## Overview

Simple Weather App is a Laravel web app that shows local weather, either based on the visitor’s IP address or a searched city. The main workflow resolves a location, requests weather by coordinates, then renders a result or search error. The README also documents the FreeGeoIP and OpenWeather integrations; the controller source confirms how those services are coordinated. Source excerpts do not show the route declaration or the API client internals, so those links reflect only documented responsibilities, not uninspected call details.

Main entry points: [`app/Http/Controllers/WeatherController.php`](https://github.com/deanhouseholder/simple-weather-app/blob/main/app/Http/Controllers/WeatherController.php) (Weather controller), [`app/Classes/FreeGeoIp.php`](https://github.com/deanhouseholder/simple-weather-app/blob/main/app/Classes/FreeGeoIp.php) (IP geolocation client), [`app/Classes/OpenWeather.php`](https://github.com/deanhouseholder/simple-weather-app/blob/main/app/Classes/OpenWeather.php) (Weather client), [`public/index.php`](https://github.com/deanhouseholder/simple-weather-app/blob/main/public/index.php) (HTTP entry)
