+<h1 style="text-align: center">Distance Calculator</h1>
+This is a distance calculator made using Python. It can calculate the distance between two points on a 2D plane.
+
+## How to use
+
+`python3 distance_calculator.py`
+
+There are two functions, `main()` and `calculate_distance()`
+
+By default, if you run the project it runs the `main()` function.
+You can download the file to use it as a module.
+
+## Other
+
+I am planning to make a PyPI package of it soon.
+
+You can view it's repository [here](https://github.com/Mathdallas-code/Distance-Calculator)

+# Uses the pythagorean theorem to calculate the distance between two points on a 2D plane.
+# The points are represented as tuples of two numbers.
+# The function should return a float.
+
+# Sample :- startX = 0, startY = 0, endX = 3, endY = 4. 
+# So, according to pythagorean theorem, the distance between these two points is 5.0.
+
+# Hope this helps!
