 # UTxO RPC
 
-This package contains the generated code from [the UTxO RPC specification](https://utxorpc.org/). Codegen was performed using `proto-lens-protoc` and contains `Message` types useful for serde.
+This package is generated by `proto-lens-protoc` from the [u5c specification](https://utxorpc.org) and contains `Data.ProtoLens.Message.Message` instances useful for serde. It is designed to be used with the [client](https://hackage.haskell.org/package/utxorpc-client) or [server](https://hackage.haskell.org/package/utxorpc-server) SDK. Build a message with the `lens` library by importing the relevant `utxorpc` modules and calling `Data.ProtoLens.Message.defMessage`:
 
-Users: For more support for implementing a UTxO RPC client or service, see [the SDK](https://www.github.com/utxorpc/haskell-sdk).
+```haskell
+import Control.Lens.Operators ((&), (.~))
+import Data.ProtoLens.Message (Message (defMessage))
+import qualified Data.Text.Encoding as T
+import Proto.Utxorpc.V1.Sync.Sync (FetchBlockRequest)
+import Proto.Utxorpc.V1.Sync.Sync_Fields (hash, index)
 
-Maintainers: See [the UTxO spec repo README](https://github.com/utxorpc/spec#readme).
+fetchBlockRequest :: FetchBlockRequest
+fetchBlockRequest =
+defMessage
+    & ref .~
+    [ defMessage 
+        & index .~ 116541970
+        & hash .~ T.encodeUtf8 "9d5abce5b1a7d94b141a597fd621a1ff9dcd46579ff1939664364311cd1be338"
+    ]
+```
+
+The easieset way to send requests or run a service is through the SDKs: [utxorpc-client](https://hackage.haskell.org/package/utxorpc-client) and [utxorpc-server](https://hackage.haskell.org/package/utxorpc-server).

+# Generating this package from the spec
+Please see the u5c project [README](https://github.com/utxorpc/spec#readme) for information on how this package was generated. To generate this code yourself, please see [`proto-lens`](https://github.com/google/proto-lens#readme).
+
+NOTE: `proto-lens-protobuf-types` version >= 0.7.2 is required to build this package, as it includes support of the `FieldMask` well-known type.

+description:    # The UTxO RPC Specification
+                [UTxO]((https://utxorpc.org/) RPC (u5c for short) is an interface tailored for interactions with UTxO-based blockchains, prioritizing performance and developer experience. By providing a common contract, a range of SDKs, and thorough documentation, UTxO RPC aims to facilitate:
 
                 * Reusability: Enabling shared components that can be reused across different projects to simplify the integration effort.
                 * Interoperability: A common interface to simplify integrations between different parties and avoid the common pitfall of vendor lock-in.
                 * Performance: A serialized binary format which is compact and efficient, resulting in smaller message sizes and reduced network overhead compared to its JSON counterpart
 
                 Please note that UTxO RPC is just a specification of an interface between agents and the blockchain, it doesn't provide any concrete client / provider implementations. The primary purpose of u5c is to define a set of standardized methods, data structures, and communication patterns.
