+# Design
+
+## Overview
+
+The Disfactory frontend uses [Vue.js 2.x](https://v2.vuejs.org/) as the main framework. It is a single-page application (SPA) that communicates with the [backend](https://github.com/Disfactory/Disfactory) API server.
+
+For the map, we use [OpenLayers](https://openlayers.org/) as the map library. The map is rendered in the [`Map.vue`](./src/components/Map.vue) component, with [`map.ts`](./src/lib/map.ts) as the main logic for the map.
+
+## Libraries
+
+- [Vue.js 2.x](https://v2.vuejs.org/)
+  - Vue composition API
+- [OpenLayers](https://openlayers.org/)
+- [Vuetify 2.x](https://v2.vuetifyjs.com/): Material Design component framework for Vue.js. Most of the UI components are built with Vuetify.
+
+## Directory Structure
+
+- `public/`: Static files
+- `src/`: Main source code directory
+  - `components/`: Vue components
+  - `lib/`: Libraries and utilities
