Feature flags in development of GitLab

Feature flags can be used to gradually roll out changes, be it a new feature, or a performance improvement. By using feature flags, we can comfortably measure the impact of our changes, while still being able to easily disable those changes, without having to revert an entire release.

Before using feature flags for GitLab's development, read through the following:

• Process for using features flags.
• Developing with feature flags.
• Controlling feature flags.

When documenting feature flags, see Feature flags in the Documentation Style Guide.
