+## Creating feature flags in development
+
+The process for creating a feature flag is the same as [enabling a feature flag in development](https://docs.gitlab.com/ee/development/feature_flags.html#enabling-a-feature-flag-in-development).
+
+Your feature flag can now be:
+
+- [made available to the frontend](https://docs.gitlab.com/ee/development/feature_flags.html#frontend) via the `gon`
+- queried in [tests](https://docs.gitlab.com/ee/development/feature_flags.html#specs)
+- queried in HAML templates and ruby files via the `Feature.enabled?(:my_shiny_new_feature_flag)` method
