+description: Try Holos with this quick start guide.

+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+import Admonition from '@theme/Admonition';
+
+# Quickstart
+
+In this guide, you'll experience how Holos makes the process of operating a
+Platform safer, easier, and more consistent. We'll use Holos to manage a
+vendor-provided Helm chart as a Component. Next, we'll mix in our own custom
+resources to manage the Component with GitOps. Finally, you'll see how Holos
+makes it safer and easier to maintain software over time by surfacing the exact
+changes that will be applied when upgrading the vendor's chart to a new version,
+before they are actually made.
+
+The [Concepts](/docs/concepts) page defines capitalized terms such as Platform
+and Component.
+
+## What you'll need {#requirements}
+
+You'll need the following tools installed to complete this guide.
+
+1. [holos](/docs/install) - to build the Platform.
+2. [helm](https://helm.sh/docs/intro/install/) - to render Holos Components that
+wrap upstream Helm charts.
+
+Optionally, if you'd like to apply the rendered manifests to a real Cluster,
+first complete the [Local Cluster Guide](/docs/guides/local-cluster).
+
+## Install Holos
+
+Install Holos with the following command or other methods listed on the
+[Installation](/docs/install/) page.
+
+```bash
+go install github.com/holos-run/holos/cmd/holos@latest
+```
+
+## Create a Git Repository
+
+Start by initializing an empty Git repository. Holos operates on local files
+stored in a Git repository.
+
+<Tabs groupId="init">
+  <TabItem value="command" label="Command">
+    ```bash
+    mkdir holos-quickstart
+    cd holos-quickstart
+    git init
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    Initialized empty Git repository in /holos-quickstart/.git/
+    ```
+  </TabItem>
+</Tabs>
+
+This guide assumes you will run commands from the root directory of the Git
+repository unless stated otherwise.
+
+## Generate the Platform {#Generate-Platform}
+
+Generate the Platform code in the repository root. A Platform refers to the
+entire set of software holistically integrated to provide a software development
+platform for your organization. In this guide, the Platform will include a
+single Component to demonstrate how the concepts fit together.
+
+```bash
+holos generate platform quickstart
+```
+
+Commit the generated platform config to the repository.
+
+<Tabs groupId="commit-platform">
+  <TabItem value="command" label="Command">
+    ```bash
+    git add .
+    git commit -m "holos generate platform quickstart - $(holos --version)"
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    [main (root-commit) 0b17b7f] holos generate platform quickstart
+     213 files changed, 72349 insertions(+)
+     ...
+    ```
+  </TabItem>
+</Tabs>
+
+## Generate a Component {#generate-component}
+
+The platform you generated is currently empty. Run the following command to
+generate the CUE code that defines a Helm Component.
+
+<Tabs groupId="gen-podinfo">
+  <TabItem value="command" label="Command">
+    ```bash
+    holos generate component podinfo --component-version 6.6.1
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    generated component
+    ```
+  </TabItem>
+</Tabs>
+
+The --component-version 6.6.1 flag intentionally installs an older release.
+You'll see how Holos assists with software upgrades later in this guide.
+
+The generate component command creates two files: a leaf file,
+`components/podinfo/podinfo.gen.cue`, and a root file, `podinfo.gen.cue`. Holos
+leverages the fact that [order is
+irrelevant](https://cuelang.org/docs/tour/basics/order-irrelevance/) in CUE to
+register the component with the Platform by adding a file to the root of the Git
+repository. The second file defines the component in the leaf component
+directory.
+
+<Tabs groupId="podinfo-files">
+  <TabItem value="components/podinfo/podinfo.gen.cue" label="Leaf">
+    `components/podinfo/podinfo.gen.cue`
+    ```cue showLineNumbers
+    package holos
+
+    // Produce a helm chart build plan.
+    (#Helm & Chart).Output
+
+    let Chart = {
+      Name:      "podinfo"
+      Version:   "6.6.1"
+      Namespace: "default"
+
+      Repo: name: "podinfo"
+      Repo: url:  "https://stefanprodan.github.io/podinfo"
+
+      Values: {}
+    }
+    ```
+  </TabItem>
+  <TabItem value="podinfo.gen.cue" label="Root">
+    `podinfo.gen.cue`
+    ```cue showLineNumbers
+    package holos
+
+    // Manage podinfo on workload clusters only
+    for Cluster in #Fleets.workload.clusters {
+      #Platform: Components: "\(Cluster.name)/podinfo": {
+        path:    "components/podinfo"
+        cluster: Cluster.name
+      }
+    }
+    ```
+  </TabItem>
+</Tabs>
+
+In this example, we provide the minimal information needed to manage the Helm
+chart: the name, version, Kubernetes namespace for deployment, and the chart
+repository location.
+
+This chart deploys cleanly without any values provided, but we include an empty
+Values struct to show how Holos improves consistency and safety in Helm by
+leveraging the strong type-checking in CUE. You can safely pass shared values,
+such as the organization’s domain name, to all Components across all clusters in
+the Platform by defining them at the root of the configuration.
+
+Commit the generated component config to the repository.
+
+<Tabs groupId="commit-component">
+  <TabItem value="command" label="Command">
+    ```bash
+    git add .
+    git commit -m "holos generate component podinfo - $(holos --version)"

+     create mode 100644 podinfo.gen.cue
+    ```
+  </TabItem>
+</Tabs>
+
+## Render the Component
+
+You can render individual components without adding them to a Platform, which is
+helpful when developing a new component.
+
+<Tabs groupId="render-podinfo">
+  <TabItem value="command" label="Command">
+    ```bash
+    holos render component ./components/podinfo --cluster-name=default

+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    cached
+    rendered podinfo
+    ```
+  </TabItem>
+</Tabs>
+
+First, the command caches the Helm chart locally to speed up subsequent
+renderings. Then, the command runs Helm to produce the output and writes it into
+the deploy directory.
+
+<Tabs groupId="tree-podinfo">
+  <TabItem value="command" label="Command">
+    ```bash
+    tree deploy
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    deploy
+    └── clusters
+        └── default
+            └── components
+                └── podinfo
+                    └── podinfo.gen.yaml
+
+    5 directories, 1 file
+    ```
+  </TabItem>
+</Tabs>
+
+The component deploys to one cluster named `default`. In practice, the same
+component is often deployed to multiple clusters, such as `east` and `west` to
+provide redundancy and increase availability.
+
+:::tip
+This example is equivalent to running `helm template` on the chart and saving
+the output to a file. Holos simplifies this task, making it safer and more
+consistent when managing many charts.

+We've seen how Holos works with Helm, but we haven't yet explored how Holos
+makes it easier to consistently and safely manage all of the software in a
+Platform.
+
+Holos allows you to easily mix in resources that differentiate your Platform.
+We'll use this feature to mix in an ArgoCD [Application][application] to manage
+the podinfo Component with GitOps. We'll define this configuration in a way that
+can be automatically and consistently reused across all future Components added
+to the Platform.
+

+following contents:

+fact that [order is
+irrelevant](https://cuelang.org/docs/tour/basics/order-irrelevance/) in CUE.

+the ArgoCD configuration and render an Application manifest for GitOps
+management.

+
+In this section, we learned how Holos simplifies mixing resources into
+Components, like an ArgoCD Application. Holos ensures consistency by managing an
+Application resource for every Component added to the Platform through the
+configuration you define in `argocd.cue` at the root of the repository.
+
+## Define Workload Clusters {#workload-clusters}
+
+We've generated a Component to manage podinfo and integrated it with our
+Platform, but rendering the Platform doesn't render podinfo. Podinfo isn't
+rendered because we haven't assigned any Clusters to the workload Fleet.
+
+Define two new clusters, `east` and `west`, and assign them to the workload
+Fleet. Create a new file named `clusters.cue` in the root of your Git repository
+with the following contents:
+
+<Tabs groupId="clusters">
+  <TabItem value="clusters.cue" label="clusters.cue">
+    ```cue showLineNumbers
+    package holos
+
+    // Define two workload clusters for disaster recovery.
+    #Fleets: workload: clusters: {
+      // In CUE _ indicates values are defined elsewhere.
+      east: _
+      west: _
+    }
+    ```
+  </TabItem>
+</Tabs>
+
+This example shows how Holos simplifies configuring multiple clusters with
+similar configuration by grouping them into a Fleet.
+
+:::tip
+Fleets help segment a group of Clusters into one leader and multiple followers
+by designating one cluster as the primary. Holos makes it safer, easier, and
+more consistent to reconfigure which cluster is the primary. The primary can be
+set to automatically restore persistent data from backups, while non-primary
+clusters can be configured to automatically replicate from the primary.
+
+Automatic database backup, restore, and streaming replication is an advanced
+topic enabled by Cloud Native PG and CUE. Check back for a guide on this and
+other Day 2 operations topics.

+
+## Render the Platform {#render-platform}
+
+Render the Platform to render the podinfo Component for each of the workload
+clusters.

+## Upgrade a Helm Chart
+
+Holos is designed to ease the burden of Day 2 operations. With Holos, upgrading
+software, integrating new software, and making safe platform-wide configuration
+changes become easier.
+
+Let's upgrade the podinfo Component to see how this works in practice. First,
+update the Component version field to the latest upstream Helm chart version.
+
+<Tabs groupId="gen-podinfo">
+  <TabItem value="command" label="Command">
+    ```bash
+    holos generate component podinfo --component-version 6.6.2
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    generated component
+    ```
+  </TabItem>
+</Tabs>
+
+Remove the cached chart version.
+
+<Tabs groupId="gen-podinfo">
+  <TabItem value="command" label="Command">
+    ```bash
+    rm -rf components/podinfo/vendor
+    ```
+  </TabItem>
+</Tabs>
+
+Now re-render the Platform.
+
+<Tabs groupId="render-platform2">
+  <TabItem value="command" label="Command">
+    ```bash
+    holos render platform ./platform
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    rendered components/podinfo for cluster east in 327.10475ms
+    rendered components/podinfo for cluster west in 327.796541ms
+    ```
+  </TabItem>
+</Tabs>
+
+Notice we're still using the upstream chart without modifying it. The Holos
+component wraps around the chart to mix in additional resources and integrate
+the component with the broader Platform.
+
+## Visualize the Changes
+
+Holos makes it easier to see exactly what changes are made and which resources
+will be applied to the API server. By design, Holos operates on local files,
+leaving the task of applying them to ecosystem tools like `kubectl` and ArgoCD.
+This allows platform operators to inspect changes during code review, or before
+committing the change at all.
+
+For example, using `git diff`, we see that the only functional change when
+upgrading this Helm chart is the deployment of a new container image tag to each
+cluster.  Additionally, we can roll out this change gradually by applying it to
+the east cluster first, then to the west cluster, limiting the potential blast
+radius of a problematic change.

+
+## Recap {#recap}
+
+In this quickstart guide, we learned how Holos makes it easier, safer, and more
+consistent to manage a Platform composed of multiple Clusters and upstream Helm
+charts.
+
+We covered how to:
+
+1. Generate a Git repository for the Platform config.
+2. Wrap the unmodified upstream podinfo Helm chart into a Component.
+3. Render an individual Component.
+4. Mix-in your Platform's unique resources to all Components.  For example, ArgoCD Application resources.
+5. Define multiple similar, but not identical, workload clusters.
+6. Render the manifests for the entire Platform with the `holos render platform` command.
+7. Upgrade a Helm chart to the latest version as an important Day 2 task.
+8. Visualize and surface the details of planned changes Platform wide.
+
+## Dive Deeper
+
+If you'd like to dive deeper, check out the [Schema API][schema] and [Core
+API][core] reference docs. The main difference between the schema and core
+packages is that the schema is used by users to write refined CUE, while the
+core package is what the schema produces for `holos` to execute. Users rarely
+need to interact with the Core API when on the happy path, but can use the core
+package as an escape hatch when the happy path doesn't go where you want.

+# Manage a Project
+
+In this guide we'll explore how Holos easily, safely, and consistently manages
+platform resources for teams to develop the projects they're working on.
+
+Intended Audience: Platform Engineers and Software Engineers.
+
+Goal is to demonstrate how the platform team can consistently, easily, and
+safely provide platform resources to software engineers.
+
+Assumption is software engineers have a container they want to deploy onto the
+platform and make accessible.  We'll use httpbin as a stand-in for the dev
+team's container.
+
+Project is roughly equivalent to Dev Team for the purpose of this guide, but in
+practice multiple teams work on a given project over the lifetime of the
+project, so we structure the files into projects instead of teams.
+
+## What you'll need {#requirements}
+
+You'll need the following tools installed to complete this guide.
+
+1. [holos](/docs/install) - to build the Platform.
+2. [helm](https://helm.sh/docs/intro/install/) - to render Helm Components.
+3. [kubectl](https://kubernetes.io/docs/tasks/tools/) - to render Kustomize Components.
+
+If you'd like to apply the manifests we render in this guide complete the
+following optional, but recommended, steps.
+
+a. Complete the [Local Cluster] guide to set up a local cluster to work with.
+b. You'll need a GitHub account to fork the repository associated with this
+guide.
+
+## Fork the Guide Repository

+repository unless stated otherwise.
+
+[Quickstart]: /docs/quickstart
+[Local Cluster]: /docs/guides/local-cluster
+
+## Render the Platform
+
+So we can build the basic platform.  Don't dwell on the platform bits.
+
+## Apply the Manifests
+
+Deploy ArgoCD, but not any of the Application resources.
+
+## Browse to ArgoCD
+
+Note there is nothing here yet.
+
+## Switch to your Fork
+
+Note all of the Applications change consistently.
+
+## Apply the Applications
+
+Note how ArgoCD takes over management, no longer need to k apply.
+
+## Create a Project
+
+Project is a conceptual, not technical, thing in Holos.  Mainly about how components are laid out in the filesystem tree.
+
+We use a schematic built into holos as an example, the platform team could use the same or provide a similar template and instructions for development teams to self-serve.
+
+## Render the Platform
+
+Notice:
+
+1. Project is registered with the platform at the root.
+2. HTTPRoute and Namespace resources are added close to the root in `projects`
+3. Deployment and Service resources are added at the leaf in `projects/httpbin/backend`
+
+## Update the image tag
+
+Add a basic schematic to demonstrate this.  May need to add two new flags for image url and image tag to the generate subcommand, but should just be two new fields on the struct.
+
+## Dive Deeper
+
+Set the stage for constraints.  Ideas: Limit what resources can be added,
+namespaces can be operated in, enforce labels, etc...
+
+Simple, consistent, easy constraints.

 # Guides
 
+## Start with the [Quickstart] guide
+
+The guides are organized as a progression.  We'll use Holos to manage a
+fictional bank's platform, the Bank of Holos in each of the guides.  In doing so
+we'll take the time to explain the foundational concepts of Holos.
+
+1. [Quickstart] covers the foundational concepts of Holos.
+2. [Deploy a Service] explains how to deploy a containerized service using an
+existing Helm chart.  This guide then explains how to deploy a similar service
+safely and consistently with CUE instead of Helm.
+3. [Change a Service] covers the day two task of making configuration changes to
+deployed services safely and consistently.

+2. [helm](https://helm.sh/docs/intro/install/) - to render Holos Components that
+wrap Helm charts.
+3. [kubectl](https://kubernetes.io/docs/tasks/tools/) - to render Holos
+Components that render with Kustomize.
+
+If you plan to apply the changes we make, you may delete and re-create your
+local platform with the following commands.
+
+```bash
+./scripts/reset-cluster
+```
+
+Then apply the current manifests with:
+
+```bash
+./scripts/apply
+```
+
+## Fork the Git Repository

+Let's imagine the bank recently re-branded from The Bank of Holos to The
+Holistic Bank.  The software development team responsible for the front end
+website needs to update the branding accordingly.
+
+Let's explore how Holos catches errors early, before they land in production,
+then guides the team to the correct place to make a change.
+
+The bank front end web service is managed by the
+`projects/bank-of-holos/frontend/components/bank-frontend/` component which
+refers to the organization display name in `schema.gen.cue`.

+Line 78 of the bank-frontend cue file refers to `#Organization.DisplayName` to

+Let's change the name of the bank by defining a new name at the root of the

+Whoops, the development team defined a value that isn't allowed by the
+configuration.  Someone else in the organization placed a [constraint] on the
+configuration to ensure the display name contains only letters, numbers, and

+The new display name changed the frontend container, but it _also_ affected the
+app-projects component.  Submitting a pull request would trigger a code review
+from the platform engineering team who manages the app-projects component.
+Let's see how to narrow the change down to limit the scope to the bank's user
+facing services.  All of these serves are managed under
+`projects/bank-of-holos/` Move the `organization.cue` file we created into this
+folder to limit the scope of configuration to the the components contained within.
+
+```bash
+mv projects/organization.cue projects/bank-of-holos/
+```
+
+Render the platform and review what changed.

+
+## Apply the Change
+
+Once we've pushed the change, navigate to the [bank-frontend GitOps
+Application](https://argocd.holos.localhost/applications/argocd/bank-frontend?view=tree&resource=).
+We can see the Deployment needs to sync to the desired state we just pushed.
+
+![bank-frontend out of sync](./img/change-a-service-out-of-sync.png)
+
+Clicking on the frontend Deployment, we see the diff with the change we expect.
+
+![bank-frontend diff](./img/change-a-service-diff.png)
+
+Sync the change, ArgoCD applies the desired configuration state to the cluster
+and Kubernetes handles rolling out the updated Deployment resource.
+
+![bank-frontend progressing](./img/change-a-service-progressing.png)
+
+Soon, the deployment finishes and the component is in sync again.
+
+![bank-frontend in sync](./img/change-a-service-in-sync.png)
+
+Finally, let's see if the name actually changed on the website.  Navigate to
+https://bank.holos.localhost/.
+
+![bank-frontend login page](./img/change-a-service-login-page.png)
+
+Great!  We successfully made our change and successfully applied the changed
+configuration to the platform.
+
+- We saw how multiple teams are could be impacted by defining configuration at
+the `projects/` path.
+- We scoped our change to only affect components within the
+`projects/bank-of-holos/` path, limiting the impact on other teams.
+- We saw how CUE can be used to constrain values in Holos, increasing safety.
+- We saw how CUE surfaces the file and line number of _every_ place to look for
+where a value is defined, making it faster and easier to troubleshoot problems..
+
+Thanks for taking the time to work through this guide.

-# Expose a Service
-
-In this guide, you'll learn how to expose a service with Holos using the Gateway
-API.
-
-The [Concepts](/docs/concepts) page defines capitalized terms such as Platform
-and Component.
-
-## What you'll need {#requirements}
-
-You'll need the following tools installed to complete this guide.
-
-1. [holos](/docs/install) - to build the Platform.
-2. [helm](https://helm.sh/docs/intro/install/) - to render Helm Components.
-3. [kubectl](https://kubernetes.io/docs/tasks/tools/) - to render Kustomize Components.
-
-Optionally, if you'd like to apply the rendered manifests to a real Cluster,
-first complete the [localhost Guide](../local-cluster).
-
-## Create a Git Repository
-
-Start by initializing an empty Git repository. Holos operates on local files
-stored in a Git repository.
-
-<Tabs groupId="init">
-  <TabItem value="command" label="Command">
-```bash
-mkdir expose-a-service
-cd expose-a-service
-git init
-```
-  </TabItem>
-  <TabItem value="output" label="Output">
-```txt showLineNumbers
-Initialized empty Git repository in /expose-a-service/.git/
-```
-  </TabItem>
-</Tabs>
-
-This guide assumes you will run commands from the root directory of the Git
-repository unless stated otherwise.
-
-## Generate the Platform {#Generate-Platform}
-
-Start by generating a platform with one workload Cluster.  The `guide` Platform
-is intended as a starting point for all of our guides.
-
-<Tabs groupId="generate-platform">
-  <TabItem value="command" label="Command">

-
-## Gateway API
-
-The Gateway API is an official Kubernetes project focused on L4 and L7 routing .
-You'll use the custom resources defined by the Gateway API to expose the httpbin
-service outside of the cluster.  The Kubernetes Gateway API does not come
-installed by default on most Kubernetes clusters, so we need to manage the
-custom resource definitions (CRDs).
-
-Run the following command to generate a Component to manage the Gateway API.
-
-<Tabs groupId="gen-gateway-api">
-  <TabItem value="command" label="Command">
-```bash
-holos generate component gateway-api
-```
-  </TabItem>
-  <TabItem value="output" label="Output">
-```txt showLineNumbers
-generated component
-```
-  </TabItem>
-</Tabs>
-
-The command generates two main configuration files, one at the leaf, and another
-at the root of the tree.  At the leaf, the config produces a Kustomize build
-plan for Holos to render.  At the root, the config adds the Component to all
-Clusters in the Platform.
-
-Notice the `kustomization.yaml` file at the leaf.  This is an unmodified
-upstream copy of the standard way to install the Gateway API.

-## Namespaces
-
-We often need to manage namespaces prior to workloads being deployed.  This is
-necessary because a namespace is a security boundary.  Holos makes it easier,
-safer, and more consistent to manage service accounts, role bindings, and
-secrets prior to deploying workloads into a namespace.
-
-We'll see how this works with the namespaces component, which offers a mechanism
-for other components to register their namespaces.  The namespaces component
-initializes each registered namespace, optionally mixing in resources
-consistently.
-
-Run the following command to generate the namespaces component.
-
-<Tabs groupId="gen-namespaces">
-  <TabItem value="command" label="Command">
-```bash
-holos generate component namespaces
-```
-  </TabItem>
-  <TabItem value="output" label="Output">
-```txt showLineNumbers
-generated component
-```
-  </TabItem>
-</Tabs>
-
-The command generates two main configuration files like we've seen with other
-components.  One file at the leaf, and another at the root.  The leaf uses a
-Kubernetes build plan to produce resources directly from CUE.
-
-<Tabs groupId="namespaces-files">
-  <TabItem value="components/namespaces/namespaces.cue" label="Leaf">

-	// highlight-next-line

-```
-  </TabItem>
-  <TabItem value="namespaces.gen.cue" label="Root">

-```cue showLineNumbers
-package holos
-
-import corev1 "k8s.io/api/core/v1"
-
-// #Namespaces defines all managed namespaces in the Platform.
-// Holos adopts the sig-multicluster position of namespace sameness.

-			cluster: Cluster.name
-		}
-	}
-}
-```
-  </TabItem>
-</Tabs>
-
-Notice the highlighted line in the leaf file.  Resources are managed directly in
-CUE at the leaf using the Kubernetes component.  This is the same mechanism used
-to mix-in resources to Helm and Kustomize components.  The leaf refers to
-`#Namespaces` defined at the root.  At the root `#Namespaces` enforces a
-constraint: each Namespace must conform to the `k8s.io/api/core/v1`
-specification.
-
-:::important
-We've covered three kinds of components so far.  The [Quickstart] guide
-introduced Helm.  We've used Kustomize and Kubernetes in this guide.
-
-Holos offers a consistent way to manage these different kinds of packaging
-safely and easily.
-:::
-
-- At the **leaf** Holos tailors the component to your platform, mixing
-in resources and customizing the rendered output.
-- At the **root** Holos integrates a component with the rest of your platform.
-
-You'll see this pattern again and again as you build your platform.
-
-Render the platform to render the component for the workload clusters.

-These components share the configuration defined at the root in `istio.gen.cue`.
-
-Let's review how Holos makes it safer and easier to share Helm values defined at
-the root with the istiod and cni components defined at the leaf.
-
-1. istiod and cni use version `"1.23.1"` and namespace `"istio-system"` defined at
-the root.
-2. The Helm value to configure ambient (sidecar-less) mode is defined once at
-the root.
-3. The root adds a constraint to fail validation if the istio system namespace
-is not `"istio-system"`.  Future upgrades are safer with this constraint, if the
-upstream vendor changes the default in the future the component will fail
-validation.
-4. The root registers two Namespaces, `"istio-system"` and `"istio-ingress"`.
-5. The root manages the components on all workload clusters in the platform.

 # Introduction

+Welcome to Holos.  Holos is an open source tool to manage software development
+platforms safely, easily, and consistently.  We built Holos to help engineering
+teams work more efficiently together by empowering them to build golden paths
+and paved roads for other teams to leverage for quicker delivery.
+
+## Documentation
+
+- [Guides] are organized into example use-cases of how Holos helps engineering
+teams at the fictional Bank of Holos deliver business value on the bank's
+platform.
+- The [API Reference] is a technical reference for when you're writing CUE code to define your platform.
+
+## Backstory
+
+At [Open Infrastructure Services], each of us has helped dozens of companies
+build and operate their software development platform over the course of our
+career.  During the U.S. presidential election just before the pandemic our
+second largest client, Twitter, had a global outage lasting the better part of a
+day.  At the time, we were helping the core infrastructure team by managing
+their production configuration management system so the team could focus on
+delivering key objectives for the business.  In this position, we had a front
+row seat into what happened that day.
+
+One of Twitter's employees, a close friend of ours and engineer on the team,
+landed a trivial one line change to the firewall configuration.  Less than 30
+minutes later literally everything was down.  The one line change, which passed
+code review and seemed harmless, resulted in the host firewall reverting to the
+default state on hundreds of thousands of servers.  All connections to all
+servers globally were blocked and dropped.  Except SSH, thankfully.  At least
+one Presidential candidate complained loudly.
+
+This incident led us to deeply consider a few key problems about Twitter's
+software development platform, problems which made their way all the way up to
+the board of directors to solve.
+
+1. **Lack of Visibility** - There was no way to see clearly the impact a simple one-line
+change could have on the platform.  This lack of visibility made it difficult
+for engineers to reason about changes they were writing and reviewing.
+2. **Large Blast Radius** - All changes, no matter how small or large, affected the
+entire global fleet within 30 minutes.  Twitter needed a way to cap the
+potential blast radius to prevent global outages.
+3. **Incomplete Tooling** - Twitter had the correct processes in place, but
+their tooling didn't support their process.  The one line change was tested and
+peer reviewed prior to landing, but the tooling didn't surface the information
+they needed when they needed it.
+
+Over the next few years we built features for Twitter's configuration management
+system that solved each of these problems.  At the same time, I started
+exploring my curiosity of what these solutions would look like in the context of
+Kubernetes and cloud native software instead of a traditional configuration
+management context.
+
+As Google Cloud partners, we had the opportunity to work with Google's largest
+customers and learn how they built their software development platforms on
+Kubernetes.  Over the course of the pandemic, we built a software development
+platform made largely in the same way, taking off the shelf CNCF projects like
+ArgoCD, the Kubernetes Prometheus Stack, Istio, Cert Manager, External Secrets
+Operator, etc... and integrating them into a holistic software development
+platform.  We started with the packaging recommended by the upstream project.
+Helm was and still is the most common distribution method, but many projects
+also provided plain yaml, kustomize bases, or sometimes even jsonnet in the case
+of the prometheus community.  We then wrote scripts to mix-in the resources we
+needed to integrate each piece of software with the platform as a whole. For
+example, we often passed Helm's output to Kustomize to add common labels or fix
+bugs in the upstream chart, like missing namespace fields.  We wrote umbrella
+charts to mix in Ingress, HTTPRoute, and ExternalSecret resources to the vendor
+provided chart.
+
+We viewed these scripts as necessary glue to assemble and fasten the components
+together into a platform, but we were never fully satisfied with them.  Umbrella
+charts became difficult to maintain once there were multiple environments,
+regions, and cloud providers in the platform.  Nested for loops in yaml
+templates created significant friction and were a challenge to troubleshoot
+because they obfuscated what was happening. The scripts, too, made it difficult
+to see what was happening, when, and fix issues in them that affected all
+components in the platform.
+
+Despite the makeshift scripts and umbrella charts, the overall approach had a
+significant advantage. The scripts always produced fully rendered manifests
+stored in plain text files.  We committed these files to version control and
+used ArgoCD to apply them. The ability to make a one-line change, render the
+whole platform, then see clearly what changed platform-wide resulted in less
+time spent troubleshooting and fewer errors making their way to production.
+
+For awhile, we lived with the scripts and charts.  I couldn't stop thinking
+about the [Why are we templating
+YAML?](https://hn.algolia.com/?dateRange=all&page=0&prefix=false&query=https%3A%2F%2Fleebriggs.co.uk%2Fblog%2F2019%2F02%2F07%2Fwhy-are-we-templating-yaml&sort=byDate&type=story)
+post on Hacker News though.  I was curious what it would look like to replace
+our scripts and umbrella charts with something that helped address the 3 main
+problems Twitter experienced.
+
+After doing quite a bit of digging and talking with folks, I found
+[CUE](https://cuelang.org).  I took our scripts and charts and re-wrote the same
+functionality we needed from the glue-layer in Go and CUE. The result is a new
+tool, `holos`, built to complement Helm, Kustomize, and JSonnet, but not replace
+them.  Holos leverages CUE to make it easier and safer for teams to define
+golden paths and paved roads without having to write bespoke, makeshift scripts
+or template text.
+
+Thanks for reading this far, give Holos a try locally with out [Quickstart]
+guide.

-1. Also built on CUE.
-2. Intended to create an Application abstraction.
-3. Holos prioritizes composition over abstraction.
-4. An abstraction of an Application acts as a filter that removes all but the lowest common denominator functionality.  The Holos Authors have found this filtering effect to create excessive friction for software developers.
-5. Holos focuses instead on composition to empower developers and platform engineers to leverage the unique features and functionality of their software and platform.
