+### Updating dependencies
+
+It's a good practice to periodically check for possible dependency upgrades. Ideally, we should do it before every release.
+
+```sh
+mvn versions:display-property-updates
+```
+
+If appropriate, update dependency version with this command:
+
+```sh
+mvn versions:update-properties
+```
+
+Commit all version upgrades in a single commit, unless there's a good reason not to.
