+This is a Next.js project bootstrapped with `create-next-app`, integrating with Cohere AI and powered by Edgio.
+
+## Getting Started
+
+### Install Packages
+
+```bash
+npm install
+```
+
+### Setup Environment Variables
+
+Set up environment variables in a `.env` file by copying the `.env.example` file to `.env`.
+
+```bash
+cp .env.example .env
+```
+
+Replace `YOUR_COHERE_API_KEY` with your Cohere AI API key.
+
+### Local Development Server
+
+```bash
+npm run edgio:dev
+```
+
+Open http://localhost:3000 with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses `next/font` to automatically optimize and load Inter, a custom Google Font.
+
+### Cohere AI Integration
+
+This application demonstrates a simple use case for text summarization using Cohere AI's powerful natural language processing capabilities. Users can input a text of at least 250 characters, and the app will display a summarized version of the text.
+
+To get started with the text summarization feature:
+
+1. Navigate to the home page at http://localhost:3000.
+2. Enter your text into the textarea provided.
+3. Click the `Summarize` button to see the summarized text.
+
+Please ensure you have set up your Cohere AI API key correctly in your environment variables or within the application to use the summarization feature.
+
+To learn more about Edgio, take a look at the following resources:
+
+- [Edgio Documentation](https://docs.edg.io) - learn about Edgio features
+
+## Deploy on Edgio
+
+Deploy this project on Edgio with the following command:
+
+```bash
+npm run edgio:deploy
+```
+
+Check out our [Cohere AI documentation](https://docs.edg.io/guides/v7/ai_integrations/cohere) for more details.
