+## Building local binaries
+
+The Kyverno repository contains code for three different binaries:
+- [`kyvernopre`](#building-kyvernopre-locally):
+  Binary to update/cleanup existing resources in clusters. This is typically run as an init container before Kyverno controller starts.
+- [`kyverno`](#building-kyverno-locally):
+  The Kyverno controller binary.
+- [`cli`](#building-cli-locally):
+  The Kyverno command line interface.
+
+> **Note**: You can build all binaries at once by running `make build-all`.
