Learn 90% of Claude Code in 31 Minutes

Most of the Claude Code advice floating around right now is completely outdated. People are telling you to mess with CLAUDE.md files you don't need, pushing MCP servers that don't make sense, and generally promoting workflows that pollute your context window. Here's what actually matters if you want to get real results with Claude Code in 2026.

I've spent hundreds of hours inside Claude Code at this point. What follows is everything I wish someone had told me from day one — installation, where to use it, prompting, skills, CLI tools, context window management, and deployment. That's the full stack. Let's get into it.

How Do You Install Claude Code?

Installation takes about 60 seconds. Google "Claude Code install," and you'll land on the official documentation page. It gives you one command to run depending on your operating system. On Windows, you open PowerShell, paste the command, and run it. That's it.

But here's where people immediately get confused: where do you actually use it once it's installed?

Where Should You Use Claude Code?

You've got four main options — the terminal, the Claude desktop app, Cowork, and IDEs like VS Code, Cursor, or Antigravity. And honestly, you can't really go wrong with any of them.

Think of it as a spectrum of control:

• Terminal — Maximum control and visibility into what Claude Code is doing on your machine. Not as pretty, but powerful once you get past the initial learning curve.
• Cowork — Trades some control for a simpler, more streamlined experience. Great for straightforward tasks.
• IDE (VS Code, Cursor, etc.) — The sweet spot for most people. You get the terminal at the bottom plus a file explorer on the side so you can see files as Claude Code creates them.

For most people, I recommend using Claude Code inside VS Code. It's free, it gives you that file explorer view, and the terminal is right there at the bottom. When Claude Code creates or edits files, you can see everything in real time.

To set it up: download VS Code, open it, go to File > Open Folder, create a project folder, then open the terminal with the three-dot menu > Terminal > New Terminal.

What Permissions Setting Should You Use?

This is where people overthink things. You launch Claude Code with claude or claude --dangerously-skip-permissions. The second one unlocks the bypass permissions mode.

Here's the breakdown of the three permission levels:

• Default — Claude Code asks permission for every single file change. Safe, but painfully slow.
• Accept Edits On — Claude Code can edit files freely but still asks before running shell commands. This is where I'd start if you're new.
• Bypass Permissions On — Full autonomy. Claude Code does whatever it needs without asking. Sounds scary, but Anthropic's own data shows that most power users run this mode.

I've used Claude Code for hundreds of hours with bypass permissions on and have never had it delete files or cause damage. But start with Accept Edits On until you're comfortable, then graduate to bypass.

How Do You Prompt Claude Code Effectively?

Look, prompting is the single most important skill you can develop with Claude Code. Everything else is secondary. And most people get this wrong by being way too vague.

Here's the framework that works:

1. Use Plan Mode

When you toggle plan mode on, Claude Code won't just sprint off and build whatever it thinks you want. It asks clarifying questions first. This is massive because a vague prompt like "build me a kanban board" will produce average results. Plan mode forces a conversation that fills in the gaps.

2. Focus on the Outcome, Not the Task

Don't say "build me a kanban board." Say something like: "The goal is to create a board that lets me organize previous content and plan future content, track performance metrics like views and engagement, and manage content across multiple platforms."

The why matters more than the what. For a landing page, you'd say "the point is to drive visitors to fill out a signup form" rather than just "build a landing page."

3. Give Examples

Words are good. Screenshots are better. Code repos are best. If you're building something visual, go find a design you like on Dribbble, screenshot it, and drag it directly into the Claude Code chat window. Visual references dramatically improve output quality.

4. Ask Open-Ended Expert Questions

This one is huge and most people skip it entirely. Ask things like:

• "What would an expert in kanban boards be thinking about here?"
• "What am I not considering?"
• "What are the unintended consequences of this approach?"

Here's the thing — AI lets us build in domains where we have zero expertise. That's both its superpower and its trap. You don't know what you don't know. By prompting Claude Code to think like an expert and challenge your assumptions, you get outputs that are leagues better than the default.

What Are Skills and How Do You Use Them?

Skills are just text prompts that tell Claude Code how to do a specific thing in a specific way. That's it. No magic, no complexity — they're instructions that improve Claude Code's output in a targeted area.

Two flavors:

1. Performance skills — Teach Claude Code to do something better than it already does (like front-end design)
2. Workflow skills — Bundle multi-step processes you repeat often into a single trigger

The best example is front-end design. Without a skill, Claude Code produces generic, boring UI — purple gradients, standard layouts, forgettable stuff. With the front-end design skill (an official Anthropic skill on GitHub), the same prompt produces dramatically better results. The gap is enormous.

To install a skill:

1. Type /plugin in Claude Code to open the plugin library
2. Search for the skill you want (e.g., "front-end design")
3. Install it and reload plugins when prompted

To use a skill, you have two options:

• Direct invocation: Type /frontenddesign followed by your prompt for a 100% trigger rate
• Natural language: Just describe what you want and Claude Code will recognize it should use the relevant skill

How Do You Manage the Context Window?

This is where people silently sabotage themselves without realizing it. Claude Code has a budget of 1 million tokens, and performance degrades as you use more of it.

Tokens are essentially words — every word you send, every word you receive, every tool call, every skill invocation costs tokens. Here's what matters:

• The first 200,000 tokens (about 20%) is the gold zone. Performance is excellent here.
• After 200K, you start seeing decline. It gets progressively worse.
• At 1 million tokens, Opus 4.6 drops to about 78% effectiveness according to Anthropic's own benchmarks.

The fix is simple: use /clear aggressively. This resets your entire context window. Yes, Claude Code "forgets" the conversation, but it doesn't forget your project — all your files are still right there. It just re-reads what it needs.

If you were deep in a specific conversation and need to carry something over, just ask Claude Code for a summary before you clear, then paste it into the fresh session.

To monitor your usage, type /context to see your current token count. Better yet, tell Claude Code to create a permanent status bar below the prompt that shows your context window usage in real time. When you hit around 20%, clear it and start fresh.

What Are CLI Tools and Why Do They Matter?

CLI (command line interface) tools are where Claude Code gets seriously powerful. These are programs that live in the terminal — the same place Claude Code lives — so Claude Code can control them directly with almost zero overhead.

You've probably heard about MCPs. CLI tools are replacing them. They're more efficient, lower token cost, and just work better with Claude Code's architecture.

Real examples:

• Supabase CLI — Claude Code can create databases and authentication systems on your behalf
• Playwright CLI — Claude Code can open browsers and test your web apps automatically
• GitHub CLI — Push code and manage repos through natural language
• Vercel CLI — Deploy sites without leaving the terminal

Most CLI tools have two components: the tool itself (which you install) and a skill (which teaches Claude Code how to use it well). Both are usually found on the tool's GitHub repo.

For example, to install Playwright, you just copy the GitHub URL, paste it into Claude Code, and say "install the Playwright CLI following these instructions." Three lines of code and you've got browser automation. Then you can say something like "use Playwright to test our kanban board — come up with two tests and use headed browsers" and Claude Code will open actual browser windows and test everything automatically.

How Do You Deploy Your Project?

Once you've built something and tested it locally, getting it on the internet is a two-step process: push to GitHub, then deploy through Vercel. Both are free.

Step 1: Push to GitHub

1. Create a new repository on GitHub (can be private)
2. Copy the repo URL
3. Tell Claude Code: "Commit and push to [URL]"
4. First time, it'll ask you to authenticate — takes under 60 seconds

Commit creates a save point. Push sends that save to GitHub. That's all that's happening.

Step 2: Deploy on Vercel

1. Sign up at vercel.com using your GitHub credentials
2. Go to Projects > Add New Project
3. Your GitHub repo will auto-populate on the left
4. Click Import, then Deploy

If you get deployment errors, just copy the error message, paste it into Claude Code, and it'll fix whatever needs fixing.

The beautiful part: once this pipeline is set up, any changes you make in Claude Code automatically flow through. You commit and push, GitHub updates, Vercel detects the change, and your live site redeploys. That's the Claude Code > GitHub > Vercel framework.

FAQ

Do I need to know how to code to use Claude Code?

No. You never have to write a single line of code. But — and this is important — you do need to understand software engineering concepts over time. When Claude Code suggests Next.js or Tailwind, you should eventually understand what those are and why they matter. Claude Code is an infinitely patient tutor. Ask it to explain anything you don't understand. The people who just hit "recommended" on everything without learning will eventually hit a wall.

How is Claude Code different from using the Claude chatbot?

Claude Code lives in your terminal and has direct access to your file system. It can create files, edit code, run shell commands, control CLI tools, and interact with your entire project. The chatbot is a conversation in a browser. Claude Code is a hands-on-keyboard collaborator that can actually build things on your machine.

What should I build first?

Start with something visual and simple — a landing page, a personal dashboard, or a kanban board like the example in this guide. The goal is to get comfortable with the prompting workflow, understand how plan mode works, and see the full cycle from building to deployment. Don't start with a complex SaaS app on day one.

Is bypass permissions mode actually safe?

In hundreds of hours of use, I've never had Claude Code cause damage with bypass permissions on. Anthropic's own data shows most power users run this mode. That said, start with Accept Edits On if you're uncomfortable. Graduate to bypass once you trust the workflow and understand what Claude Code is doing.

How often should I clear the context window?

Anytime you finish a distinct task or hit around 20% usage (roughly 200,000 tokens). Think of each clear as starting a fresh, high-performance session. Your project files persist — Claude Code just re-reads what it needs. Frequent clears keep your outputs sharp.
