+### Dash Button Preparation
+
+Follow Amazon's instructions to configure your button to send messages when you push them but not actually order anything. When you get a Dash button, Amazon gives you a list of setup instructions to get going. Just follow this list of instructions, but don’t complete the final step of selecting a product to order. **Do not select a product, just exit the app**.
+
+## Configuration
+
+1. Discover the Dash Buttons using `node node_modules/node-dash-button/bin/findbutton`.
+1. Rename `config-sample.json` to `config.json`.
