+A minimalist Python application which solves a given Sudoku problem in a *.csv file* following certain *formatting rules*.
 
 ### Formatting rules for .txt Sudokus
+- The **first row** of the *.csv file* must be the following: `a,b,c,d,e,f,g,h`.
+- The following rows will be the **numbers** of the sudoku given. The number **zero (0)** represents an empty cell or *naked cell*.

+- **Pandas**
+
+To be able to run this project, execute: `pip install -r requirements.txt`
+
 ## Steps To Execution
 
-## Samples
