+# libmd1200
+
+Python library for the MD1200 disk shelf, `VERY WIP` but in rapid development
+
+## Requirements (Software)
+ - pyserial
+
+## Requirements (Hardware)
+ - MD1200
+ - Serial connection
+
+## Usage
+Simply construct a `MD1200` object with the path to the serial device like
+
+```python
+from libmd1200 import MD1200
+SERIAL_DEVICE = "/dev/ttyUSB0"
+
+md1200 = MD1200(SERIAL_DEVICE)
+```
+
+From there the following funcitons have been implemented
+ - MD1200.get_temps()
+   - Returns a Temperature object
+ - MD1200.set_speed(SPEED)
+   - Sends the `_shutup` command with the fan speed in percentage
+ - MD1200.get_commands(INCLUDE_SUPERS)
+   - Gets all the available commands from the MD1200 disk shelf, INCLUDE_SUPERS is a bool that includes administrative and debug commands
