+# Wattif: Home Energy Improvement Simulator
 
-A tool that uses your current home energy data an simulates the impact of installing a home battery. It also does a cost analysis. 
+**Watt if?** is a simulation tool designed to help Flemish homeowners evaluate the impact of energy improvements such as batteries, heat pumps, solar panels, and air conditioning on their **energy bills** and **carbon emissions**. Currently, Wattif works exclusively with data from **Fluvius**, the Flemish energy distribution company.
 
-The tool works specifically for the flemish system with input data from fluvius and cost analysis based on the flemish energy pricing.

-## Used Tools
-This project makes use of the Radzen.blazer package for UI components.
+## How It Works
+
+1. **Upload Your Data**
+Download your electricity usage and gas usage from the mijn fluvius website and upload it to the tool.
+
+2. **Add Home Improvements**
+Add the improvements you want to make and configure them.
+
+3. **Simulate & Analyze**
+Press the simulate button and look at the new energy usage and carbon intensity of your house.
+
+4. **Enter Your Energy Contract**
+Fill out your current energy contract pricing details and the tool cacluates savings/losses.
