 # CHANGELOG
 
+## v0.7.0 - _TBD_
+
+    * Updated legerco packages. Removed node-hid package as a dependency and make it an optional dependency. It is still used in integration tests but is causing problems for users on Linux distros. (#437)
+
 ## v0.6.0 - _March 4, 2018_
 
     * Move web3 types from being a devDep to a dep since one cannot use this package without it (#429)

 A subprovider that enables your dApp to send signing requests to a user's Ledger Nano S hardware wallet. These can be requests to sign transactions or messages.
 
+Ledger Nano (and this library) by default uses a derivation path of `44'/60'/0'`. This is different to TestRPC which by default uses `m/44'/60'/0'/0`. This is a configuration option in the Ledger Subprovider package.
+
+##### Ledger Nano S + Node-hid (usb)
+
+By default, node-hid transport support is an optional dependency. This is due to the requirement of native usb developer packages on the host system. If these aren't installed the entire `npm install` fails. We also no longer export node-hid transport client factories. To re-create this see our integration tests or follow the example below:
+
+```typescript
+import Eth from '@ledgerhq/hw-app-eth';
+import TransportNodeHid from '@ledgerhq/hw-transport-node-hid';
+async function ledgerEthereumNodeJsClientFactoryAsync(): Promise<LedgerEthereumClient> {
+    const ledgerConnection = await TransportNodeHid.create();
+    const ledgerEthClient = new Eth(ledgerConnection);
+    return ledgerEthClient;
+}
+
+// Create a LedgerSubprovider with the node-hid transport
+ledgerSubprovider = new LedgerSubprovider({
+    networkId,
+    ledgerEthereumClientFactoryAsync: ledgerEthereumNodeJsClientFactoryAsync,
+});
+```
+
 #### Redundant RPC subprovider
 
 A subprovider which attempts to send an RPC call to a list of RPC endpoints sequentially, until one of them returns a successful response.
