Claude Code Tutorial 2026: Complete Setup & Usage Guide
Step-by-step guide to Claude Code: installation, configuration, best prompts for coding, and real-world usage tips. Works with Claude Opus 4.6 and Sonnet 4.5.
Claude Code Tutorial 2026: From Installation to Advanced Workflows
Claude Code is Anthropic's terminal-based AI coding agent. Unlike IDE extensions that bolt AI onto your editor, Claude Code lives in your terminal and operates directly on your codebase with full filesystem access. It reads files, writes code, runs commands, manages Git workflows, and even creates pull requests -- all from a single conversational interface.
This guide takes you from zero to productive with Claude Code. Whether you are setting it up for the first time or looking to unlock advanced features like hooks and sub-agents, every section includes real commands and practical examples you can follow along with.
What Is Claude Code (And What It Is Not)
Claude Code is not an IDE plugin. It is not a VS Code extension, not a tab-completion engine, and not a chatbot sidebar. It is an agentic coding tool that runs in your terminal and has direct access to your project files, shell environment, and Git history.
Here is what makes it different:
- Full filesystem access. Claude Code can read, write, and edit any file in your project. It does not need you to copy-paste code into a chat window.
- Shell execution. It runs terminal commands -- installing dependencies, running tests, executing build scripts -- and reads the output to inform its next steps.
- Git-native. It understands your repository's history, branches, and diffs. It can stage changes, write commit messages, create branches, and open pull requests.
- Agentic behavior. Give it a high-level task ("refactor the authentication module to use JWT") and it plans, executes, and iterates autonomously across multiple files.
- Context-aware. Through CLAUDE.md files, it learns your project's conventions, architecture, and preferences -- and remembers them across sessions.
Think of Claude Code as a senior developer sitting in your terminal, pair-programming with you through natural language.
How Claude Code Differs from Chat-Based AI
When you use Claude on claude.ai or the API, you send a prompt and get a response. Claude Code goes further: it operates in a loop. It reads your codebase, makes a plan, executes changes, observes the results (including error output), and iterates until the task is done. This agentic loop is what separates it from traditional AI chat.
Installation
Claude Code requires Node.js 18 or later. If you do not have Node.js installed, grab it from nodejs.org or use a version manager like nvm.
Step 1: Install Claude Code globally
npm install -g @anthropic-ai/claude-code
Verify the installation:
claude --version
You should see output like claude-code v1.x.x.
Step 2: Authenticate
Navigate to any project directory and launch Claude Code:
cd ~/my-project
claude
On first launch, Claude Code will open a browser window for authentication. You have two options:
- Anthropic account (recommended). Sign in with your Anthropic Console account. Usage is billed to your API account at standard Claude API rates.
- Claude Max subscription. If you have a Claude Max plan ($100/month or $200/month), you can connect it for included Claude Code usage with higher rate limits.
After authenticating, the Claude Code REPL will start and you will see the > prompt. You are ready to go.
Step 3: Verify your setup
Run the built-in diagnostic:
> /doctor
This checks your Node.js version, authentication status, Git configuration, and network connectivity. Fix any issues it reports before continuing.
Updating Claude Code
Claude Code updates frequently. To get the latest version:
npm update -g @anthropic-ai/claude-code
Or let Claude Code update itself:
> /update
Your First Commands
Once inside the Claude Code REPL, these commands will orient you.
Getting help
> /help
This prints all available slash commands with brief descriptions. It is your cheat sheet while learning.
Checking your model
> /model
This shows which Claude model is currently active. By default, Claude Code uses Claude Sonnet 4 for its balance of speed and capability. You can switch to Opus 4.6 for harder tasks:
> /model claude-opus-4-6
Note that Opus 4.6 is significantly more expensive per token ($5/$25 vs Sonnet's $3/$15), so use it strategically for complex architectural decisions, large refactors, or when Sonnet is not producing satisfactory results. Opus 4.6 also supports a 1M token context window (beta) and Agent Teams.
Checking costs
> /cost
This shows your token usage and estimated cost for the current session. Get in the habit of checking this periodically.
Clearing context
> /clear
When your conversation gets long and Claude Code starts losing track of earlier context, clear the slate. Your files on disk are unaffected -- only the conversation memory resets.
Your First Task: A Practical Walkthrough
Let us walk through a realistic task. Suppose you have a utility function that is getting unwieldy:
// utils/format.ts
export function formatUserData(user: any) {
let result = '';
if (user.firstName && user.lastName) {
result = user.firstName + ' ' + user.lastName;
} else if (user.firstName) {
result = user.firstName;
} else if (user.email) {
result = user.email;
} else {
result = 'Anonymous';
}
if (user.role === 'admin') {
result = '[ADMIN] ' + result;
}
if (user.role === 'moderator') {
result = '[MOD] ' + result;
}
if (user.isVerified) {
result = result + ' ✓';
}
return result;
}
Give Claude Code the task
> Refactor the formatUserData function in utils/format.ts. Break it into
smaller functions, add proper TypeScript types, and add JSDoc comments.
Keep the same external behavior.
What happens next
Claude Code will:
- Read
utils/format.tsto understand the current implementation. - Plan a refactoring strategy (you will see it thinking through the approach).
- Write the refactored code with proper types and documentation.
- Show you the diff and ask for confirmation before saving.
The result might look like:
// utils/format.ts
/** Represents a user with optional profile fields. */
interface User {
firstName?: string;
lastName?: string;
email?: string;
role?: 'admin' | 'moderator' | 'user';
isVerified?: boolean;
}
/** Maps user roles to their display prefix. */
const ROLE_PREFIXES: Record<string, string> = {
admin: '[ADMIN]',
moderator: '[MOD]',
};
/**
* Resolves the display name from available user fields.
* Priority: full name > first name > email > "Anonymous"
*/
function resolveDisplayName(user: User): string {
if (user.firstName && user.lastName) {
return `${user.firstName} ${user.lastName}`;
}
return user.firstName ?? user.email ?? 'Anonymous';
}
/** Returns the role prefix if applicable, or empty string. */
function getRolePrefix(role?: string): string {
if (!role) return '';
return ROLE_PREFIXES[role] ?? '';
}
/**
* Formats user data into a human-readable display string.
*
* @example
* formatUserData({ firstName: 'Jane', role: 'admin', isVerified: true })
* // => '[ADMIN] Jane ✓'
*/
export function formatUserData(user: User): string {
const name = resolveDisplayName(user);
const prefix = getRolePrefix(user.role);
const verified = user.isVerified ? ' ✓' : '';
return `${prefix ? prefix + ' ' : ''}${name}${verified}`;
}
Accepting or rejecting changes
Claude Code always shows you what it plans to change. You can:
- Accept the changes (press Enter or type "yes").
- Request modifications ("Make the role type a string enum instead of a union type").
- Reject ("No, keep the original approach but just add types").
This back-and-forth is the core workflow. Claude Code proposes, you decide.
CLAUDE.md: Your Project's Memory
CLAUDE.md is the most important feature you are probably not using yet. It is a Markdown file that tells Claude Code how your project works, what conventions to follow, and what to avoid. Claude Code reads it automatically at the start of every session.
Where to put CLAUDE.md files
Claude Code looks for CLAUDE.md in multiple locations, merged in this order:
| Location | Scope | Use case |
|---|---|---|
~/.claude/CLAUDE.md |
Global (all projects) | Personal preferences, global rules |
./CLAUDE.md |
Project root | Project architecture, conventions, commands |
./src/CLAUDE.md |
Subdirectory | Module-specific instructions |
What to put in CLAUDE.md
Here is a practical CLAUDE.md for a Next.js project:
# CLAUDE.md
## Project Overview
E-commerce platform built with Next.js 15 App Router, TypeScript,
Tailwind CSS, and Drizzle ORM. PostgreSQL database.
## Development Commands
- `npm run dev` - Development server on port 3000
- `npm run build` - Production build
- `npm run test` - Run Vitest test suite
- `npm run db:migrate` - Run database migrations
## Architecture
- app/ - Next.js App Router pages and layouts
- components/ - Reusable React components (use Shadcn/UI)
- lib/ - Utility functions and shared logic
- server/ - Server-side code (API routes, database queries)
- drizzle/ - Database schema and migrations
## Conventions
- Use named exports, not default exports
- All components use TypeScript interfaces (not `type` aliases)
- CSS: Tailwind only, no CSS modules
- Tests: Co-locate test files next to source (*.test.ts)
- Commits: Use conventional commits (feat:, fix:, refactor:)
- Never use `any` type. Use `unknown` and narrow with type guards.
## Important Context
- Auth: NextAuth.js v5 with database sessions
- Payments: Stripe integration in server/stripe/
- The /api/webhooks/stripe route must NOT have auth middleware
Why CLAUDE.md matters
Without CLAUDE.md, Claude Code makes reasonable guesses about your project. With it, Claude Code follows your exact conventions from the first prompt. The difference is dramatic:
- Without: Claude Code might generate CSS modules when you use Tailwind, or default exports when you use named exports.
- With: Every generated file matches your existing patterns from the start.
Adding to CLAUDE.md from inside Claude Code
You can update your CLAUDE.md without leaving the session:
> /add-memory Always use `pnpm` instead of `npm` in this project
This appends the instruction to your project's CLAUDE.md file.
Key Slash Commands Reference
Here is a complete reference of the slash commands you will use most often:
| Command | What it does |
|---|---|
/help |
Show all available commands |
/model |
View or switch the active Claude model |
/cost |
Display token usage and cost for current session |
/clear |
Reset conversation context (files on disk are unaffected) |
/compact |
Compress conversation history to save context window space |
/doctor |
Run diagnostics (Node.js, auth, Git, network) |
/add-memory |
Append an instruction to your CLAUDE.md |
/review |
Review code changes (like a PR review) |
/update |
Update Claude Code to the latest version |
/config |
View or modify configuration settings |
/logout |
Sign out of your Anthropic account |
/vim |
Toggle vim-style keybindings in the REPL |
The /compact command deserves special attention
As your conversation grows, Claude Code's context window fills up. When you notice responses becoming less accurate or Claude Code "forgetting" earlier context, run:
> /compact
This summarizes the conversation so far into a compressed form, freeing up context window space while preserving the key information. It is like taking notes and starting a fresh page -- you keep the knowledge but reclaim the space.
A good rule of thumb: run /compact every 20-30 exchanges, or whenever Claude Code starts making mistakes about things you already discussed.
Working with Git
Git integration is one of Claude Code's strongest features. It understands repositories deeply and can handle everything from simple commits to complex PR workflows.
Smart commit messages
After making changes, ask Claude Code to commit:
> Commit the changes we just made with a descriptive message
Claude Code will:
- Run
git diffto see all changes. - Analyze the nature of the changes (bug fix, feature, refactor).
- Write a conventional commit message.
- Stage the relevant files (not blindly
git add .). - Create the commit.
Example output:
git add src/utils/format.ts src/utils/format.test.ts
git commit -m "refactor: extract helper functions from formatUserData
- Add User interface with proper TypeScript types
- Extract resolveDisplayName() and getRolePrefix() helpers
- Add JSDoc documentation with usage examples
- Maintain backward-compatible external API"
PR creation
Claude Code can create entire pull requests:
> Create a PR for the current branch. Summarize all changes since we
branched from main.
It will:
- Analyze all commits on the branch using
git log. - Read the diffs to understand the full scope of changes.
- Generate a PR title and description.
- Push the branch and create the PR using
gh pr create.
PR review
You can also use Claude Code to review pull requests:
> Review PR #42. Focus on security issues and performance.
Claude Code will fetch the PR diff, analyze the changes, and provide structured feedback -- similar to what a senior engineer would catch in code review.
Resolving merge conflicts
> We have merge conflicts after rebasing on main. Resolve them,
keeping our feature changes but adopting main's API updates.
Claude Code will read the conflict markers, understand the intent of both sides, and resolve them intelligently.
Cost Management Tips
Claude Code bills per token through the Anthropic API. Here is how to keep costs predictable.
Typical monthly costs
Based on community reports and typical usage patterns:
| Usage level | Monthly cost | Profile |
|---|---|---|
| Light | $5-15 | Occasional refactors, quick questions, small fixes |
| Moderate | $20-50 | Daily development, PR reviews, regular coding sessions |
| Heavy | $50-150 | Full-time pair programming, large refactors, multi-file tasks |
Strategies to reduce costs
1. Use Sonnet for most tasks. Claude Sonnet 4 handles 90% of coding tasks well. Reserve Opus 4.6 for genuinely hard problems.
> /model claude-sonnet-4 # Default, cost-effective
> /model claude-opus-4-6 # More expensive, use sparingly
2. Use /compact regularly. Long conversations consume more tokens on every exchange because the entire history is sent with each message. Compacting reduces this overhead significantly.
3. Be specific in your prompts. Instead of "improve this file," say "add error handling to the fetchUser function for network timeouts and 404 responses." Specific prompts lead to fewer back-and-forth iterations.
4. Use /clear between unrelated tasks. If you finish a refactoring task and move on to writing tests for a different module, clear the context. Carrying irrelevant context wastes tokens.
5. Point Claude Code to the right files. Instead of "find the bug in the auth system," say "there's a bug in lib/auth/session.ts where expired tokens aren't being refreshed." Less searching means fewer tokens.
6. Use Claude Max for heavy usage. If you consistently spend more than $100/month on API usage, the Claude Max plan ($100 or $200/month) may offer better value with its included Claude Code usage and higher rate limits.
Monitoring costs in real time
> /cost
Run this periodically. If a single session exceeds $2-3, consider whether you are being efficient or if the task should be broken into smaller pieces.
Claude Code vs Cursor vs GitHub Copilot
Here is how Claude Code compares to the other major AI coding tools in 2026:
| Feature | Claude Code | Cursor | GitHub Copilot |
|---|---|---|---|
| Interface | Terminal (CLI) | VS Code fork (IDE) | IDE extension |
| Interaction model | Conversational agent | Chat + inline edit | Autocomplete + chat |
| Filesystem access | Full (reads/writes files directly) | Full (within IDE) | Limited (current file focus) |
| Shell execution | Yes (runs commands, reads output) | Yes (terminal integration) | Limited |
| Git integration | Deep (commits, PRs, reviews) | Basic (through IDE) | Deep (GitHub ecosystem) |
| Multi-file edits | Excellent (agentic planning) | Good (with Composer) | Improving |
| Context window | 200K tokens | Varies by model | 128K tokens |
| Model choice | Claude Sonnet 4 / Opus 4.6 | Claude, GPT, Gemini | GPT-4o, o3 |
| Pricing | Pay-per-token (~$20-50/mo) | $20/mo (Pro) | $10/mo (Individual) |
| Best for | Terminal-native devs, agentic tasks | Visual editing, frontend work | Quick completions, GitHub-heavy teams |
| Headless/CI use | Yes (runs without UI) | No | Limited (CLI exists) |
When to choose Claude Code
- You live in the terminal and prefer keyboard-driven workflows.
- You need agentic capabilities: multi-file refactors, automated PR creation, test generation across a codebase.
- You want to run AI coding in CI/CD pipelines or on remote servers.
- You work on backend systems, infrastructure, or CLI tools where a GUI IDE adds little value.
When to choose Cursor
- You prefer a visual IDE with inline diffs and a polished UI.
- You do significant frontend work where seeing the result matters.
- You want to switch between different AI models (Claude, GPT, Gemini) based on the task.
- You value the Composer feature for multi-file edits with visual preview.
When to choose GitHub Copilot
- You want the lowest-cost entry point at $10/month.
- You are deeply embedded in the GitHub ecosystem (Issues, PRs, Actions).
- You primarily need autocomplete-style assistance rather than agentic behavior.
- Your team has standardized on Copilot and consistency matters.
Combining tools
Many developers use Claude Code alongside an IDE tool. A common setup:
- Cursor for visual editing, frontend work, and quick inline fixes.
- Claude Code for large refactors, Git workflows, code reviews, and tasks that span many files.
They complement each other well because they operate in different environments.
Advanced: Hooks, Sub-Agents, and Director Mode
Once you are comfortable with the basics, these advanced features will take your productivity further.
Hooks: Automating repetitive actions
Hooks let you run custom scripts automatically when certain events happen in Claude Code. They are configured in your project's .claude/settings.json file.
{
"hooks": {
"on_tool_start": [
{
"matcher": "write",
"command": "echo 'File being written: $CLAUDE_FILE_PATH'"
}
],
"on_tool_end": [
{
"matcher": "write",
"command": "npx prettier --write $CLAUDE_FILE_PATH"
}
],
"on_message": [
{
"command": "date >> ~/.claude/activity.log"
}
]
}
}
In this example:
- on_tool_start (write): Logs every file write to the console.
- on_tool_end (write): Automatically runs Prettier on every file Claude Code writes or edits, ensuring consistent formatting without having to ask.
- on_message: Logs a timestamp for every Claude Code interaction to an activity file.
Common hook use cases:
- Auto-format code after every edit (Prettier, Black, gofmt).
- Run linting on changed files.
- Auto-run tests related to modified files.
- Log all file modifications for audit purposes.
- Send notifications to Slack when certain files are changed.
Sub-Agents: Delegating specialized tasks
Claude Code can spawn sub-agents -- smaller, focused Claude instances that handle specific subtasks. This happens automatically when Claude Code breaks a large task into pieces, but you can also guide it:
> Refactor the entire authentication module. For each file you change,
also generate corresponding unit tests.
Claude Code may use its internal Task tool to spin up focused sub-agents: one for the refactoring plan, one for each file's changes, and one for test generation. Each sub-agent gets a focused context window, which improves accuracy on complex tasks.
You do not need to manage sub-agents directly. Just give Claude Code ambitious, multi-step tasks and it will decide when to delegate internally.
Director Mode: Multi-agent orchestration
For very large tasks, you can run Claude Code in a director-like pattern by using multiple terminal sessions:
Terminal 1 (Director):
> I need to migrate our REST API to GraphQL. Let's start with the
user module. Plan the migration and tell me what files need to change.
Terminal 2 (Worker):
> Convert server/routes/users.ts from REST to a GraphQL resolver.
Follow the schema defined in schema/user.graphql.
Terminal 3 (Worker):
> Update all frontend components in components/user/ to use GraphQL
queries instead of REST fetch calls. Use the @apollo/client hooks.
By running multiple Claude Code instances targeting different parts of the codebase, you can parallelize large migrations. The Director terminal plans and coordinates while Worker terminals execute specific pieces.
Headless Mode for CI/CD
Claude Code can run non-interactively, which makes it useful in CI/CD pipelines:
# Run a single task and exit
claude -p "Review the changes in this PR and output a summary" \
--output-format json
# Pipe input
echo "Add error handling to all database queries in server/db/" | \
claude -p --allowedTools "Read,Write,Edit"
Practical CI/CD use cases:
- Automated PR reviews: Run Claude Code on every PR to generate review comments.
- Documentation generation: Auto-generate or update API documentation after endpoint changes.
- Test generation: Create tests for new files that lack coverage.
- Commit message validation: Ensure commit messages follow conventional commit format.
Example GitHub Actions workflow:
name: Claude Code PR Review
on:
pull_request:
types: [opened, synchronize]
jobs:
review:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: '22'
- run: npm install -g @anthropic-ai/claude-code
- run: |
claude -p "Review the changes in this PR. Focus on bugs,
security issues, and performance problems. Output as markdown." \
--output-format text > review.md
env:
ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
- name: Post review comment
uses: actions/github-script@v7
with:

body: review
});
10 Best Practices from Experienced Claude Code Developers
These tips come from developers who have been using Claude Code daily for months.
1. Start every project with a CLAUDE.md
Before writing a single line of code with Claude Code, spend 10 minutes writing a CLAUDE.md. Document your tech stack, conventions, and commands. This one-time investment pays off on every single interaction.
2. Be explicit about what NOT to do
Claude Code responds well to negative constraints. Include rules like:
## Rules
- Never use `any` type in TypeScript
- Never install new dependencies without asking first
- Never modify files in the migrations/ directory
- Never commit directly to main
3. Use /compact before it is too late
Do not wait until Claude Code starts hallucinating or forgetting context. Proactively compact every 20-30 exchanges. Think of it like saving your game -- do it regularly, not just when things go wrong.
4. Break large tasks into phases
Instead of "build me a user management system," try:
> Phase 1: Create the database schema for users with email,
password hash, role, and timestamps. Use Drizzle ORM.
> Phase 2: Create the CRUD API routes for users. Include validation
with Zod schemas.
> Phase 3: Add authentication middleware using JWT. Include refresh
token rotation.
Each phase gets focused attention and you can review and adjust between phases.
5. Always review diffs before accepting
Claude Code shows you what it plans to change. Read the diffs. Do not blindly accept multi-file changes. This is your codebase and you are responsible for what goes in. Treat Claude Code's output like a PR from a junior developer -- usually good, occasionally needs correction.
6. Use Claude Code for code review
One of the most underused features. After finishing a feature:
> Review all the changes we've made in this session. Look for bugs,
edge cases, security issues, and inconsistencies with the rest of
the codebase.
Claude Code will read through all modifications and often catches issues you missed.
7. Leverage the terminal for verification
After Claude Code makes changes, verify them:
> Run the tests to make sure nothing is broken
> Try building the project to check for type errors
Claude Code will execute the commands and react to any failures, fixing issues iteratively until things pass.
8. Use Git branches for experimental tasks
Before asking Claude Code to do something risky:
> Create a new branch called 'experiment/new-auth-flow' and switch to it
Now you can let Claude Code experiment freely. If the result is not what you want, just switch back to your original branch.
9. Teach Claude Code through examples
Instead of describing what you want abstractly, show an example:
> Look at how we implemented the UserService in server/services/user.ts.
Now create a similar ProductService following the same patterns,
including the error handling approach and the repository abstraction.
Pattern-based instructions produce more consistent results than abstract descriptions.
10. Combine Claude Code with your existing tools
Claude Code does not replace your entire toolkit. Use it alongside:
- Your test suite -- ask Claude Code to run tests after every change.
- Your linter -- configure hooks to auto-lint.
- Your CI pipeline -- push and let CI catch what local testing missed.
- Your IDE -- review Claude Code's changes visually in VS Code or Cursor.
The best results come from treating Claude Code as one powerful tool in your workflow, not a replacement for everything.
Troubleshooting Common Issues
"Permission denied" during installation
# Fix npm global permissions
mkdir -p ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH=~/.npm-global/bin:$PATH
# Then install again
npm install -g @anthropic-ai/claude-code
Add the PATH export to your ~/.bashrc or ~/.zshrc to make it permanent.
Claude Code is slow or timing out
- Check your internet connection.
- Run
/doctorto identify issues. - If using Opus 4.6, switch to Sonnet 4 for faster responses.
- Large files (>1000 lines) can slow down processing. Point Claude Code to specific functions rather than entire files.
Claude Code is not reading my files
Make sure you launched Claude Code from your project directory:
cd ~/my-project
claude
Claude Code uses the current working directory as its root. If you start it from ~, it will not automatically find your project files.
Changes are not what I expected
- Add more detail to your CLAUDE.md.
- Be more specific in your prompts.
- Show Claude Code an example of what you want.
- Use
/clearand start fresh with a more precise description.
What Is Coming Next for Claude Code
Anthropic is actively developing Claude Code with frequent updates. Based on the current trajectory and community discussions, here is what to watch for in 2026:
- Improved memory across sessions. Better persistence of project understanding between sessions, reducing the need to re-explain context.
- Native IDE integration. While Claude Code is terminal-first, Anthropic has hinted at tighter IDE integrations that preserve the agentic model.
- Claude Fable 5 integration. Claude 5 has launched as Claude Fable 5. Watch for Claude Code workflows that route the hardest long-horizon coding tasks to
claude-fable-5. - Expanded MCP tooling. The Model Context Protocol (MCP) allows Claude Code to interact with external tools like databases, APIs, and cloud services. Expect the ecosystem of MCP servers to grow rapidly.
