+# TDDFizz
+
+Implementation of FizzBuzz with TDD and pytest.
+
+### Prerequisites
+
+The one and only, **pytest**!
+
+## Running the tests
+
+Simply get into the project directory and type:
+
+```
+pytest
+```
+
+## Author
+
+* **Dante Septem** - *The one who did everything...! Except pytest and Python of course! Oh and the english language and PyCharm, I didn't make those.*
+
+## Acknowledgments
+
+* pytest for being so awesome and better than the alternatives!
+* clamytoe from PyBites slack, for his feedback, thanks pal!
+* The PyBites folks, for the motivation and their awesome blog!
