+### Dependencies management
+
+This Template project depends on Gradle plugins and external libraries – and during the development, you will add more of them.
+
+Keeping the project in good shape and having all the dependencies up-to-date requires time and effort, but it is possible to automate that process using [dependabot][gh:dependabot].
+
+Dependabot is a bot provided by GitHub for checking the build configuration files and reviewing any outdated or insecure dependencies of yours – in case if any update is available, it creates a new pull request providing [the proper change][gh:dependabot-pr].
+
+> **Note:** Dependabot doesn't yet support checking of the Gradle Wrapper. Check the [Gradle Releases][gradle-releases] page and update it with:
+> ```bash
+> ./gradlew wrapper --gradle-version 6.8 --distribution-type=all
+> ```

 ### Changelog maintenance
 
 When releasing an update, it is important to let your users know what the new version offers. The best way to do this is to provide release notes.
