 A process could connect to an `rmb-relay` using a direct client.\
 To create a new direct client instance, a process needs to have:
 
-- A valid mnemonics, with an activated account on the TFChain.
+- A valid private key, with an activated account on the Registrar.
 - The key type of these mnemonics.
 - A relay URL that the direct client will connect to.
 - A session id. This could be anything, but a twin must only have a unique session id per connection.
 - A substrate connection.
-
-#### **Example**
-
-Creating a new direct client instance:
-
-```Go
-subManager := substrate.NewManager("wss://tfchain.dev.grid.tf/ws")
-sub, err := subManager.Substrate()
-if err != nil {
-    return fmt.Errorf("failed to connect to substrate: %w", err)
-}
-
-defer sub.Close()
-client, err := direct.NewRpcClient(direct.KeyTypeSr25519, mnemonics, "wss://relay.dev.grid.tf", "test-client", sub, false)
-if err != nil {
-    return fmt.Errorf("failed to create direct client: %w", err)
-}
-```
-
-Assuming there is a remote calculator process that could add two integers, an rmb call using the direct client would look like this:
-
-```Go
-x := 1
-y := 2
-var sum int
-err := client.Call(ctx, destinationTwinID, "calculator.add", []int{x, y}, &sum)
-```
