A repository without a README is a closed door. Visitors arrive, see a list of files with cryptic names, and leave. The README is the first thing GitHub renders on the repository home page, and it is the single artifact that determines whether a stranger becomes a user, a contributor, or a bounce. This chapter…
The command line is the foundation of Git, but it isn’t the only way to use it. Git GUIs, IDE integrations, aliases, and hooks turn Git from a tool you type into a tool that works with you — showing history visually, catching mistakes before they happen, automating the repetitive parts. Key point: The command…
A local Git repository is an island. Commits accumulate in the .git directory, branches are created and merged, but none of it is visible to anyone else until the repository is connected to a remote. git remote establishes that connection, and git push transmits the commits across it. For a new project, this is a…
A single-page reference for the Git commands you’ll reach for most. Grouped by task, with a short description of what each does. Bookmark it — you’ll come back often. Key point: This isn’t a tutorial — it’s a lookup table. When you know what you want but not the exact syntax, find the command here….
Cloning and forking are often confused because both create copies of a repository. But they operate in different places and serve different purposes. A clone is a local copy on your computer, created with git clone. A fork is a server-side copy on your GitHub account, created with the “Fork” button. The distinction matters because…

A repository is more than code. It is a workspace where bugs are reported, features are proposed, and work is tracked. GitHub Issues provides the infrastructure for that work: a flexible item type for discussion and planning . But an unstructured issue tracker becomes noise. Labels categorize issues by type and priority. Milestones group them…

A pull request is the mechanism that turns a private branch into a proposal. It is not a Git operation—Git itself has no concept of a pull request. It is a GitHub feature that wraps a branch in a review workflow: discussion, automated checks, and a merge gate. For a contributor, a pull request is…
A pull request opens a conversation, but a code review is the structured evaluation of the proposed changes. It is not just a place to leave comments; it is a workflow gate that determines whether code enters the main branch. GitHub provides specific tools for this: inline comments on specific lines, suggested changes that can…
