+`provider-opentelekomcloud` is a [Crossplane](https://crossplane.io/) provider that is built using [Upjet](https://github.com/crossplane/upjet) code generation tools and exposes XRM-conformant managed resources for the opentelekomcloud API.
+
+## 🚨 **Note: This project is still under development and is not recommended for use in production environments.** 🚨
 
 ## Getting Started
 
-Install the provider by using the following command after changing the image tag
-to the [latest release](https://marketplace.upbound.io/providers/opentelekomcloud/provider-opentelekomcloud):
+### Install provider-opentelekomcloud
+
+#### Install Crossplane
+
+Before you begin, make sure you have the following tools installed:
+- [kubectl](https://kubernetes.io/docs/reference/kubectl/kubectl/)
+- [helm](https://helm.sh/docs/intro/install/)
+- [up](https://github.com/upbound/up)
+
+Start by creating a namespace for Crossplane:
+
+```console
+kubectl create namespace crossplane-system
 ```
-up ctp provider install opentelekomcloud/provider-opentelekomcloud:v0.1.0
+
+Next, add the Crossplane Helm repository and update it:
+
+```console
+helm repo add crossplane-stable https://charts.crossplane.io/stable
+helm repo update
 ```
 
-Alternatively, you can use declarative installation:
+Finally, install Crossplane using Helm:
+
+```console
+helm install crossplane --namespace crossplane-system crossplane-stable/crossplane 
 ```
+
+After installation, verify that Crossplane is running correctly:
+
+```console
+helm list -n crossplane-system
+```
+
+```console
+kubectl get all -n crossplane-system
+```
+
+#### Install the Provider
+
+Install the provider by using the following command after changing the image tag to the [latest release](https://marketplace.upbound.io/providers/opentelekomcloud/provider-opentelekomcloud):
+
+```console
+up ctp provider install opentelekomcloud/provider-opentelekomcloud:v0.3.0
+```
+
+Alternatively, you can use declarative installation:
+
+```console
 cat <<EOF | kubectl apply -f -
 apiVersion: pkg.crossplane.io/v1
 kind: Provider
 metadata:
   name: provider-opentelekomcloud
 spec:
-  package: xpkg.upbound.io/opentelekomcloud/provider-opentelekomcloud:v0.1.0
+  package: xpkg.upbound.io/opentelekomcloud/provider-opentelekomcloud:v0.3.0
 EOF
 ```
 
-Notice that in this example Provider resource is referencing ControllerConfig with debug enabled.

+### Configure provider-opentelekomcloud
+
+ProviderConfig setup with secret:
+
+```console
+cat <<EOF | kubectl apply -f -
+apiVersion: v1
+kind: Secret
+metadata:
+  name: provider-opentelekomcloud-creds
+  namespace: crossplane-system

+```
+
+#### Running provider in debug mode
+
+To enable debug mode, create the following ControllerConfig and reference it in your Provider resource:
+
+```console
+cat <<EOF | kubectl apply -f -
+apiVersion: pkg.crossplane.io/v1alpha1
+kind: ControllerConfig
+metadata:
+  name: debug-config
+spec:
+  args:
+    - --debug
