How to Use Cursor: Complete Tutorial for Beginners (2026)

Cursor is an AI-native code editor built on VS Code that provides Tab completions, Composer for multi-file edits, and Agent mode for autonomous task execution. This beginner tutorial walks you through installation, core workflows, custom rules, model selection, and practical tips for getting the most out of the AI-first IDE.

TL;DR

• Download Cursor from cursor.com, open a project folder, and use Tab for inline completions and Ctrl+I / Cmd+I for Composer.
• Composer turns plain-language descriptions into multi-file diffs you review before applying; nothing changes until you approve.
• Agent mode extends Composer with terminal commands and test execution, requiring explicit approval for each step.
• Use .cursorrules to set project-specific conventions (style, testing, stack) so AI output matches your codebase.
• Cursor supports 25+ models; the Hobby tier is free with a two-week Pro trial, and Pro starts at $20/month.

Quick Answer

Download from cursor.com, open a project folder, and start with a simple Composer prompt like "Add a loading state to this component."

Step 1: Install and Set Up

1. Go to cursor.com and download Cursor for your OS.
2. Install and launch.
3. Sign up or log in.
4. Open a project folder (File > Open Folder).

Cursor uses the same keybindings and extension system as VS Code, so most of your workflow carries over.

Step 2: Tab Completions

• What it does: Suggests the next lines of code as you type (gray "ghost" text).
• Accept: Tab
• Dismiss: Esc
• Cycle options: Alt+] / Alt+[ (Windows/Linux) or Option+] / Option+[ (Mac)

Completions use your file and project context. Writing a clear comment often improves suggestions: e.g., // Fetch user from API and cache for 5 minutes.

Step 3: Composer (Multi-File Edits)

Composer turns natural-language descriptions into multi-file code changes.

Open Composer: Ctrl+I (Windows/Linux) or Cmd+I (Mac)

Good prompt example:

Add a /profile page:
- New route at app/profile/page.tsx
- Fetch user data from /api/user
- Show name, email, and avatar
- Add a nav link in components/Nav.tsx
- Use existing Tailwind styles from the project

Workflow:

1. Type your request in Composer.
2. Review the proposed diffs per file.
3. Accept, reject, or request revisions.
4. Nothing is applied until you approve.

Step 4: Agent Mode

Agent mode lets Cursor run terminal commands, execute tests, and perform multi-step tasks.

• When to use: Debugging, running tests, applying migrations, multi-step refactors.
• Safety: Cursor shows you proposed commands and file changes before executing. Approve or reject each step.
• Toggle: Use the Agent toggle in Composer or the relevant UI when starting a task.

Step 5: Rules and Context

Cursor uses rules to tailor behavior. You can add:

• Project rules — In .cursorrules or project settings.
• Example: "Always use our Button component from components/Button.tsx" or "Use TypeScript strict mode."

Rules help keep Composer and Agent output aligned with your conventions.

Step 6: Model Selection

Cursor supports 25+ models (GPT, Claude, Gemini). On Pro and higher:

• Choose your default model in settings.
• Switch models per chat or Composer session if needed.
• Higher tiers unlock more models and background agents.

Practical Tips

• Be specific in prompts — Include file paths, tech stack, and constraints.
• Work in small steps — One feature or refactor per Composer session.
• Review diffs — Always check changes before accepting, especially on main branches.
• Use rules — Document your conventions so Cursor follows them.
• Run tests after edits — Composer and Agent can introduce bugs; verify with your test suite.

Final Takeaways

1. Cursor = Tab completions + Composer + Agent — Tab for flow, Composer for multi-file edits, Agent for orchestration.
2. Start with Composer for a concrete task; review diffs before applying.
3. Use rules to align output with your project conventions.
