+### `common.serviceAccount`
+
+The `common.serviceAccount` template accepts a list of three values:
+
+- `$top`, the top context
+- `$serviceAccount`, a dictionary of values used in the service account template
+- [optional] the template name of the overrides
+
+It creates a basic `ServiceAccount` resource with the following defaults:
+
+- The name is set with `common.serviceAccountName`
+- Lays out the annotations using `$serviceAccount.annotations`
+
+An example values file that can be used to configure the `ServiceAccount` resource is:
+
+```yaml
+serviceAccount:
+  create: true
+  annotations: {}
+  name:
+```
+
+Example use:
+
+```yaml
+{{- include "common.serviceAccount" (list . .Values.serviceAccount) -}}
+
+## The following is the same as above:
+# {{- include "common.serviceAccount" (list . .Values.serviceAccount "mychart.serviceAccount") -}}
+# {{- define "mychart.serviceAccount" -}}
+# {{- end -}}
