+### Maintenance schedule
+Starting from `v4.0.0`, the project maintenance will become much more regular.
+A new release will be published on a monthly basis to keep the package
+dependencies, package configurations and APIs / syntax up to date.
+
+Maintenance work will begin on 1st of each month, and expect the new version to
+be released within the first week of the month. New features from different
+tools integrated in this boilerplate might not always be implemented at once,
+especially on experimental features. If you want any particular feature to be
+implemented, please [file an issue], or consider make a [new pull request].
