+## Application Configuration
+
+The application node's configuration must be extended so the oracle configuration can be read into the node through `app.toml`.
+
+The application should contain a custom configuration struct with a `"github.com/cosmos/cosmos-sdk/server/config"` embedded.
+
+Note: application function and type names may vary. The names in the following steps are arbitrary for example purposes only.
+
+```go config.go
+// CustomAppConfig defines the configuration for the app.
+type CustomAppConfig struct {
+	serverconfig.Config
+	// ... other configurations
+	Oracle oracleconfig.AppConfig `mapstructure:"oracle" json:"oracle"`
+}
+```
+
+Next, append the Oracle's default config template to the custom application template.
+
+```go config.go
+func CustomConfigTemplate() string {
+	return serverconfig.DefaultConfigTemplate + oracleconfig.DefaultConfigTemplate
+}
+```
+
+Finally, add a default configuration.
+
+```go config.go
+func DefaultConfig() (string, CustomAppConfig) {
+	serverConfig := serverconfig.DefaultConfig()
+    // edit serverConfig as needed
+
+	oracleCfg := oracleconfig.AppConfig{
+		Enabled:        true,
+		OracleAddress:  "localhost:8080",
+		ClientTimeout:  time.Second * 2,
+		MetricsEnabled: true,
+	}
+	customConfig := CustomAppConfig{
+		Config: *serverConfig,
+		Oracle: oracleCfg,
+	}
+
+	return CustomConfigTemplate(), customConfig
+}
+```
+
+The template and default configuration should be passed into `server.InterceptConfigsPreRunHandler` in the application's root command.
+
+Example:
+
+```go root.go
+package cmd
+
+import (
+	// ...
+	"github.com/cosmos/cosmos-sdk/server"
+)
+func NewRootCmd() *cobra.Command {
+	// ....
+
+    customAppTemplate, customAppConfig := DefaultConfig() // call function from previous step
+    return server.InterceptConfigsPreRunHandler(cmd, customAppTemplate, customAppConfig, cometConfig)
+}
+```

 ## Keepers
