+# fucking-black-scholes model
+
+I'm a finance student trying to stop procrastinating and start studying my derivatives lectures. So, in order to
+understand the Black-Scholes model, I built this simple command line tool. Which is far more interesting than memorizing
+stupid stuff from the professor's slides.
+
+## Installation
+
+### Using PIP
+
+```bash
+pip install fucking-black-scholes
+```
+
+### Manual
+
+```bash
+git clone https://github.com/denniscm190/fucking-black-scholes.git
+cd fucking-black-scholes
+python setup.py install
+```
+
+## Usage
+
+```bash
+fbs --help
+```
+
+### Examples
+
+Price a European call option with the following data:
+- Spot price = $20
+- Exercise price = $21
+- Risk free rate = 5%
+- Standard deviation = 25%
+- Time to expiration = 6 months
+
+#### Command
+```bash
+fbs --spot-price=20.00 --exercise-price=21.00 --risk-free-rate=0.05 --std=0.25 --expiration=0.5
+```
+
+#### Output
+
+```bash
+---------------------------------------------
+European call option price: 1.197698084193286
+---------------------------------------------
+```
