+# create-spacetime
+
+## Overview
+
+This package contains the official CLI tool for creating SpacetimeDB projects. The CLI allows you to quickly scaffold new SpacetimeDB applications with a template of your choice (React frontends with Rust or C# backends).
+
+## Installation
+
+To create a new SpacetimeDB project:
+
+```bash
+npm create spacetime@latest
+```
+
+## Usage
+
+To create a project you can run the interactive setup or specify options directly.
+
+```bash
+npm create spacetime@latest my-spacetime-app -- -t rust
+```
+
+Skip interactive prompts with `-y` (defaults server language to Rust):
+
+```bash
+npm create spacetime@latest my-spacetime-app -- -y
+```
+
+The `-t` flag selects your server language template.
+
+Available templates:
+
+- `rust` - Rust server with React client
+- `csharp` - C# server with React client
+
+Create in your current directory using `.` as the project name:
+
+```sh
+npm create spacetime@latest .
+```
+
+Use a local SpacetimeDB server instead of Maincloud:
+
+```bash
+npm create spacetime@latest my-spacetime-app -- --local
+```
+
+## What You Get
+
+Creates a full-stack SpacetimeDB app with server module and React frontend, including build scripts and example chat app.
+
+## Requirements
+
+- Node.js 18+ and npm 8+
+- SpacetimeDB CLI (optional for creation, required for Maincloud deployment) - [spacetimedb.com/install](https://spacetimedb.com/install)
+
+## Running The Project
+
+After project creation:
+
+```bash
+cd my-spacetime-app
+npm run dev
+```
+
+Your React app will be available at `http://localhost:5173`.
+
+To deploy your SpacetimeDB module:
+
+```bash
+npm run local    # Local deployment
+npm run deploy   # Deploy to Maincloud
+```
