+# App Template
+
+## Background
+
+Since Helm [library charts](https://helm.sh/docs/topics/library_charts/) cannot be
+installed directly I have created a companion chart for the [common library](../../common-library/introduction).
+
+## Usage
+
+In order to use this template chart, you would deploy it as you would any other Helm chart.
+By setting the desired values, the common library chart will render the desired resources.
+
+Be sure to check out the [common library docs](../../common-library/introduction)
+and its [`values.yaml`](https://github.com/bjw-s/helm-charts/tree/main/charts/library/common/values.yaml) for
+more information about the available configuration options.
+
+#### Example
+
+This is an example `values.yaml` file that would deploy the [echo-server](https://github.com/jmalloc/echo-server)
+application.
+
+```yaml
+image:
+  repository: docker.io/jmalloc/echo-server
+  tag: 0.3.3
+
+service:
+  main:
+    ports:
+      http:
+        port: 8080
+
+ingress:
+  main:
+    enabled: true
+    ingressClassName: "nginx"
+    hosts:
+      - host: &host "echo-server.${INGRESS_DOMAIN}"
+        paths:
+          - path: /
+    tls:
+      - hosts:
+          - *host
+
+resources:
+  requests:
+    cpu: 15m
+    memory: 64M
+  limits:
+    memory: 128M
+```
+
+## Source code

+The source code for the app template chart can be found

 !!! note
     The Common library chart is not meant to be installed directly, application
     charts use the Common library as a dependency.
+    See the [app template](../../app-template/introduction) for an example how to
