+Gerbolyze high-resolution image-to-PCB converter
+================================================
+
+Tooling for PCB art is quite limited in both open source and closed source ecosystems. Something as simple as putting a
+pretty picture on a PCB can be an extremely tedious task. Depending on the PCB tool used, various arcane incantations
+may be necessary and even modestly complex images will slow down most PCB tools to a crawl.
+
+Gerbolyze solves this problem in a toolchain-agnostic way by directly vectorizing bitmap files onto existing gerber
+layers. Gerbolyze has been tested against both the leading open-source KiCAD toolchain and the industry-standard Altium
+Designer.
+
+Produce high-quality artistic PCBs in three easy steps!
+-------------------------------------------------------
+
+Gerbolyze works in three steps.
+
+1. Generate a scale-accurate preview of the finished PCB from your CAD tool's gerber output:
+   
+   .. code::
+        
+       $ gerbolyze render top my_gerber_dir preview.png
+
+2. Load the resulting preview image into the gimp or another image editing program. Use it as a guide to position scale your artwork. Create a black-and-white image from your scaled artwork using GIMP's newsprint filter. Make sure most details are larger than about 10px to ensure manufacturing goes smooth.
+
+3. Vectorize the resulting grayscale image drectly into the PCB's gerber files:
+
+   .. code::
+
+        $ gerbolyze vectorize top input_gerber_dir output_gerber_dir black_and_white_artwork.png
