+## Installation
+
+```shell
+git clone https://github.com/kristoferssolo/Traffic-Light-Detector
+cd Traffic-Light-Detector
+pip install .
+```
+
+## Examples
+`./main.py` -- Creates necessary directories in `/assets/`
+`./main.py -i` -- Detects traffic lights and their signal color for all files located in `/assets/images_in/` and saves them in `/assets/images_out/`.
+`./main.py -c <int>` -- Uses webcam or any camera to detect traffic lights in real time.
+`./main.py -sc <int>` -- Plays sound file located in `/assets/sound/move.mp3` whenever green light signal is detected via camera.
+
+Replace `<int>` with your camera number specified by the operating system. Probably `0` or `1`, but can be higher.
+
