 # KiBoM
 Configurable BoM generation tool for KiCad EDA (http://kicad-pcb.org/)
+
+## Description
+
+KiBoM is a configurable BOM (Bill of Materials) generation tool for KiCad EDA. Written in Python, it can be used directly with KiCad software without the need for any external libraries or plugins. 
+
+KiBoM intelligently groups components based on multiple factors, and can generate BoM files in multiple output formats.
+
+BoM options are user-configurable in a per-project configuration file.
+
+## Features
+
+### Intelligent Component Grouping
+
+To be useful for ordering components, the BoM output from a KiCad project should be organized into sensible component groups. KiBom groups components based on the following factors:
+
+- Part name: (e.g. 'R' for resistors, 'C' for capacitors, or longer part names such as 'MAX232')
+
+*note: parts such as {'R','r_small'} can also be grouped together*
+
+- Footprint: Compoments must have the same footprint to be grouped together
+
+- Value: Components must have the same value to be grouped together 
+
+### Intelligent Value Matching
+
+Some component values can be expressed in multiple ways (e.g. "0.1uF" === "100n" for a capacitor). KiBoM matches value strings based on their interpreted numerical value, such that components are grouped together even if their values are expressed differenly.
+
+### Field Extraction
+
+In addition to the default KiCad fields which are assigned to each component, KiBoM extracts and custom fields added to the various components. 
+
+**Default Fields**
+The following default fields are extracted and can be added to the output BoM file:
+* Description - Part description as per the schematic symbol
+* References - List of part references included in a particular group
+* Quantity - Number of components included in a particular group
+* Part - Part name as per the schematic symbol
+* Part Lib - Part library for the symbol **(default - not output to BoM file)**
+* Footprint - Part footprint
+* Footprint Lib - Part footprint library **(default - not output to BoM file)**
+* Datasheet - Component datasheet extracted either from user-included data, or from part library
+
+**User Fields**
+If any components have custom fields added, these are available to the output BoM file.
+
+### Multiple File Outputs
+Multiple BoM output formats are supported:
+* CSV (Comma separated values)
+* TSV (Tab separated values)
+* TXT (Text file output with tab separated values)
+* XML
+* HTML
