+# Flux OCM Component
+
+This directory contains the OCM (Open Component Model) packaging for [Flux](http://github.com/fluxcd/flux2)
+
+## Component structure
+
+```text
+flux/
+├── component-constructor.yaml  # OCM component descriptor
+├── values.yaml.tpl  # values.yaml template for ocm-kit
+```
+
+## Quick start
+
+### 1. Build the CTF archive
+
+Run from the `flux/` directory of this repo:
+
+```bash
+ocm add componentversion --version 0.1.0 --create --file ./ctf component-constructor.yaml
+```
+
+### 2. Transfer to a registry
+
+```bash
+# Public registry (replace with your org)
+ocm transfer ctf --copy-local-resources ./ctf ghcr.io/your-org
+
+# Local registry for testing
+ocm transfer ctf --copy-local-resources ./ctf localhost:5001
+```
+
+The `--copy-local-resources` flag rewrites the image references inside the
+component to point to the target registry.
