+# Arcjet example: Express.js
+
+[Arcjet](https://arcjet.com) helps developers protect their apps in just a few
+lines of code. Bot detection. Rate limiting. Email validation. Attack
+protection. Data redaction. A developer-first approach to security.
+
+This is an example Express.js application demonstrating how to protect a website
+from abuse.
+
+## Features
+
+- [Bot protection](https://docs.arcjet.com/bot-protection/quick-start) shows how
+ the site can be protected from automated clients.
+- [Rate limiting](https://docs.arcjet.com/rate-limiting/quick-start) shows a
+ rate limit configuration that limits the number of requests from a single IP.
+- [Attack protection](https://docs.arcjet.com/shield/quick-start) demonstrates
+ Arcjet Shield, which detects suspicious behavior, such as SQL injection and
+ cross-site scripting attacks.
+
+## Run locally
+
+1. [Register for a free Arcjet account](https://app.arcjet.com).
+
+2. Install dependencies:
+
+```bash
+npm ci
+```
+
+3. Rename `.env.local.example` to `.env.local` and add your Arcjet key.
+
+4. Start the dev server
+
+```bash
+npm run start
+```
+
+5. Open [http://localhost:3000](http://localhost:3000) in your browser.
