+GitLink conference frontend built with [Umi](https://umijs.org/) and Ant Design.
+
+## Getting Started
+
+Install dependencies:
+
+```bash
+npm ci
+```
+
+Prepare Umi generated files:
+
+```bash
+npm run setup
+```
+
+Start the development server:
+
+```bash
+npm run dev
+```
+
+Build the production bundle:
+
+```bash
+npm run build
+```
+
+## Project Layout
+
+- `src/pages`: page-level routes.
+- `src/layouts`: application layouts.
+- `src/components`: reusable UI components.
+- `src/constants`: shared constants.
+- `src/utils`: common utility functions.
+- `public`: static assets served by Umi.
+
+## Local Configuration
+
+Local-only files such as `.env.local`, `.umirc.local.ts`, and
+`config/config.local.ts` are ignored by Git. Keep machine-specific values there
+instead of committing them to the repository.
