core: define generic command core type for all kinds of tasks

Previously the Command core type was only useful for Validators and was
a bit hacky in that Holos appends the directory to the end of the
argument vector.

This patch changes the Command type to represent a generic command for
use as a Generator, Transformer, or Validator.  The type is extended to
support the semantics of reading output from a file, directory, or
standard output pipe.

Go templates are used to fill in Holos managed data values, for example
the temporary directory associated with the pipeline task.  The TaskData
structu represents these values passed into the template engine.

-Building and maintaining a software development platform is a complex and time
-consuming endeavour.  Organizations often dedicate a team of 3-4 who need 6-12
-months to build the platform.
+[Holos] is a configuration management tool for Kubernetes implementing the
+[rendered manifests pattern]. It handles configurations ranging from single
+resources to multi-cluster platforms across regions.
 
-Holos is a tool and a reference platform to reduce the complexity and speed up
-the process of building a modern, cloud native software development platform.
+Key components:
+- Platform schemas defining component integration
+- Building blocks unifying Helm, Kustomize and Kubernetes configs with CUE
+- BuildPlan pipeline for generating, transforming and validating manifests
 
-- **Accelerate new projects** - Reduce time to market and operational complexity by starting your new project on top of the Holos reference platform.
-- **Modernize existing projects** - Incrementally incorporate your existing platform services into Holos for simpler integration.
-- **Unified configuration model** - Increase safety and reduce the risk of config changes with CUE.
-- **First class Helm and Kustomize support** - Leverage and reuse your existing investment in existing configuration tools such as Helm and Kustomize.
-- **Modern Authentication and Authorization** - Holos seamlessly integrates platform identity and access management with zero-trust beyond corp style authorization policy.

-## Docs and Support
+## Setup
 
-The documentation for developing and using Holos is available at: https://holos.run
+```shell
+brew install holos-run/tap/holos
+```
 
-For discussion and support, [open a discussion](https://github.com/orgs/holos-run/discussions/new/choose).
+Refer to [setup] for other installation methods and dependencies.
+
+## Example
+
+See our [tutorial] for a complete hello world example.
+
+```cue showLineNumbers
+package holos
+
+holos: Component.BuildPlan
+
+Component: #Helm & {
+	Name: "podinfo"
+	Chart: {
+		version: "6.6.2"
+		repository: {
+			name: "podinfo"
+			url:  "https://stefanprodan.github.io/podinfo"
+		}
+	}
+	Values: ui: {
+		message: string | *"Hello World" @tag(message, type=string)
+	}
+}
+```
+
+## Organizational Role
+
+Platform engineers use Holos to generate Kubernetes manifests, both locally and
+in CI pipelines. The manifests are committed to version control and deployed via
+GitOps tools like ArgoCD or Flux.
+
+Holos integrates seamlessly with existing Helm charts, Kustomize bases, and
+other version-controlled configurations.
+
+## Advantages of Holos
+
+### Safe
+
+Holos leverages [CUE] for strong typing and validation of configuration data,
+ensuring consistent output from Helm and other tools.
+
+### Consistent
+
+A unified pipeline processes all configurations - whether from CUE, Helm, or
+Kustomize - through the same well-defined stages.
+
+### Flexible
+
+Composable building blocks for generation, transformation, validation and
+integration let teams assemble workflows that match their needs.
+
+The core is intentionally unopinionated about platform configuration patterns.
+Common needs like environments and clusters are provided as customizable
+[topics] recipes rather than enforced structures.
+
+## Getting Help
+
+Get support through our [Discord] channel or [GitHub discussions]. Configuration
+challenges arise at all experience levels - we welcome your questions and are
+here to help.

+// # Core API
+//
+// Package v1alpha4 contains the core API contract between the holos cli and CUE
+// configuration code.  Platform designers, operators, and software developers
+// use this API to write configuration in CUE which holos loads.  The Core API
+// is declarative.  Each resource represents a desired state necessary for holos
+// to fully render Kubernetes manifests into plain files.
+//
+// The following resources provide important context for the Core API.  The
+// [Author API] is intended for component authors as a convenient adapter for
+// the Core API resources Holos expects.
+//
+//  1. [Technical Overview]
+//  2. [Quickstart]
+//  3. [Author API]
+//
+// # Platform
+//
+// [Platform] defines the complete configuration of a platform.  A platform
+// represents a [Component] collection.
+//
+// Inspect a Platform resource holos would process by executing:
+//
+//	cue export --out yaml ./platform
+//
+// # Component
+//
+// A [Component] is the combination of CUE code along one path relative to the
+// platform root directory plus data injected from the [PlatformSpec] via CUE tags.
+// The platform configuration root is the directory containing cue.mod.
+//
+// A [Component] always produces exactly one [BuildPlan].
+//
+// # BuildPlan
+//
+// A [BuildPlan] contains an [Artifact] collection.  A BuildPlan often produces
+// two artifacts, one containing the fully rendered Kubernetes API resources,
+// the other containing an additional resource to manage the former with GitOps.
+// For example, a BuildPlan for a podinfo component produces a manifest
+// containing a Deployment and a Service, along with a second manifest
+// containing an ArgoCD Application.
+//
+// Inspect a BuildPlan resource holos render component would process by executing:
+//
+//	cue export --out yaml ./projects/platform/components/namespaces
+//
+// # Artifact
+//
+// An [Artifact] is one fully rendered manifest file produced from the final
+// [Transformer] in a sequence of transformers.  An Artifact may also be
+// produced directly from a [Generator], but this use case is uncommon.
+//
+// # Transformer
+//
+// A [Transformer] takes multiple inputs from prior [Generator] or [Transformer]
+// outputs, then transforms the data into one output.  [Kustomize] is the most
+// commonly used transformer, though a simple [Join] is also supported.
+//
+//  1. [Kustomize] - Patch and transform the output from prior generators or
+//     transformers.  See [Introduction to Kustomize].
+//  2. [Join] - Concatenate multiple prior outputs into one output.
+//
+// # Generators
+//
+// A [Generator] generates Kubernetes resources.  [Helm] and [Resources] are the
+// most commonly used, often paired together to mix-in resources to an
+// unmodified Helm chart.  A simple [File] generator is also available for use
+// with the [Kustomize] transformer.
+//
+//  1. [Resources] - Generates resources from CUE code.
+//  2. [Helm] - Generates rendered yaml from a [Chart].
+//  3. [File] - Generates data by reading a file from the component directory.

+# Guides
+
+## Technical Overview
+
+Please see the [Technical Overview] to learn about Holos.  If you're ready to
+drive in and try Holos, please work through the following guides.
+
+## Bank of Holos
+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.

+
+# Change a Service
+
+In this guide, we'll explore how Holos supports the frontend development team at [Bank of Holos] in reconfiguring an already deployed service. Along the way, we'll demonstrate how simple configuration changes are made safer with type checking, and how rendering the complete platform provides clear visibility into those changes.
+
+This guide builds on the concepts covered in the [Quickstart] and [Deploy a Service] guides.
+
+## What you'll need {#requirements}
+
+Like our other guides, this guide is intended to be useful without needing to
+run each command.  If you'd like to apply the manifests to a real Cluster,
+complete the [Local Cluster Guide](/docs/guides/local-cluster) before this
+guide.
+
+You'll need the following tools installed to run the commands in this guide.
+
+1. [holos](/docs/install) - to build the Platform.
+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.
+
+## Fork the Git Repository
+
+If you haven't already done so, [fork the Bank of
+Holos](https://github.com/holos-run/bank-of-holos/fork) then clone the
+repository to your local machine.
+
+<Tabs groupId="git-clone">

+
+Run the rest of the commands in this guide from the root of the repository.
+
+If you plan to apply the changes we make, you can delete and re-create your
+local platform synced to the start of this guide.
+
+```bash
+./scripts/reset-cluster
+./scripts/apply
+```
+
+## Rename the Bank
+
+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 best 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 7 of the `schema.cue` file defines the _default_ value for

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

+The new display name changed the frontend container, but it _also_ affected the
+app-projects component owned by the platform team.
+:::
+
+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 services are managed under `projects/bank-of-holos/` Move the
+`organization.cue` file into this folder to limit the scope of configuration to
+the the components contained within.

+
+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)
+
+:::tip Success
+We successfully made our change and successfully applied the changed
+configuration to the platform.
+:::
+
+Thanks for taking the time to work through this guide which covered:
+
+- How multiple teams could be impacted by defining configuration at the
+`projects/` path.
+- How to scope our change to only affect components within the
+`projects/bank-of-holos/` path, eliminating the impact on other teams.
+- How CUE can [constrain] values in Holos, increasing safety.
+- How to handle a [default value] in CUE.
+- 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.

+description: Try Holos with this quick start guide.
+slug: /archive/2024-09-15-quickstart
+sidebar_position: 100
+---
+
+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)"
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">

+     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.
+:::
+
+## Mix in an ArgoCD Application
+
+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.
+
+Create a new file named `argocd.cue` in the root of your Git repository with the
+following contents:
+
+<Tabs groupId="argocd-config">
+  <TabItem value="command" label="argocd.cue">
+    ```cue showLineNumbers
+    package holos
+
+    #ArgoConfig: {
+      Enabled: true
+      RepoURL: "https://github.com/holos-run/holos-quickstart-guide"
+    }
+    ```
+  </TabItem>
+</Tabs>
+
+:::tip
+If you plan to apply the rendered output to a real cluster, change the
+`example.com` RepoURL to the URL of the Git repository you created in this
+guide. You don't need to change the example if you're just exploring Holos by
+inspecting the rendered output without applying it to a live cluster.
+:::
+
+With this file in place, render the component again.
+
+<Tabs groupId="render-podinfo-argocd">
+  <TabItem value="command" label="Command">
+    ```bash
+    holos render component ./components/podinfo --cluster-name=default
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    wrote deploy file
+    rendered gitops/podinfo
+    rendered podinfo
+    ```
+  </TabItem>
+</Tabs>
+
+Holos uses the locally cached chart to improve performance and reliability. It
+then renders the Helm template output along with an ArgoCD Application resource
+for GitOps.
+
+:::tip
+By defining the ArgoCD configuration at the root, we again take advantage of the
+fact that [order is
+irrelevant](https://cuelang.org/docs/tour/basics/order-irrelevance/) in CUE.
+:::
+
+Defining the configuration at the root ensures all future leaf Components take
+the ArgoCD configuration and render an Application manifest for GitOps
+management.

+  </TabItem>
+</Tabs>
+

+Holos generates a similar Application resource for every additional Component

+
+Finally, add and commit the results to your Platform's Git repository.

+
+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.

+## 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.
+

+
+## 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.
