+# Reference implementation 
+
+This example creates a local version of the CNOE reference implementation.
+
+## Prerequisites
+
+Ensure you have the following tools installed on your computer.
+
+**Required**
+
+- [idpbuilder](https://github.com/cnoe-io/idpbuilder/releases/latest): version `0.3.0` or later
+- [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl): version `1.27` or later
+- Your computer should have at least 6 GB RAM allocated to Docker. If you are on Docker Desktop, see [this guide](https://docs.docker.com/desktop/settings/mac/).
+
+**Optional**
+
+- AWS credentials: Access Key and secret Key. If you want to create AWS resources in one of examples below.
+
+## Installation
+
+**_NOTE:_**
+- If you'd like to run this in your web browser through Codespaces, please follow [the instructions here](./codespaces.md) to install instead. 
+
+- _This example assumes that you run the reference implementation with the default port configguration of 8443 for the idpBuilder.
+If you happen to configure a different host or port for the idpBuilder, the manifests in the reference example need to be updated
+and be configured with the new host and port. you can use the [replace.sh](replace.sh) to change the port as desired prior to applying the manifest as instructed in the command above._
+
+Run the following command from the root of this repository.
+
+```bash
+idpbuilder create --use-path-routing --package-dir examples/ref-implementation
+```
+
+This will take ~6 minutes for everything to come up. To track the progress, you can go to the [ArgoCD UI](https://cnoe.localtest.me:8443/argocd/applications).
+
+### What was installed?
+
+1. **Argo Workflows** to enable workflow orchestrations.
+2. **Backstage** as the UI for software catalog and templating. Source is available [here](https://github.com/cnoe-io/backstage-app).
+3. **Crossplane**, AWS providers, and basic compositions for deploying cloud related resources (needs your credentials for this to work)
+4. **External Secrets** to generate secrets and coordinate secrets between applications.
+5. **Keycloak** as the identity provider for applications.
+6. **Spark Operator** to demonstrate an example Spark workload through Backstage.
+
+If you don't want to install a package above, you can remove the ArgoCD Application file corresponding to the package you want to remove.
+For example, if you want to remove Spark Operator, you can delete [this file](./spark-operator.yaml).
+
+```bash
+# remove spark operator from this installation.
+rm examples/ref-implementation/spark-operator.yaml
+```
+
+The only package that cannot be removed this way is Keycloak because other packages rely on it. 
+
+
+#### Accessing UIs
+- Argo CD: https://cnoe.localtest.me:8443/argocd
+- Argo Workflows: https://cnoe.localtest.me:8443/argo-workflows
+- Backstage: https://cnoe.localtest.me:8443/
+- Gitea: https://cnoe.localtest.me:8443/gitea
+- Keycloak: https://cnoe.localtest.me:8443/keycloak/admin/master/console/
+
+# Using it
+
+For this example, we will walk through a few demonstrations. Once applications are ready, go to the [backstage URL](https://cnoe.localtest.me:8443).
+
+Click on the Sign-In button, you will be asked to log into the Keycloak instance. There are two users set up in this 
+configuration, and their password can be retrieved with the following command:
+
+```bash
+idpbuilder get secrets
+```
+
+Use the username **`user1`** and the password value given by `USER_PASSWORD` field to login to the backstage instance.
+`user1` is an admin user who has access to everything in the cluster, while `user2` is a regular user with limited access.
+Both users use the same password retrieved above.
+
+If you want to create a new user or change existing users:
+
+1. Go to the [Keycloak UI](https://cnoe.localtest.me:8443/keycloak/admin/master/console/). 
+Login with the username `cnoe-admin`. Password is the `KEYCLOAK_ADMIN_PASSWORD` field from the command above. 
+2. Select `cnoe` from the realms drop down menu.
+3. Select users tab.
+
+
+## Basic Deployment
+
+Let's start by deploying a simple application to the cluster through Backstage.
+
+Click on the `Create...` button on the left, then select the `Create a Basic Deployment` template.
+
+![img.png](images/backstage-templates.png)
+
+
+In the next screen, type `demo` for the name field, then click Review, then Create. 
+Once steps run, click the Open In Catalog button to go to the entity page. 
+
+![img.png](images/basic-template-flow.png)
+
+In the demo entity page, you will notice a ArgoCD overview card associated with this entity. 
+You can click on the ArgoCD Application name to see more details.
+
+![img.png](images/demo-entity.png)
+
+### What just happened?
+
+1. Backstage created [a git repository](https://cnoe.localtest.me:8443/gitea/giteaAdmin/demo), then pushed templated contents to it.
+2. Backstage created [an ArgoCD Application](https://cnoe.localtest.me:8443/argocd/applications/argocd/demo?) and pointed it to the git repository.
+3. Backstage registered the application as [a component](https://cnoe.localtest.me:8443/gitea/giteaAdmin/demo/src/branch/main/catalog-info.yaml) in Backstage.
+4. ArgoCD deployed the manifests stored in the repo to the cluster.
+5. Backstage retrieved application health from ArgoCD API, then displayed it.
+
+![image.png](images/basic-deployment.png)
+
+
+## Argo Workflows and Spark Operator
+
+In this example, we will deploy a simple Apache Spark job through Argo Workflows.
+
+Click on the `Create...` button on the left, then select the `Basic Argo Workflow with a Spark Job` template.
+
+![img.png](images/backstage-templates-spark.png)
+
+Type `demo2` for the name field, then click create. You will notice that the Backstage templating steps are very similar to the basic example above.
+Click on the Open In Catalog button to go to the entity page.
+
+![img.png](images/demo2-entity.png)
+
+Deployment processes are the same as the first example. Instead of deploying a pod, we deployed a workflow to create a Spark job.
+
+In the entity page, there is a card for Argo Workflows, and it should say running or succeeded. 
+You can click the name in the card to go to the Argo Workflows UI to view more details about this workflow run. 
+When prompted to log in, click the login button under single sign on. Argo Workflows is configured to use SSO with Keycloak allowing you to login with the same credentials as Backstage login.
+
+Note that Argo Workflows are not usually deployed this way. This is just an example to show you how you can integrate workflows, backstage, and spark.
+
+Back in the entity page, you can view more details about Spark jobs by navigating to the Spark tab.
+
+## Application with cloud resources.
+
+Similar to the above, we can deploy an application with cloud resources using Backstage templates.
+In this example, we will create an application with a S3 Bucket.
+
+Choose a template named `App with S3 bucket`, type `demo3` as the name, then choose a region to create this bucket in.
+
+Once you click the create button, you will have a very similar setup as the basic example. 
+The only difference is we now have a resource for a S3 Bucket which is managed by Crossplane.
+
+Note that Bucket is **not** created because Crossplane doesn't have necessary credentials to do so.
+If you'd like it to actually create a bucket, update [the credentials secret file](crossplane-providers/provider-secret.yaml), then run `idpbuilder create --package-dir examples/ref-implementation`.
+
+In this example, we used Crossplane to provision resources, but you can use other cloud resource management tools such as Terraform instead. 
+Regardless of your tool choice, concepts are the same. We use Backstage as the templating mechanism and UI for users, then use Kubernetes API with GitOps to deploy resources. 
+
+## Notes
+
+- In these examples, we have used the pattern of creating a new repository for every app, then having ArgoCD deploy it.
+This is done for convenience and demonstration purposes only. There are alternative actions that you can use. 
+For example, you can create a PR to an existing repository, create a repository but not deploy them yet, etc.
+
+- If Backstage's pipelining and templating mechanisms is too simple, you can use more advanced workflow engines like Tekton or Argo Workflows. 
+  You can invoke them in Backstage templates, then track progress similar to how it was described above.

+## Running idpbuilder in Codespaces in Browser
+
+**_NOTE:_**: __Steps described below applies to running this implementation in Codespaces in **web browsers** (e.g. Firefox and Chrome).
+If you are using Codespaces with GitHub CLI, steps described here do not apply to you.__ 
+
+
+Let's create an instance of Codespaces.
+
+![img.png](images/codespaces-create.png)
+
+It may take a few minutes for it to be ready. Once it's ready, you can either get the latest release of idpbuilder or build from the main branch.
+Build the idpbuilder binary. 
+
+
+- Get the latest release:
+  ```bash
+  version=$(curl -Ls -o /dev/null -w %{url_effective} https://github.com/cnoe-io/idpbuilder/releases/latest)
+  version=${version##*/}
+  wget https://github.com/cnoe-io/idpbuilder/releases/download/${version}/idpbuilder-linux-amd64.tar.gz
+  tar xzf idpbuilder-linux-amd64.tar.gz
+  sudo mv ./idpbuilder /usr/local/bin/
+  ```
+- Alternatively, build from the main branch
+  ```bash
+  make build
+  sudo mv ./idpbuilder /usr/local/bin/
+  ```
+
+Codespaces assigns random hostname to your specific instance. You need to make sure they are reflected correctly.
+Instance host name is available as an environment variable (`CODESPACE_NAME`). Let's use it to setup our host names. 
+Run the following commands to update host name and ports. Port is set to 443 because this is the port used by the browser to access your instance.
+
+
+```bash
+cd examples/ref-implementation 
+
+./replace.sh ${CODESPACE_NAME}-8080.${GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN} 443
+
+cd - 
+```
+
+Now you are ready to run idpbuilder with reference implementation.
+
+```bash
+idpbuilder create --protocol http  \
+  --host ${CODESPACE_NAME}-8080.${GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN} \
+  --port 8080 --use-path-routing --package-dir examples/ref-implementation
+```
+Once idpbuilder finishes bootstrapping, you should have port 8080 forward in the port tab within Codespaces.
+
+![](images/port.png)
+
+You may get a 404 page after clicking the port 8080 forwarded address. This is completely normal because Backstage may not be ready yet. 
+Give it a few more minutes and it should redirect you to a Backstage page.
+
+### Accessing UIs
+
+If you'd like to track progress of deployment, go to `/argocd` path and login with your ArgoCD credentials. 
+For example run this command to get the URL for Argo CD:
+```bash
+echo https://${CODESPACE_NAME}-8080.${GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN}/argocd
+```
+
+From here on, you can follow the instructions in the [README](./README.md) file. The only difference is that the URL to access UIs is given by:
+
+```echo
+echo https://${CODESPACE_NAME}-8080.${GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN}
+```
+
+For example, if you need to access Argo Workflows UI, instead of going to `https://cnoe.localtest.me:8443/argo`, 
+you go to `https://${CODESPACE_NAME}-8080.${GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN}/argo`
