Claude Code Basics
In Claude Code, you can streamline everyday coding tasks with a few core concepts:
- Projects & Context: Open a project folder so Claude can read the files you reference and provide grounded assistance.
- Chats: Use chats to ask questions, generate or refactor code, and review suggested changes before applying them.
- Models: Choose an available Claude model that fits your task. Higher‑capability models help with complex refactors; lighter models respond faster for quick iterations.
- MCP Tools: Connect external tools and data sources via MCP for richer, task‑specific context.
- CLI: Use the integrated terminal to run the Claude Code CLI for scripted flows and automation.
Explore Claude Code CLI Reference to learn available commands, and refer to product docs for current model options and guidance.
