 ## Supported platforms
 
-We use the
+This library works with Node.js as well as certain browsers. We use the
 [@ledgerhq/hw-transport-webusb](https://github.com/LedgerHQ/ledgerjs/tree/master/packages/hw-transport-webusb)
 library to connect to Ledger devices from the browser via USB. You can check the
 support status of this library
 [here](https://github.com/LedgerHQ/ledgerjs/tree/master/packages/hw-transport-webusb#support-status).
 
+Note the optional dependencies:
+
+```json
+"optionalDependencies": {
+  "@ledgerhq/hw-transport-node-hid": "^5.23.2",
+  "@ledgerhq/hw-transport-webusb": "^5.23.0"
+}
+```
+
+If you are using this library with Node.js you must install
+`@ledgerhq/hw-transport-node-hid`. You’ll need `@ledgerhq/hw-transport-webusb`
+for the browser.
+
 ## Running the demo
 
+### Node.js
+
+Connect the Ledger device via USB, open the Cosmos app, then run the demo (this
+will also build the package):
+
+```sh
+yarn demo-node
+```
+
+### Browser
+
 Build the package for web:
 
 ```sh
