Getting Started

← Docs index

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:

Zero install (recommended)

Run Fusion directly from npm without a global install:

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)

curl -fsSL https://runfusion.ai/install.sh | sh
fusion dashboard

Homebrew (macOS & Linux)

brew tap runfusion/fusion
brew install fusion
fusion dashboard            # or: fn dashboard

npm global

npm install -g @runfusion/fusion
fn dashboard                # or: fusion dashboard

From source (development)

pnpm dev dashboard

After installing, verify the CLI is available:

fn --help
# or
fusion --help

Optional — Pi extension: To use Fusion tools inside Pi chat sessions, run pi install npm:@runfusion/fusion. This adds a /fn command and Fusion tools within pi. You do not need this to use Fusion — the global CLI and dashboard work standalone.

Initialize a Project

In each repository you want Fusion to manage, run:

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:

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)
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.

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 2–5 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

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
