 ### `version` and `appVersion` in Chart.yaml
 
-qwe asd zxc
+Plugin intentionally doesn't modify Chart.yaml during the release.
+It's recommended to use Git tags for maintaining release versions.
+
+The plugin leverages `--version` and `--app-version` when calling `helm package`
+to manage published chart versions and not rely on `Chart.yaml`.
+
+There's two usage scanarios for this plugin:
+
+1. The chart and the application are co-located in the same repository.
+
+    In this case, the `version` and `appVersion` are both changed during a release.
+    This is a default plugin's behaviour.
+
+1. The chart is maintained separately from the application.
+
+    In this case `appVersion` is modified outside of chart's release process
+    and must be updated manually in Chart.yaml. To prevent plugin from setting `--app-version` -
+    use `skipAppVersion` option.
