tag can identify a specific commit, while a GitHub release can attach notes and downloadable artifacts to a version. Candidates should understand that the default branch continues moving after a release, so reproducibility depends on being able to identify the exact code and assets associated with a published version.

Notifications and subscriptions help users follow relevant activity without watching every event manually. A healthy collaboration setup lets contributors receive updates for issues, pull requests, discussions, or repositories they care about while avoiding so much noise that important changes are ignored. Managing attention is a practical part of working effectively on a shared platform.

Forks are especially important in open-source contribution. A contributor can create a personal copy, make changes in a branch, and propose them back to the upstream project through a pull request. Candidates should understand the distinction between a fork and a branch because they solve different collaboration problems and have different permission boundaries.

Repository insights can also help maintainers understand activity, contributors, traffic, dependencies, and community health. Foundations candidates do not need advanced analytics, but they should know that GitHub exposes information beyond source code itself. Those signals can guide maintenance priorities and reveal whether a project is attracting users or accumulating unresolved work.

Finally, practice recovering from common mistakes. Undo a local change, revert a commit, resolve a conflict, restore a deleted branch reference where possible, and correct a pull request that targets the wrong base. Confidence with recovery reduces the fear of using version control and makes the underlying Git model much easier to understand.

Basic Markdown is also part of everyday GitHub communication. README files, issues, pull requests, discussions, and release notes all use Markdown to structure headings, lists, links, code blocks, and tables. Clear formatting makes technical context easier to review and reduces misunderstanding, especially in open-source projects where contributors may be working asynchronously across time zones.

Search and navigation skills save time as repositories grow. Candidates should practice locating files, commits, issues, pull requests, users, and code references through the web interface. A foundational user should be able to answer “where did this change come from?” or “is this issue already tracked?” without relying on someone else to reconstruct repository history.
