 # Flowboard — Project Management System
 
-Flowboard is a project management system created using React and .NET Web API, utilizing Fluent UI components.
+A comprehensive project management solution designed to streamline workflow and team collaboration. Features include interactive kanban boards, real-time task updates, and robust user management. The frontend uses TypeScript and Fluent UI components; the backend uses ASP.NET Core and MongoDB.
 
-## Quick overview

-- Framework: React 19 + TypeScript
+
+
+---
+
+## Quick overview ✅
+
+- Frontend: React 19 + TypeScript
 - Bundler / dev server: Vite
-- UI components: Fluent UI React (@fluentui/react-components)
+- UI library: Fluent UI React (`@fluentui/react-components`)
+- HTTP client: Axios
+- Forms: react-hook-form
+
+---
+
+## Requirements 💡
+
+- Node.js 24 
+- Yarn 
+- .NET 9.0 SDK (if you want to run the backend)
+- MongoDB (for running the backend locally or use a hosted cluster)
+
+---
+
+## Frontend — Quick start (yarn) 🔧
+
+1. Install dependencies:
+
+```bash
+yarn install
+```
+
+2. Create a `.env` in the frontend root if you need to override the API base URL (optional):
+
+```
+VITE_API_BASE_URL=http://localhost:5158
+```
+
+3. Start the dev server:
+
+```bash
+yarn dev
+```
+
+4. Useful scripts (from `package.json`):
+
+- `yarn dev` — start Vite dev server
+- `yarn build` — build production bundle
+- `yarn preview` — preview production build locally
+- `yarn lint` — run ESLint
+
+The app runs by default at `http://localhost:5173` when `yarn dev` is used.

+- Follow existing code patterns (Fluent UI `makeStyles`, service API modules, strict TypeScript).
+- Open an issue or submit a PR for features or bug fixes.

+If you'd like, I can also add more detailed setup for testing, a Docker compose file for local DB, or example environment files. Let me know which you'd prefer next. ✅
