 We want to pack all the letters into the square, using as little material as possible. If a single square is not enough, we also want to minimize the number of squares used.
 
-You may also know this as the bin packing problem and stock cutting problem.
+In the CNC world this is called "nesting", and [software](http://www.mynesting.com/) that [does this](http://www.autodesk.com/products/trunest/overview) is typically targeted at [industrial customers](http://www.hypertherm.com/en/Products/Automated_cutting/Nesting_software/) and [very expensive](http://www.nestfab.com/pricing/).

+SVGnest is a free and open-source alternative that solves this problem with a geometric approach, using a genetic algorithm for global optimization. It works for arbitrary containers and concave edge cases, and performs on-par with existing commercial software.

 ## Usage
 
 Make sure all parts have been converted to outlines, and that no outlines overlap. Upload the SVG file and select one of the outlines to be used as the bin.
