 # Build of Materials
-We recommend using Octopart's [BOM tool](https://octopart.com/bom-tool/) and import the [BOM.csv](BOM.csv).
+This is a list of components you need to build the OpenTendo NES. You will need some components from the original NES and have to order more modern components.
+
+## From the OEM NES
+| Reference | Qty | Part | Description |
+| --------- | :-: | ---- | ----------- |
+| U5 | 1 | RP2C02 | PPU |
+| U6 | 1 | RP2A03 | CPU |
+| P2 | 1 | Connector | 48 pin expansion port |
+| P6 | 1 | Connector | 5 pin connector for the power/reset breakout board |
+
+### Alternatives

+| P2 | 2 | [PPPC241LFBN-RC](https://octopart.com/pppc241lfbn-rc-sullins-271073)<sup>[1]</sup> | 24 Pins Header Connector 0.100" (2.54mm) Through Hole |
+
+> [!NOTE]
+> <sup>[1]</sup> If you don't want to use the OEM expansion port, you can replace it with a header pin connector or not put anything at all. OpenTendo should still work without the expansion port. 
+
+## What to buy
+We recommend using Octopart's [BOM tool](https://octopart.com/bom-tool/) and import the [BOM.csv](BOM.csv). This tool makes ordering from multiple Octopart's authorized distributors (Digikey, Mouser, etc.) easier.
