📄 English Summary
Claude Code for beginners: what it is, how to set it up, and why people won’t shut up about it
Claude Code is an AI coding agent developed by Anthropic that operates in your terminal, reads your entire project, edits files, and loops until the task is completed. It reached a valuation of $1 billion within six months, partly due to non-technical users employing it for SEO, file organization, marketing automation, and even monitoring tomato plants. The setup process takes under ten minutes: install, authenticate, and run 'claude' in your project folder. The most crucial setup file is CLAUDE.md, which gives Claude permanent memory about your codebase. Plan Mode allows Claude to think and propose a plan before making any changes, which is essential for tasks that span multiple files. Claude Skills are installable and reusable workflows, with over 25,000 available on GitHub.
