 The protobuf generator uses the same annotations as [grpc-gateway](https://github.com/grpc-ecosystem/grpc-gateway). This also gives you the benefit of being able to generate Swagger files by using protoc.
 
 ## Installation
 
-First, download `protoc-gen-rails` from the releases page on the right. Ensure it's somewhere in your PATH.

+### Hooking up Callbacks
+
+If you're using [gruf](https://github.com/bigcommerce/gruf), as long as your Gruf controllers are loaded on application load, you don't have to do anything else - grpc-rest will automatically hook the callbacks up. If you're not, you have to tell GrpcRest about your server. An example might look like this:
+
+```ruby
+# grpc_setup.rb, a shared library file somewhere in the app
+
+def grpc_server
+  s = GRPC::RpcServer.new
+  s.handle(MyImpl.new) # handler inheriting from your service class - see https://grpc.io/docs/languages/ruby/basics/
+  s
+end
+
+# startup script for gRPC
+
+require "grpc_setup"
+server = grpc_server
+server.run_till_terminated_or_interrupted([1, 'int', 'SIGQUIT'])
+
+# Rails initializer
+require "grpc_setup"
+server = grpc_server
+GrpcRest.register_server(server)
+```
+
+## To Do
+
+* Support repeated fields via comma-separation (matches grpc-gateway, but is it really useful?)
+* Install via homebrew and/or have the binary in the gem itself
