 # OffiTracker
 
 Ever wanted to make music in Excel? Now you can!
+
+OffiTracker lets you use CSV spreadsheets to create chiptunes. Its as simple as typing in the frequency, pulse width and duration.
+

+![The softwares CLI](img/cli.png)
+
+## Usage
+
+Running OffiTracker requires the following packages to be present on your system:
+
+`python3, python3-csv, pyhon3-numpy, python3-sounddevice`
+
+Assuming `python3` is already installed, you can use the following command to install the dependencies:
+
+```bash
+pip3 install csv numpy sounddevice
+```
+
+After that, simply run `python3 offitracker.py` and enjoy.
+
+
+
+____
+
+Examples can be found in the `example` folder.
+
+For usage information, check the contents of the `offitracker.py` file
