+### `common.fullname`
+
+The `common.fullname` template generates a name suitable for the `name:` field in Kubernetes metadata. It is used like this:
+
+```yaml
+name: {{ include "common.fullname" . }}
+```
+
+This prints the value of `{{ .Release.Name }}-{{ .Chart.Name }}` by default, but can be overridden with `.Values. fullnameOverride`:
+
+```yaml
+fullnameOverride: some-name
+```
+
+Example output:
+
+```yaml
+---
+# with the values above
+name: some-name
+
+---
+# the default, for release "release-name" and chart "mychart"
+name: release-name-mychart
+```
+
+Output of this function is truncated at 63 characters, which is the maximum length of name.

 ### `common.labels`
 
 `common.selectorLabels` prints the standard set of labels.
