What You’ll Be Doing
Before we start, here’s what you’ll do:
Step 1: Open a special app on your computer called “Terminal” (Mac/Linux) or “PowerShell” (Windows)
- This is a text-based window where you type commands
- Don’t worry - we’ll show you exactly what to type
- You just copy, paste, and press Enter
Step 2: Install Claude Code (your AI coding assistant)
- Just one command
- Takes 30 seconds
Step 3: Let Claude set up everything else
- Tell Claude what you want
- It installs the rest and creates your first app
- Done!
Ready? Let’s go!
Step 1: Open Your Terminal or PowerShell

-
Click on it or press Enter
- A white or black window opens
- You’ll see some text and a blinking cursor
- This is your terminal! ✅
What you’ll see:
-
Something like:
MacBook-Pro:~ yourname$or just% -
A blinking cursor waiting for you to type
-
This is normal! Leave this window open.
Step 2: Install Claude Code
Now you’re going to copy and paste ONE command.
How to copy and paste in terminal:
- To paste: Right-click and choose “Paste”, OR press
Command + V(Mac) orCtrl + V(Windows/Linux) - Then press

4. Close Terminal and open it again
- Click the red X (top-left)
- Follow Step 1 again to open a fresh Terminal
5. Verify it worked - Type this:
claude --version
Press Enter. You should see: claude-cli 0.x.x
✅ Success! Continue to Step 3 below.

- Wrangler (publish your app to the world)
- Your first app running!
Copy and paste this into Claude:
Hi! I'm new to coding and want to build apps with the ONE Platform.
Can you please help me set up my computer? I need:
- Node.js (so I can run apps)
- Git (to save my work)
- Bun (I heard it's really fast!)
- Wrangler (to publish my apps online)
Then create my first project using: npx oneie agent
Take your time and explain everything simply, like I'm 5 years old! 😊
Press Enter. Claude will:
- Check what’s already on your computer
- Install what’s missing (asks first)
- Create your first app
- Show you how to see it in your browser
⏱️ Takes 2-3 minutes
Why these tools?

Why Is This So Easy?
Traditional way to become a developer:
- Research which tools you need (confusing!)
- Install 10+ tools manually (each with its own installer)
- Configure them to work together (breaks easily)
- Read hundreds of pages of documentation
- Spend weeks learning commands
- Get stuck on cryptic errors alone
- Give up
The ONE Platform way:
- Install Claude (30 seconds - one command)
- Choose your setup path (minimal or full)
- Tell Claude what you want (copy one prompt)
- Claude detects your OS and installs everything
- Claude configures tools to work together
- Ask Claude when stuck
- Build apps in minutes
You have an AI assistant who:
- Knows every operating system (Mac, Windows, Linux)
- Installs tools the right way for your OS
- Configures everything to work together
- Explains what each tool does and why you need it
- Fixes errors for you (with actual solutions)
- Teaches you as you go (patient and clear)
- Never judges or gets impatient (even if you ask 100 times)
Even better with npx oneie agent:
- Claude runs this command to create your project
- Zero questions asked - it detects everything automatically
- Reads your git config, infers from conversation
- Creates project in 5-10 seconds
- No context switching, no forms to fill out
