+# Battlesnake TypeScript Starter Project
+
+An official Battlesnake template written in TypeScript. Get started at [play.battlesnake.com](https://play.battlesnake.com).
+
+![Battlesnake Logo](https://media.battlesnake.com/social/StarterSnakeGitHubRepos_TypeScript.png)
+
+This project is a great starting point for anyone wanting to program their first Battlesnake in TypeScript. It can be run locally or easily deployed to a cloud provider of your choosing. See the [Battlesnake API Docs](https://docs.battlesnake.com/api) for more detail. 
+
+[![Run on Replit](https://repl.it/badge/github/BattlesnakeOfficial/starter-snake-typescript)](https://replit.com/@Battlesnake/starter-snake-typescript)
+
+## Technologies Used
+
+This project uses [TypeScript](https://www.typescriptlang.org/), [Node.js](https://nodejs.org/en/), and [Express](https://expressjs.com/). It also comes with an optional [Dockerfile](https://docs.docker.com/engine/reference/builder/) to help with deployment.
+
+## Run Your Battlesnake
+
+Install dependencies using npm
+
+```sh
+npm install
+```
+
+Start your Battlesnake
+
+```sh
+npm run start
+```
+
+You should see the following output once it is running
+
+```sh
+Running Battlesnake at http://0.0.0.0:8000
+```
+
+Open [localhost:8000](http://localhost:8000) in your browser and you should see
+
+```json
+{"apiversion":"1","author":"","color":"#888888","head":"default","tail":"default"}
+```
+
+## Play a Game Locally
+
+Install the [Battlesnake CLI](https://github.com/BattlesnakeOfficial/rules/tree/main/cli)
+* You can [download compiled binaries here](https://github.com/BattlesnakeOfficial/rules/releases)
+* or [install as a go package](https://github.com/BattlesnakeOfficial/rules/tree/main/cli#installation) (requires Go 1.18 or higher)
+
+Command to run a local game
+
+```sh
+battlesnake play -W 11 -H 11 --name 'TypeScript Starter Project' --url http://localhost:8000 -g solo --browser
+```
+
+## Next Steps
+
+Continue with the [Battlesnake Quickstart Guide](https://docs.battlesnake.com/quickstart) to customize and improve your Battlesnake's behavior.
+
+**Note:** To play games on [play.battlesnake.com](https://play.battlesnake.com) you'll need to deploy your Battlesnake to a live web server OR use a port forwarding tool like [ngrok](https://ngrok.com/) to access your server locally.
