 ## Summary
 
 WireViz is a tool for easily documenting cables, wiring harnesses and connector pinouts. It takes plain text, YAML-formatted files as input and produces beautiful graphical output (SVG, PNG, ...) thanks to [GraphViz](https://www.graphviz.org/). It handles automatic BOM (Bill of Materials) creation and has a lot of extra features.
