# Getting Started
[← Docs index](./README.md)
This guide walks you from install to your first task in Fusion.
## Install Fusion
Choose one of these install methods from the [README quick start](../README.md#quick-start):
### Zero install (recommended)
Run Fusion directly from npm without a global install:
```bash
npx runfusion.ai
```
This launches the dashboard immediately. You can also run subcommands the same way (for example, `npx runfusion.ai task create "fix X"`).
### One-line installer (macOS & Linux)
```bash
curl -fsSL https://runfusion.ai/install.sh | sh
fusion dashboard
```
### Homebrew (macOS & Linux)
```bash
brew tap runfusion/fusion
brew install fusion
fusion dashboard # or: fn dashboard
```
### npm global
```bash
npm install -g @runfusion/fusion
fn dashboard # or: fusion dashboard
```
### From source (development)
```bash
pnpm dev dashboard
```
After installing, verify the CLI is available:
```bash
fn --help
# or
fusion --help
```
## Initialize a Project
In each repository you want Fusion to manage, run:
```bash
fn init
```
On fresh init, Fusion also installs its bundled `fusion` skill into supported agent homes (`~/.claude/skills/fusion`, `~/.codex/skills/fusion`, `~/.gemini/skills/fusion`) when those targets are missing. Existing installs are left untouched.
## First Run and Onboarding
Start the dashboard:
```bash
fn dashboard
```
On first launch, Fusion opens an onboarding wizard with three steps:
1. **AI Setup** — choose a provider and authenticate (you only need one to start). Anthropic/Claude and OpenAI Codex support direct OAuth login in onboarding and Settings, while **Anthropic — via Claude CLI** remains available as a separate optional path. Deprecated Google Gemini CLI / Antigravity entries are hidden; Google/Gemini API key, Google Generative AI, Vertex, and Cloud Code options remain available.
2. **GitHub (Optional)** — connect GitHub for issue import and PR workflows
3. **First Task** — create your first task or import one from GitHub
The wizard is dismissible and non-blocking. You can skip it and continue using Fusion, then reopen it later from **Settings → Authentication**.
If a provider login gets stuck in progress (for example GitHub Copilot/device-code sign-in), use **Cancel** on the provider card in onboarding or in **Settings → Authentication**, then retry immediately — no dashboard restart is required.
On startup, Fusion prints an `Open:` URL that includes a bearer token (for example, `http://localhost:4040/?token=fn_...`). Open that URL to sign in quickly.
## Create Your First Task
Create tasks from the board or CLI.
### Option A: Quick Entry (Board)
1. Type a short request in the quick entry input.
2. Press Enter.
3. Task appears in **Planning** and the planning agent generates `PROMPT.md`.
### Option B: Plan Mode (Board)
Use the 💡 button to open AI planning mode:
- Fusion asks clarifying questions
- Produces a structured summary
- Lets you create one task or multiple dependency-linked tasks
### Option C: Subtask Breakdown (Board)
Use the 🌳 button to generate 25 subtasks, reorder them, and link dependencies before creating tasks.
You can also use expanded board controls (Refine, Deps, Attachments, model overrides, agent assignment) or the CLI (`fn task create`, `fn task plan`) when needed.
## Understand the Task Lifecycle
Fusion uses six columns:
1. **Planning** — raw idea; AI writes plan
2. **Todo** — planned and queued
3. **In Progress** — executor implements in a dedicated worktree
4. **In Review** — implementation complete, awaiting merge/finalization
5. **Done** — merged and complete
6. **Archived** — retained for history, optionally cleaned up from filesystem
## Daily CLI Commands
```bash
fn task list
fn task show FN-001
fn task logs FN-001 --follow --limit 50
fn task steer FN-001 "Prefer existing utility functions"
fn task pause FN-001
fn task unpause FN-001
```
