## Requirements

> **Using the [self-contained installer](#quick-start)?** You can skip the Node and pnpm
> requirements below — `install.sh` / `install.ps1` download a pinned, local Node and activate
> the right pnpm for you. The only thing you'd still want is an LLM server to actually play.

- **Node.js 20+** (developed on Node 24). Uses Node's built-in `node:sqlite`, so installation
  never compiles a native C addon.
- **pnpm** — the repo pins **`pnpm@11.7.0`** via `packageManager`, so running `corepack
  enable` once will fetch the right version automatically (or `npm i -g pnpm`).
- *(Optional, but basically needed to actually play)* an **OpenAI-API-compatible** LLM server, either local or a cloud API.

## Quick start

The fastest way in is the **self-contained installer**. It needs *no prerequisites* — not
even Node or pnpm. It downloads a pinned, official Node.js into a local `./.runtime/node`
folder (verified against nodejs.org's SHA-256 checksums, nothing installed system-wide),
activates the exact pnpm pinned in `package.json` via corepack, installs dependencies, and
seeds the sample database. Then a matching `run` script starts the app.

**macOS / Linux**

```bash
./install.sh      # one-time setup (downloads Node locally, installs, seeds)
./run.sh          # start the server + web client
```

**Windows**

```powershell
powershell -ExecutionPolicy Bypass -File .\install.ps1   # one-time setup
.\run.bat                                                # start the app
```

> **Unattended/CI?** Pass `-y`/`--yes` to `install.sh` (or `-Yes` to `install.ps1`), or set
> `HEARTMORROW_YES=1`, to skip the Node-download confirmation prompt.

> **📱 Works on Termux, too.** The Linux installer runs as-is under
> [Termux](https://termux.dev/) on Android — `./install.sh` then `./run.sh` — so you can host
> Heartmorrow right on your phone and play it from the device's browser. (Point it at a local
> or remote LLM the same way you would anywhere else.)

Both installers are **idempotent** — re-run them anytime; they skip the Node download if the
vendored copy is already present.

Then open **http://localhost:5173**.

### Manual install

Already have **Node.js 20+** and **pnpm**? Skip the installer and run the steps yourself:

```bash
