+# Base-N Calculator
+
+It is a GUI based script that allows user to enter a number of any base and convert it to another. However, there is a small limitation for the conversion.
+
+* The base should not be smaller than 2.
+* Alphabetic symbols are not used in conversions, you'll have to convert this part by yourself. To know why check this [link](https://www.mathsisfun.com/numbers/bases.html)
+
+# Installation
+
+Nothing to be installed, just run the script directly.
+
+# Usage
+
+1) Fill the required fields.
+2) the conversion result will be displayed in the Result Entry.
+
+# Output
+
+Converted number to base Y.
