-E-ink solar panel screen showing info, this is the api for it. Low effort code
+# This [![Build and Deploy](https://github.com/Myxelium/HomeScreen/actions/workflows/build.yml/badge.svg)](https://github.com/Myxelium/HomeScreen/actions/workflows/build.yml)
+Core api and Esp32 code for displaying weather data and public transport information on a e-ink display.
+
+<img width="800" height="480" alt="image" src="https://github.com/user-attachments/assets/ef5af0c6-ea3a-494d-b2af-3de6e70b3e6a" />
+
+## Features 😺
+- Display current weather data
+- Display public transport information
+- Display time and date
+
+## Requirements 🫥
+- ESP32 board
+- E-ink display (e.g. Waveshare 7.5 inch)
+
+# Installation
+
+This section provides instructions for setting up and running the HomeApi project.
+
+## Prerequisites
+
+- [.NET 9.0 SDK](https://dotnet.microsoft.com/download/dotnet/9.0) or later
+- Docker (optional, for containerized deployment)
+- Git (to clone the repository)
+
+## Option 1: Local Development Setup
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/Myxelium/HomeScreen.git
+   cd HomeApi
+   ```
+
+2. Restore dependencies:
+   ```bash
+   dotnet restore
+   ```
+
+3. Build the project:
+   ```bash
+   dotnet build
+   ```
+
+4. Run the application:
+   ```bash
+   dotnet run
+   ```
+
+The API will be available at `http://localhost:5000`.
+
+## Option 2: Docker Deployment
+
+1. Build the Docker image:
+   ```bash
+   docker build -t homeapi .
+   ```
+
+2. Run the container:
+   ```bash
+   docker run -d -p 5000 --name homeapi homeapi
+   ```
+
+The API will be accessible at `http://localhost:5000`.
+
+## Configuration
+
+The application uses the standard .NET configuration system. You can modify settings in:
+
+- `appsettings.json` - Default configuration
+- `appsettings.Development.json` - Development environment configuration
+
+API endpoints:
+- Weather data: GET `/home`
+- Generated image: GET `/home/default.jpg`
+- Configuration data: GET `/home/configuration`
+- Departure board: GET `/home/departure-board`
+
+## API Documentation
+
+When running, API documentation is available through Scalar at `/scalar`.
