+
+```ruby
+# config/initializers/turbo_boost_commands.rb
+TurboBoost::Commands.config.tap do |config|
+  # opt-[in/out] of alerting on abort (true, *false, "development", "test", "production")
+  config.alert_on_abort = false
+
+  # opt-[in/out] of alerting on error (true, *false, "development", "test", "production")
+  config.alert_on_error = false
+
+  # opt-[in/out] of including precompiling TurboBoost assets (*true, false)
+  config.precompile_assets = true
+
+  # opt-[in/out] of forgery protection (true, *false)
+  config.protect_from_forgery = true
+
+  # opt-[in/out] of raising an error when an invalid command is invoked (true, false, *"development", "test", "production")
+  config.raise_on_invalid_command = "development"
+
+  # opt-[in/out] of state resolution (true, *false)
