Claude Code for Beginners: Everything You Need to Know
Claude Code is the programming agent created by Anthropic: you tell it in natural language what you want to build, and it reads the project, writes code in multiple files, runs commands, and checks that everything works. For a beginner, it’s similar to a patient colleague who explains your project, helps you fix errors, and shows you what a good solution would look like.
In the guide below, you’ll learn how to access it, what you can use it for, which extensions are worth installing, how much it costs, and how to use it without sabotaging your learning. Prices and features are current at the time of publication; Anthropic updates the product frequently, so check the official page before choosing a subscription.
What is Claude Code
Claude Code is an “agentic” programming tool: it doesn’t stop at suggestions, but works directly on your project. According to the official documentation, it reads code, edits files, runs commands, and connects to the development tools you already use.
The difference from a regular chatbot is quickly apparent:
| Classic AI Chat | Claude Code | |
|---|---|---|
| Project Access | Only sees what you copy in chat | Sees all files in the project folder |
| Changes | You copy the code back to the editor | Edits files directly, in multiple places at once |
| Verification | You run and report errors | Run tests and commands, read errors and fix them |
| Control | Doesn’t touch anything on your computer | You choose how much control you keep: approve each action or let a safety model check them |
Claude Code uses the Claude models (Opus, Sonnet, and Haiku families) and works with any language: JavaScript, TypeScript, Python, PHP, Java, C#, and more. You don’t need to know how to code to get started, but you do need to understand what it does to use it well; we’ll get to that below.
How to Access Claude Code
You need a paid Claude subscription (Pro or higher) or a pay-per-use Anthropic Console account; the Free plan doesn’t include Claude Code. Then you choose where you want to work, because the same engine runs on multiple platforms and keeps the same project settings.
| Where You Work | Suitable For | How to Get Started |
|---|---|---|
| Desktop app (macOS, Windows, Linux beta) | Beginners who don’t want to use a terminal | Download the Claude app, log in, and open the Code tab |
| Terminal (CLI) | Who wants all the features | Run the installation command, then claude in the project folder |
| VS Code sau Cursor | Who already works in an editor | Search for “Claude Code” in Extensions and install it |
| JetBrains (IntelliJ, PyCharm, WebStorm) | Java, Python, web developers | Plugin from JetBrains Marketplace, plus CLI installed separately |
| Web and mobile | Projects on GitHub, long tasks | Go to claude.ai/code or the Claude app for iOS and Android |
Installation in the Terminal, Step by Step
- Open the terminal (Terminal on macOS, PowerShell on Windows).
- Run the installation command for your system (see below).
- Open a new terminal window and verify the installation with claude –version.
- Enter the project folder with cd project-name, then type claude.
- On the first start, you log in with the Claude account, directly from the browser.
On macOS, Linux or WSL:
curl -fsSL https://claude.ai/install.sh | bash
On Windows, in PowerShell:
irm https://claude.ai/install.ps1 | iex
The native variant updates itself in the background. If you prefer a package manager, you can also use brew install –cask claude-code (macOS) or winget install Anthropic.ClaudeCode (Windows), but these do not update automatically. On Windows, the documentation also recommends installing Git for Windows.
Beginner tip: If the terminal seems intimidating, start with the desktop app. It already includes Claude Code, shows you visually what files it has modified, and you can always switch to the terminal later.
What You Can Use Claude Code For
The most useful tasks for a beginner are the ones where Claude Code saves you from getting stuck, not learning: understanding foreign code, fixing bugs, and completing portfolio projects. You can also write the prompt in Romanian.
| What You Are Looking to Achieve | Prompt Example |
|---|---|
| Understand a new project | “Explain the structure of this project and where the authentication is done.” |
| Fix a bug | “I get this error on npm start: [paste message]. Find the cause and explain the solution.” |
| Build a project from scratch | “Create a to-do app in React with localStorage. Come up with a plan first.” |
| Write tests | “Write tests for the login module, run them, and fix what’s broken.” |
| Work with Git | “Commit with a descriptive message and open a pull request.” |
| Tidy up the code | “Refactor this function to make it easier to read and add comments.” |
| Document | “Write a README with installation instructions and usage examples.” |
As you progress, the same tools grow with you. The official documentation also describes scenarios for teams:
- Automatic code review on every pull request, via GitHub Actions or GitLab CI/CD.
- Scheduled tasks, such as a dependency check every Monday morning, that run in the cloud even if your laptop is closed.
- From Slack to code: mention @Claude in a channel with a bug description and get a pull request back.
- Debugging web applications directly in Chrome, with access to errors in the console.
- Multiple agents in parallel, each on a part of the same large task.
Plugins, Extensions, and Related Applications
Claude Code extends through a few different mechanisms, and confusion between them is common at first. In short: plugins are the “packages” to install, skills are the instructions within them, and MCP servers are the connections to other applications.
| What It Is | What It Does | How to Use It |
|---|---|---|
| Plugin | Install skills, commands, hooks, and MCP connections at once | Run /plugin and search in the Discover tab, or browse the Claude Marketplace |
| Skill | Package a repeatable workflow, like /review-pr or /deploy-staging | A SKILL.md file in the .claude/skills/ folder of the project |
| MCP Server | Connect Claude Code to Google Drive, Jira, Slack, Notion, Figma, or a database | claude mcp add followed by the server name and address |
| Hook | Automatically run a command at each step, such as formatting code after each edit | You ask Claude to “write a hook that runs eslint after each edit” |
| CLAUDE.md | You give Claude the project rules at the beginning of each session | Run /init to generate a startup file |
Useful Plugins to Get You Started
The official marketplace, claude-plugins-official, is automatically added when you first start it in the terminal. According to the Anthropic documentation, a few plugins maintained by Anthropic are worth trying:
- commit-commands: ready-made commands for commits and working with Git.
- code-review: a code review before you push your changes.
- feature-dev: a guided flow for building new functionality.
- security-guidance: Claude checks his code for vulnerabilities himself.
- Code intelligence plugins: for typed languages (TypeScript, Java, C#), Claude immediately sees type errors after each edit.
Installation is done from a command, for example /plugin install commit-commands@claude-plugins-official. Be careful with third-party marketplaces: Anthropic does not check them, so only install plugins from sources you trust.
Integrations With Other Applications
- Editor extensions: VS Code, Cursor and JetBrains IDEs, with differences displayed directly in the editor.
- GitHub and GitLab: automatic review of pull requests and conversion of issues into code, via GitHub Actions or GitLab CI/CD.
- Slack: submit a bug from the chat and receive a pull request back.
- Claude in Chrome: Claude tests the web application in the browser and reads the errors in the console.
- Mobile app and Remote Control: follow and guide a session from your phone.
- Agent SDK: for advanced users, build your own agents based on the Claude Code engine.
How Much Does Claude Code Cost
Claude Code does not have a separate subscription: it is included in all paid Claude plans, starting at $20 per month (Pro). For a beginner, Pro is usually enough; upgrade to Max only if you often hit the usage limits.
| Plan | Price (excl. VAT) | Claude Code | Suitable For |
|---|---|---|---|
| Free | $0 | No | Only chat, without Claude Code |
| Pro | $20/month of $17/month paid annually ($200 upfront) | Yes | Beginners, personal projects, learning |
| Max 5x | $100/month | Yes, 5x more usage than Pro | Heavy daily work |
| Max 20x | $200/month | Yes, 20x more usage than Pro | Multiple agents in parallel, large projects |
| Team, Standard seat | $25/seat/month or $20 paid annually | Yes | Teams of 2–150 people |
| Team, Premium seat | $125/seat/month or $100 paid annually | Yes, 5x more usage than Standard | Heavy team developers |
| Enterprise | $20/seat/month, annually, plus API usage (minimum 20 places) | Yes | Large companies, security requirements |
| API (Console) | Pay-as-you-go, e.g. Sonnet 5.5: $2 / $10 per million tokens (input / output) | Yes | Automations, occasional use |

Things to know about limits:
- Usage resets in a 5-hour sliding window, and paid plans also have a weekly limit.
- Claude Code uses the same “budget” as conversations in the Claude app.
- When you hit the limit, you can wait for it to reset, upgrade to a higher plan, or activate additional credits, paid at API rates.
- The /usage command in Claude Code shows you what’s using the most of your limit.
Recommendations for Beginners
The basic rule: treat Claude Code like a senior colleague who you give clear tasks to and whose work you check, not like a magic wand. The tips below come mostly from the best practices guide published by Anthropic.
- Explore, plan, then write code. Press Shift+Tab until Plan mode appears: Claude reads the project and proposes a plan without changing anything. You approve the plan and only then move on to implementation. For small, one-sentence changes, you can skip the plan.
- Give it a verification method. Instead of “make a login form,” ask “make the form, write tests for invalid email and wrong password, run them, and fix what’s wrong.” With tests, Claude corrects his own mistakes.
- Create a CLAUDE.md file. Run /init and Claude generates a file with the project’s rules: test commands, code style, conventions. Keep it short; a long file ends up being ignored.
- Use Git from day one. Commit before any major task. Claude Code also saves rewind points (press Esc twice or run /rewind), but these are not a replacement for Git.
- Choose your permissions mode consciously. In recent versions, sessions start in Auto mode: a separate model checks actions and blocks risky ones, such as a force push or permanent deletion of files. As you learn, it’s worth switching to Manual mode to see and approve each step. The mode that skips all checks is only for isolated containers.
- Keep the conversation clean. Run /clear when you move on to a task unrelated to the previous one. If you’ve fixed the same mistake twice, start a new session with a more specific prompt.
- Be specific. Name the files (you can reference them with @), say what constraints there are, and show an example from the project. You can also paste screenshots of the desired design.
- Don’t accept code you don’t understand. Ask for line-by-line explanations, ask why he chose a solution, and sometimes try to write the code yourself, with Claude as a reviewer. The Explanatory response style makes him explain more about what he does.
- Protect your data. Don’t paste passwords or API keys into prompts or leave them in your code. Only install plugins from trusted sources.
- Learn from free resources too. Claude Academy has free introductory courses, such as Claude Code 101.
Want to Build Complete Apps with AI on Your Side?
Claude Code only multiplies your speed if you understand what you’re building. A developer who masters front-end, back-end, databases, and Git knows what to ask for, checks the result, and fixes what doesn’t work. Without these foundations, you end up accepting code that you can’t maintain.
NewTech Academy’s Fullstack AI Developer course takes you from the first lines of code to complete web applications, using AI tools as development teams use them today. You work on practical projects, alongside industry mentors, and leave with a portfolio that you can show to employers.

Frequently Asked Questions About Claude Code
No. Claude’s Free plan does not include Claude Code. The cheapest option is Pro, at $20/month ($17/month when paid annually), or pay-as-you-go through an Anthropic Console account.
You can start it up without any experience: you tell it what you want, and it builds. To check what it has done, fix bugs, and take a project to launch, however, you need the basics of programming. The more you know, the better the results.
Yes, Claude understands and responds in Romanian. For code, comments, and commit messages, the industry convention remains English; you can pass it as a rule in CLAUDE.md, and Claude will respect it.
The chat answers questions and generates code snippets that you copy. Claude Code works directly in the project: it reads files, modifies them, runs commands and tests. Both use the same subscription and the same usage limits.
The risk exists, but it is limited by several protections. In Manual mode, you approve each action, and in Auto mode, a separate model implicitly blocks dangerous operations, such as irreversible deletions or force pushes. Commit to Git before large tasks and you can always revert to a previous version.
