Make Claude Code your everyday coding partner! Set up your environment and then walk through real-world projects, from building a new app to updating legacy code with tests, refactoring, and security reviews. See what works, and perhaps more importantly, what doesn’t. You’ll learn to control what Claude Code can do with permissions, capture project knowledge in CLAUDE.md and skills, and extend the tool with MCP servers, hooks, and plugins. Less typing, more deciding: Welcome to the new way of coding!

• Plan, write, test, and maintain code with Claude Code
• Work with permissions, CLAUDE.md, skills, MCP servers, hooks, and plugins
• Run subagents, automate Git workflows, administer servers, and more

In this book, you'll learn about:

1. Daily Workflows

   Install Claude Code Windows, macOS, or Linux and write your first prompts. Then learn the habits that ensure your work with Claude Code passes muster: plan before you code, record decisions in CLAUDE.md, and test each output instead of trusting that a task has been completed.

2. Configuration and Extensions

   Decide how much freedom Claude Code gets using permissions and auto mode. Organize project knowledge with rule files, auto memory, and skills, and connect external tools via MCP servers and plugins.

3. Administration

   Speed up your work with subagents, worktrees, background sessions, and more. Use Claude Code to administer Linux servers and secure backups, and explore OpenRouter and local models as alternatives to an Anthropic subscription.
