+# Deno Example for RivetKit
+
+Example project demonstrating basic actor state management and RPC calls with [RivetKit](https://rivetkit.org) using Deno runtime.
+
+[Learn More →](https://github.com/rivet-dev/rivetkit)
+
+[Discord](https://rivet.dev/discord) — [Documentation](https://rivetkit.org) — [Issues](https://github.com/rivet-dev/rivetkit/issues)
+
+## Getting Started
+
+### Prerequisites
+
+- Deno
+
+### Installation
+
+```sh
+git clone https://github.com/rivet-dev/rivetkit
+cd rivetkit/examples/deno
+pnpm install
+```
+
+**Notice:** We use `pnpm install` here as Deno offers compatability with package.json via npm/pnpm. Some packages used in rivetkit are simpler to install with npm/pnpm.
+
+### Development
+
+```sh
+deno task dev
+```
+
+Run the connect script to interact with the counter:
+
+```sh
+deno task connect
+```
