# Multica
AI-native task management platform — like Linear, but with AI agents as first-class citizens.
## Prerequisites
- [Node.js](https://nodejs.org/) (v20+)
- [pnpm](https://pnpm.io/) (v10.28+)
- [Go](https://go.dev/) (v1.26+)
- [Docker](https://www.docker.com/)
## Quick Start
```bash
# 1. Install dependencies
pnpm install
# 2. Copy environment variables for the shared main environment
cp .env.example .env
# 3. One-time setup: start DB and run migrations
make setup
# 4. Optional: load example data
make seed
# 5. Start backend + frontend
make start
```
Open your configured `FRONTEND_ORIGIN` in the browser. By default that is [http://localhost:3000](http://localhost:3000).
Default behavior now prefers the shared main environment in `.env`. If you want an isolated environment for a Git worktree, generate `.env.worktree` and use the explicit worktree targets:
```bash
make worktree-env
make setup-worktree
make start-worktree
```
This lets you keep `.env` connected to your main database while using `.env.worktree` only for isolated feature testing.
