 ## Flag evaluation
 
@@ -16,27 +14,27 @@ The module `schema.v1` contains a single `Service`, describing the 5 core `rpcs`
 response objects (`ResolveXXXRequest` and `ResolveXXXResponse`). The final `rpc` on the `Service` is a streamed response
 named `EventStream`, this is used to pass internal events to the client, such as `configuration_change` and `provider_ready`.

-a supported plugin for generating connect stubs then it is recommended to use these over grpc.

 ## Flag sync
 
 The module `sync.v1` is a service definition to provide flagd with feature flag configurations.
 The server exposes 2 `rpcs`.
 
 ### SyncFlags
+
 Flagd acts as the client and initiates the streaming with `SyncFlagsRequest`.
-The server implementation will then stream feature flag configurations through `SyncFlagsResponse`. The response contains
-`SyncState` which can be utilized to provide flagd with flexible configuration updates.

+The response contains `SyncState` which can be utilized to provide flagd with flexible configuration updates.
 
 ### FetchAllFlags
+
 Flagd acts as the client and sends the empty message `FetchAllFlagsRequest`.
 The server implementation responds with the full feature flag configuration through the `FetchAllFlagsResponse`.
 This `rpc` is used to re-sync flagd's internal state during configuration merge events.
 
 ## Code generation
 
-Easiest way to generate grpc code for your language of choice is using provided [buf](https://buf.build/) templates.
-For example, with required binaries in your path, java code generation can be done using 
-`buf generate --template buf.gen.java.yaml` command.
