+### Removing a feature flag locally (in development)
+
+When manually enabling or disabling a feature flag from the Rails console, its default value gets overwritten. 
+This can cause confusion when changing the flag's `default_enabled` attribute.
+
+To reset the feature flag to the default status, you can remove it in the rails console (`rails c`) 
+as follows:
+
+```ruby
+Feature.remove(:feature_flag_name)
+```
