-# Agent Documentation
-
-This document describes how to create a new application chart for the homelab operator.
-
-## Chart Structure
-
-Each application has its own chart located in a directory under `charts/apps`. The chart should contain the following files:
-
-- `Chart.yaml`: The chart metadata.
-- `values.yaml`: The default values for the chart.
-- `templates/`: A directory containing the Kubernetes resource templates.
-
-## Custom Resources
-
-The homelab operator uses several custom resources to manage applications. These resources are defined in the `templates` directory of the chart.
-
-### `PostgresDatabase`
-
-If the application requires a PostgreSQL database, you can create a `PostgresDatabase` resource. The operator will automatically create a database and a secret containing the connection details. The secret will have the same name as the release with a `-pg-connection` postfix.
-
-Example:
-
-```yaml
-# templates/database.yaml
-apiVersion: homelab.mortenolsen.pro/v1
-kind: PostgresDatabase
-metadata:
-  name: "{{ .Release.Name }}"
-spec:
-  environment: "{{ .Values.globals.environment }}"
-```
-
-The secret has the following values:
-
-- `database`: name of the created database
-- `host`: the hostname of the postgres server
-- `port`: the port of the postgres server
-- `url`: combined url in the format `postgresql://{user}:{password}@{host}:{port}/{database}`
-
-### `OidcClient`
-
-If the application requires OIDC authentication, you can create an `OidcClient` resource. The operator will automatically create an OIDC client and a secret containing the client ID and secret. The secret will have the same name as the release with a `-client` postfix.
-
-You need to specify the redirect URIs for the OIDC client. The subdomain is taken from the `values.yaml` file.
-
-Example:
-
-```yaml
-# templates/client.yaml
-apiVersion: homelab.mortenolsen.pro/v1
-kind: OidcClient
-metadata:
-  name: "{{ .Release.Name }}"
-spec:
-  environment: "{{ .Values.globals.environment }}"
-  redirectUris:
-    - path: /user/oauth2/Authentik/callback
-      subdomain: "{{ .Values.subdomain }}"
-      matchingMode: strict
-```
-
-The secret has the following value:
-
-- `authorization`: Authorization endpoint
-- `clientId`
-- `clientSecret`
-- `configuration`: autodiscovery endpoint
-- `configurationIssuer`: issuer url
-- `endSession`: end session endpoint
-- `jwks`: jwks endpoint
-- `token`: token endpoint
-- `userinfo`: user info endpoint
-
-### `HttpService` and `ExternalHttpService`
-
-To expose the application, you can use either an `HttpService` or an `ExternalHttpService` resource.
-
-- `HttpService`: This will expose the application through the Istio gateway. This is for internal access only.
-- `ExternalHttpService`: This will expose the application through a CloudFlare tunnel. This is for external access.
-
-Both resources take a `subdomain` and a `destination` as parameters. The `destination` is the Kubernetes service to route traffic to.
-
-Example of `HttpService`:
-
-```yaml
-# templates/http-service.yaml
-apiVersion: homelab.mortenolsen.pro/v1
-kind: HttpService
-metadata:
-  name: "{{ .Release.Name }}"
-spec:
-  environment: "{{ .Values.globals.environment }}"
-  subdomain: "{{ .Values.subdomain }}"
-  destination:
-    host: "{{ .Release.Name }}.{{ .Release.Namespace }}.svc.cluster.local"
-    port:
-      number: 80
-```
-
-Example of `ExternalHttpService`:
-
-```yaml
-# templates/external-http-service.yaml
-apiVersion: homelab.mortenolsen.pro/v1
-kind: ExternalHttpService
-metadata:
-  name: "{{ .Release.Name }}"
-spec:
-  environment: "{{ .Values.globals.environment }}"
-  subdomain: "{{ .Values.subdomain }}"
-  destination:
-    host: "{{ .Release.Name }}.{{ .Release.Namespace }}.svc.cluster.local"
-    port:
-      number: 80
-```
-
-## `values.yaml`
-
-The `values.yaml` file should contain the following values:
-
-- `globals.environment`: The environment the application is running in (e.g., `prod`, `dev`).
-- `image.repository`: The Docker image repository.
-- `image.tag`: The Docker image tag.
-- `subdomain`: The subdomain for the application.
-
-Example:
-
-```yaml
-# values.yaml
-globals:
-  environment: prod
-image:
-  repository: docker.gitea.com/gitea
-  tag: latest
-subdomain: gitea
-```

+# ArgoCD Apps
+
+This Helm chart deploys an ArgoCD ApplicationSet and AppProject to manage homelab applications.
+
+## Description
+
+It sets up:
+-   **AppProject**: A project named `apps` (configurable) to group the applications.
+-   **ApplicationSet**: Automatically discovers and deploys Helm charts from `charts/apps/*` in the repository.
+
+## Prerequisites
+
+-   Kubernetes cluster
+-   ArgoCD installed in the `argocd` namespace
+
+## Deployment
+
+### Option 1: Helm Install
+
+Run the following command to install the chart directly:
+
+```bash
+helm upgrade --install argocd-apps ./charts/argocd-apps \
+  --namespace argocd
+```
+
+### Option 2: ArgoCD App of Apps
+
+You can also deploy this chart using ArgoCD itself by creating an Application that points to this chart.
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: Application
+metadata:
+  name: argocd-apps
+  namespace: argocd
+spec:
+  project: default
+  source:
+    repoURL: https://github.com/morten-olsen/homelab-apps
+    targetRevision: main
+    path: charts/argocd-apps
+  destination:
+    server: https://kubernetes.default.svc
+    namespace: argocd
+  syncPolicy:
+    automated:
+      prune: true
+      selfHeal: true
+```
+
+## Configuration
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `repoURL` | URL of the git repository | `https://github.com/morten-olsen/homelab-apps` |
+| `targetRevision` | Git revision to use | `main` |
+| `path` | Path to the apps directory | `charts/apps` |
+| `exclude` | Pattern to exclude directories | `*.disabled` |
+| `project` | ArgoCD project name | `apps` |
