+# Usage
+
+The gitops templates are built into one ocm component which is called `gitops-templates`.
+
+You can fetch it from the ocm repo: `ghcr.io/openmcp-project/components`.
+The component name is: `github.com/openmcp-project/gitops-templates`.
+
+To get a list of all resources, run the ocm cli:
+
+```bash
+> ocm get resources --repo OCIRegistry::ghcr.io/openmcp-project/components github.com/openmcp-project/gitops-templates:0.0.1
+
+NAME             VERSION IDENTITY TYPE       RELATION
+fluxcd           v0.0.1           fileSystem local
+gitops-templates v0.0.1           blob       external
+openmcp          v0.0.1           fileSystem local
+openmcp-operator v0.0.1           ociImage   local
+```
+
+The templates itself are fileSystem types. You can fetch these using:
+
+```bash
+# Just openmcp
+> ocm download resources --downloader ocm/dirtree --repo OCIRegistry::ghcr.io/openmcp-project/components github.com/openmcp-project/gitops-templates:v0.0.1 openmcp
+
+# Openmcp and fluxcd
+> ocm download resources --downloader ocm/dirtree --repo OCIRegistry::ghcr.io/openmcp-project/components github.com/openmcp-project/gitops-templates:v0.0.1 openmcp fluxcd
+```
+
+If you specify multiple templates, they will be put into a directory structure in the directory you are currently in:
+
+```txt
+github.com/
+  openmcp-project/
+    gitops-templates/
+      v0.0.1/
+        openmcp/
+        fluxcd/
+```
+
+## Rendering a template
+
+To render a template you can use helm, but you can also use our bootstrapper cli.
+
+To use helm first create a values.yaml:
+
+```yaml
+# values.yaml
+openmcpOperator:
+    image: ghcr.io/openmcp-project/images/openmcp-operator
+    tag: v0.9.1
+
+platformClusterKubeconfigSecretName: "platform-kubeconfig"
+```
+
+```bash
+> helm template --output-dir output --values values.yaml github.com/openmcp-project/gitops-templates/v0.0.1/openmcp
+```
