-# bdf to numpy
+# .bdf to NumPy
 
+This project takes a .bdf file and turns it into a [NumPy](https://www.numpy.org/) Array with an intended use with LED matrix displays. My [LED Stock Ticker](https://gitlab.com/them-boys/raspberry-pi-stock-ticker) uses this package. A good list of .bdf files can be found [here](https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/fonts)
+
+## Usage
+
+```python
+import numpy as np
+import matplotlib.pyplot as plt
+
+font = parse_chars("9x18.bdf")
+matrix = font["A"]
+text = "nson"
+
+for letter in text:
+    matrix = np.concatenate((matrix, font[letter]), axis=1)
+
+plt.imshow(matrix)
+plt.show()
+```
+
+Which outputs:
