Developer Tooling

Developer tooling is a top-level branch for tools you use every day to write and ship code. The first posts teach the mental model of the tool itself, not a release pipeline. That is why this branch sits beside Computer Science Fundamentals rather than under DevOps. Git is the first leaf. Later leaves can hold editors, debuggers, and package managers when those notes exist. Read this branch when a command you type every day still feels like magic.
