 ### Footprints

+The PyPPM project uses the [gEDA PCB](http://pcb.geda-project.org/) design
 tool for all printed circuit boards. While the gEDA footprint library is
 fairly extensive, a few custom device footprints had to be made to suit
 the more exotic/modern parts that went into PyPPM boards.
 
 ### Models
 
-The `models` directory holds all SPICE models used by simulations of PyPPM
-circuit behavior. To see the actual simulation files, look in `simulations`.

 ### Notes
 
-The `notes` directory holds a few random jots of information that don't really
-fit into any of the other subdirectories, like recommended color schemes for
-Gerber rendering, _etc_. Documentation related to the PyPPM's entry into The
-Hackaday Prize will also be placed here.
