초급 코드 지구

Git과 GitHub

코드를 저장하고, 브랜치를 나누고, 병합하고, 함께 작업하세요.

Git keeps every version of your work, lets you try ideas without fear, and lets a whole team build one project together. GitHub is where those teams review and ship their code. This track starts with your very first commit and ends with the workflow professional teams follow every day: a branch for each change, a pull request, a code review, green CI checks on a protected main branch, and an automatic deploy right after the merge.

Along the way you will read history like a detective, resolve conflicts calmly, undo mistakes without losing work, and learn exactly which commands rewrite history and when that is dangerous.
