 # KiCAD_BOM_Generator
 
+## Description
+This BOM Generation Script takes KiCAD sch xml file and generate BOM in the following formats and rules:
+
+1. Parts are not included if any of the following fields are checked:
+    - DNP
+    - excluded from BOM
+2. Parts are Grouped by:
+    - Value
+    - Footprint
+    - MFR_PN
+    - MFR_ALT
+3. Parts are sorted by: Ref
+4. Output Fields: Ref, Value, MFR_PN, MFR_PN_ALT, Qnty, LibPart, Footprint, Comment
+
+## Instructions to Use this Script
+1. Set `PYTHONPATH` to include the path to the `kicad_netlist_reader` scripts inside KiCad Installation
+    - Located at `{KiCAD Installation PATH}/share/kicad/plugins`
+2. Generate the XML file from KiCad Schematics
+3. Run `python -m generate_bom_from_xml input.xml output.csv`
