+# Localist Frontend (React + Vite)
+
+This directory contains the frontend application for Localist built with React + Vite.
+
+It provides an event creation form with an embedded Leaflet map and a search bar (leaflet-geosearch). The form uses react-hook-form with a Zod schema to validate and transform outgoing payloads (the schema nests flat latitude/longitude into a `location` object before sending).
+
+Quick links
+- Source: `src/`
+  - Main component: `src/components/eventForm.jsx`
+  - Validation/transform schema: `src/schemas/eventPostSchema.js`
+  - API client: `src/services/eventService.js`
+- Vite config: `vite.config.js`
+
+Prerequisites
+- Node.js (16+ recommended)
+- npm or yarn
+- Django backend running locally at http://127.0.0.1:8000 if you want the API to respond (the Vite config proxies `/api` to that address by default)
+
+Install dependencies
+```bash
+cd localist/frontend
+npm install
+# or
+yarn
