-This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
-
-## Getting Started
-
-First, run the development server:
-
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
-```
+# Flagd-ui
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+This application provides a user interface for configuring the feature flags of the flagd service.
 
-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`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
-
-## Learn More
+This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
 
-To learn more about Next.js, take a look at the following resources:
+## Running the application
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+The application can be run with the rest of the demo using the documented docker compose or make commands.
 
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+## Local development
 
-## Deploy on Vercel
+To run the app locally for development you must copy `src/flagd/demo.flagd.json` into `src/flagd-ui/data/demo.flagd.json`
+(create the directory and file if they do not exist yet). Make sure you're in the `src/flagd-ui` directory and run
+the following command:
 
-The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+```bash
+npm run dev
+```
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
+Then you must navigate to `localhost:4000/feature`.
