	  <h1>Raster image to PCB converter</h1>
	  <p>
	  Gerbolyze is a tool for rendering black and white raster (PNG) images directly onto gerber layers. You can
	  use this to put art on a PCB's silkscreen, solder mask or copper layers. The input is a black-and-white PNG
	  image that is vectorized and rendered into an existing gerber file. Gerbolyze works with gerber files
	  produced with any EDA toolchain and has been tested to work with both Altium and KiCAD.

	      Note that you will have to convert grayscale images into binary images yourself. Gerbolyze can't do this
	      for you since there are lots of variables involved. Our <a href="https://github.com/jaseg/gerbolyze/blob/master/README.rst#image-preprocessing-guide">Guideline on image processing</a> gives an overview on
	      <i>one</i> way to produce agreeable binary images from grayscale source material.
