 # @solana/rpc-spec-types
 
-TODO
+This package contains core types that can be used on both RPC and RPC Subscriptions specifications. It can be used standalone, but it is also exported as part of the Solana JavaScript SDK [`@solana/web3.js@rc`](https://github.com/solana-labs/solana-web3.js/tree/master/packages/library).
+
+## Types
+
+### `RpcRequest`
+
+An object that describes the elements of an RPC or RPC Subscriptions request. It consists of the following properties:
+
+-   `methodName`: The name of the RPC method or subscription requested.
+-   `params`: The parameters to be passed to the RPC server.
+
+### `RpcRequestTransformer`
+
+A function that accepts an `RpcRequest` and returns another `RpcRequest`. This allows the `RpcApi` to transform the request before it is sent to the RPC server.
+
+### `RpcResponse`
+
+A type that represents the response from an RPC server. This could be any sort of data which is why `RpcResponse` defaults to `unknown`. You may use a type parameter to specify the shape of the response — e.g. `RpcResponse<{ result: number }>`.
+
+### `RpcResponseTransformer`
+
+A function that accepts an `RpcResponse` and returns another `RpcResponse`. This allows the `RpcApi` to transform the response before it is returned to the caller.

 An object that exposes all of the functions described by `TRpcMethods`, and fulfils them using `TRpcTransport`. Calling each method returns a `PendingRpcRequest<TResponse>` where `TResponse` is that method's response type.
 
-### `RpcRequest`
-
-An object that describes the elements of a JSON RPC request. It consists of the following properties:
-
--   `methodName`: The name of the JSON RPC method to be called.
--   `params`: The parameters to be passed to the JSON RPC method.

-A function that accepts an `RpcRequest` and returns another `RpcRequest`. This allows the `RpcApi` to transform the request before it is sent to the JSON RPC server.

 ### `RpcApi<TRpcMethods>`
 
 For each of `TRpcMethods` this object exposes a method with the same name that maps between its input arguments and a `RpcApiRequestPlan<TResponse>` that describes how to prepare a JSON RPC request to fetch `TResponse`.
