Welcome

Let's get you set up.

In about 15 minutes you'll have Claude installed, signed in, connected to Unreal — and you'll know exactly where to go next. No experience needed; every step shows you a picture of what your screen should look like.

First question: what kind of computer are you on?

Install · Open the Terminal

Open the Terminal app.

Hold the ⌘ command key and press the space bar. A search bar appears in the middle of your screen. Type terminal and press Enter.

Spotlight Search — ⌘ + Space
terminal
>_ Terminal Applications / Utilities

A window with plain text opens. That's the terminal. It's supposed to look boring.

Install · Run the installer

Copy, paste, Enter.

Select the whole line below, copy it (⌘C), click inside the terminal window, paste it (⌘V), then press Enter.

copy this › curl -fsSL https://claude.ai/install.sh | bash

The terminal prints progress text for a minute. When it stops, it should look like this:

Terminal
$ curl -fsSL https://claude.ai/install.sh | bash

✔ Claude Code installed successfully.
Restart your terminal, then run: claude
Install · Check it worked

Restart the terminal, then check.

Quit Terminal completely (⌘Q), open it again the same way (⌘ + space, "terminal", Enter), then type this and press Enter:

type this › claude --version
Terminal
$ claude --version
2.1.x (Claude Code)

Any version number = success, keep going. "command not found" = you skipped the restart — close the terminal fully and try again.

Install · Open PowerShell

Open PowerShell.

Press the Windows key (bottom row, four squares). Type powershell and press Enter.

Start Menu — press the Windows key and type
powershell
>_ Windows PowerShell App

A blue window opens, ending in PS C:\Users\yourname>. The "PS" at the start matters — it means you're in the right place.

Install · Run the installer

Copy, paste, Enter.

Select the line below, copy it (Ctrl+C), click inside the blue window, right-click to paste (that's how PowerShell pastes), then press Enter.

copy this › irm https://claude.ai/install.ps1 | iex
Windows PowerShell
PS C:\Users\you> irm https://claude.ai/install.ps1 | iex

Claude Code installed successfully.
Restart PowerShell, then run: claude

"irm is not recognized"? Your window says C:\ without the PS — that's Command Prompt. Close it and redo the previous step.

Install · One companion tool

Install Git for Windows.

In your web browser, go to git-scm.com/downloads/win, download the installer, run it, and click Next through every screen — the defaults are all correct.

Why: this quietly gives Claude a better set of tools for running commands. You'll never touch it directly. It takes two minutes.

Install · Check it worked

Restart PowerShell, then check.

Close the blue window, open it again (Windows key, "powershell", Enter), then type this and press Enter:

type this › claude --version
Windows PowerShell
PS C:\Users\you> claude --version
2.1.x (Claude Code)

Any version number = success, keep going. An error = close the window fully, open a fresh one, try again.

Sign in · Find the project

Open a terminal inside the project folder.

Claude is most powerful when it's started inside our Unreal project folder — that's where it can see the code, our shared skills, and the Unreal connection. Your lead told you where the project folder lives.

On your Mac: find the project folder in Finder, right-click it, and choose New Terminal at Folder (near the bottom of the menu).

On your PC: open the project folder in File Explorer, click once in the address bar at the top, type powershell over what's there, and press Enter.

A terminal opens already "standing in" that folder. That's the whole trick.

Using the Claude Code desktop app instead? Even easier: open the app and choose the project folder when it asks where to work. Then skip ahead — everything else on this walkthrough looks the same in the app.

Sign in · First launch

Type claude and press Enter.

type this › claude
Terminal — your project folder
$ claude

Opening your browser to sign in…

Your web browser pops open a sign-in page. Sign in with your Lasting Light account — the one your lead gave you, not a personal one.

First time only: Claude also asks you to approve this project's connections (the MCP servers). Say yes — they're ours, committed in the repo.

Sign in · Say hello

Say something.

Back in the terminal there's a box waiting for your message. Type like you'd text a colleague — no special language needed:

you › Hi! I'm new. What is this project, in one paragraph?

If Claude answers with a summary of our game — congratulations, Claude Code is fully working on your machine. Two short connections left.

Connect · Unreal

Unreal: already wired. Just check the light.

The Unreal connection ships with the repo — an editor plugin plus a config file Claude reads automatically. You install nothing. The one rule: the Unreal editor must be open for Claude to have hands in it.

1. Open our project in the Unreal editor (if it asks to enable or rebuild our MCP plugin, say yes).

2. In your Claude session, type /mcp and press Enter. You want to see this:

Claude Code (desktop app)
/mcp

3. Prove it end to end:

you › Using the Unreal MCP, list the actors in the currently open level.

Shows as failed? The editor probably isn't open, or the plugin isn't enabled (in Unreal: Edit → Plugins → find our MCP plugin → check the box → restart). The Setup page has the full checklist.

Learn · Skills

Skills: our playbooks, preloaded.

A skill is a how-to guide written for Claude instead of a human — it packages the exact way Lasting Light does something: our real build commands, our naming rules, our checklists. Skills live in the repo, so everyone's Claude follows the same playbook, and when one person improves a skill, the whole team gets it.

Using them requires almost nothing from you. Describe the task and Claude picks the right skill automatically. To call one deliberately, type / and its name, or just say it in plain English:

you › /log-and-crash-triage — here's the crash from last night [paste]
you › Use the asset-lint skill on everything I have checked out.

The six everyone uses, whatever your desk:

build-and-cook
Build or check the project, and fix what breaks — also answers "is the nightly green?"
verify-in-editor
Makes Claude prove a change in the running game before calling it done.
log-and-crash-triage
Paste any error or crash; get back what broke, why, and the likely fix.
source-control
Clean changelists, binary-file locks, and untangling "who has this checked out?"
meeting-to-action
Transcript or messy notes in — decisions, owners, and action items out.
spec-to-plan
Turns a doc into a task breakdown with dependencies and open questions.

Your department page (last step) adds the specialist skills for your seat — and the full catalog lives in the Skill Library, filterable by department. Notice something a skill should know? Add it — that's the whole flywheel.

Learn · Models & effort

Two models, one habit.

Claude comes in different models — same teammate, different gears — and each runs at an effort level (how long it thinks before acting). You only need one habit:

For planning — Fable 5 · high

Fable 5

The deepest reasoner. Use it on high effort to plan features, make architecture calls, and untangle the truly hairy bugs. Slower, worth it.

For doing — Sonnet 5 · extra (xhigh)

Sonnet 5

Fast and sharp. Use it on extra-high effort to execute the plan — write the code, run the lint pass, do the task. Our everyday workhorse.

Swapping takes five seconds: in the desktop app, click the model name next to the message box and pick from the menu (or type /model — same thing):

Claude Code (desktop app) — model picker
Reply to Claude…Fable 5 · high

The rhythm: plan in Fable 5 (high) → swap → build in Sonnet 5 (extra). You'll do it without thinking within a week.

Learn · Approvals & modes

It asks permission a lot. Here's the fix.

Out of the box, Claude asks approval before editing files or running commands. Great safety default — but inside our own project it means clicking "yes" forty times an hour. We recommend auto mode for day-to-day work.

In the desktop app, click the mode control next to the message box and pick (in the terminal, Shift + Tab cycles the same modes):

Claude Code (desktop app) — permission mode
Reply to Claude…⏵⏵ autoFable 5 · high

Plan mode is the third stop on that same cycle — Claude researches and writes a full plan, and edits nothing until you approve it. Pair it with Fable 5 for anything big; approve the plan, then flip to auto mode + Sonnet 5 and let it build.

Auto mode isn't a blank check — genuinely risky or destructive actions still ask, and everything Claude does still goes through normal review before it ships.

Learn · Connectors

Connectors: MCPs with a one-click switch.

The Unreal connection you just checked is an MCP wired into our repo — connectors are the same idea with a one-click switch. The Claude app has a gallery of them: Google Drive, Slack, Gmail, Calendar, Notion, and more. Flip one on, sign in with your work account, and Claude can read your meeting notes, draft in your docs, and pull from your channels.

Where: Claude app → Settings → Connectors → enable what you use. That's the whole setup — no commands.

Claude — Settings › Connectors

In Claude Code, type /mcp anytime to see everything connected to your current session — connectors and hand-added MCPs side by side.

Two rules: work accounts only (never personal), and ask in the tools channel before enabling anything unusual. Connectors are the everyday-work superpower — meetings, docs, and email are where most people save their first hours.

Last step

You're set up. What's your department?

Each department has its own page: what Claude does for your seat, the playbooks you'll use, and real prompts to try today. Pick yours and we'll take you there.
