+## Setting up your development environment
+
+This guide will help you set up your development environment to start contributing to homarr.
+
+### Prerequisites
+

+
+8. Start the development server with `pnpm dev` and wait for a message that says `✓ Ready in 10.7s`
+
+9. Open your browser and navigate to [http://localhost:3000](http://localhost:3000). (Loading the page might take up to 2 minutes the first time)
