 ## What Flux does
 
 Flux is most useful when used as a deployment tool at the end of a
 Continuous Delivery pipeline. Flux will make sure that your new
 container images and config changes are propagated to the cluster.
 
-### Features
-
-Its major features are:
-
-- [Automated git → cluster synchronisation](/docs/introduction.md#automated-git-cluster-synchronisation)
-- [Automated deployment of new container images](/docs/introduction.md#automated-deployment-of-new-container-images)
-- [Integrations with other devops tools](/docs/introduction.md#integrations-with-other-devops-tools) ([Helm](/docs/references/helm-operator-integration.md) and more)
-- No additional service or infrastructure needed - Flux lives inside your
-  cluster
-- Straight-forward control over the state of deployments in the
-  cluster (rollbacks, lock a specific version of a workload, manual
-  deployments)
-- Observability: git commits are an audit trail, and you can record events that
-  occured, for example: why a given deployment was locked.
