 Add this line to your application's Gemfile:
 
 ```ruby
-gem 'lnrpc', '~> 0.7.0'
+gem 'lnrpc', '~> 0.15.5'
 ```
 lnrpc follows the lnd versioning, thus it is recommended to specify the exact version you need for your lnd node as dependency (see [#Versioning](#Versioning)).

 ### Client wrapper
 
+NOTE: v10.0 has breaking changes!

 An optional client wrapper ([Lnrpc::Client](https://github.com/bumi/lnrpc/blob/master/lib/lnrpc/client.rb)) makes
 initializing the gRPC client easier and removes the need for some boilerplate code for calling RPC methods.
 
 #### Example
