+# Budget Management System
+
+This project is a Budget Management System that fetches and caches budget-related data from an API. It organizes the data into various categories and handles rate limits to ensure smooth operation.
+
+## Project Structure
+
+## Setup
+
+1. **Set up environment variables:**
+
+	Create a `.env` file in the root directory and add your API token and budget ID:
+	```
+	API_TOKEN=your_api_token
+	BUDGET_ID=your_budget_id
+	```
+
