-# ZPPR
+# ZPPR 
 
+The applcation allows its users to control their mouse cursor using their hands BUT without a physical mouse. 
+
+Haar cascades aren't an effect of my work. Their owner is GitHub user [trane293](https://github.com/trane293).
+[Here](https://github.com/trane293/Palm-Fist-Gesture-Recognition/)'s the link to his project I used.
+
+To run the project you have to install the following python3 libraries: 
+- opencv-python
+- numpy
+- mouse
+
+You can do it using `pip3`
+e.g. `pip3 install opencv-python`
+
+To run the application simply run 
+
+`python3 main.py` 
+
+from the app directory.
+
+Tutorials and other materials used during development:
