-This script is used to set the version of the project.
-It only accepts release versions (not SNAPSHOT versions).
-To create a new stable release of RESTHeart, for example 8.2.0:
+This script sets the project version, commits the change, and optionally tags it.
 
-   $ ./setversion.sh 8.2.0
-   # This will automatically create a new release version and set the next version as a SNAPSHOT.
+Usage:
+   ./setversion.sh <version> [--dry-run]
+
+Options:
+   --dry-run  Preview the changes without actually making them.
+
+Examples:
+   To create a new release:
+       ./setversion.sh 8.1.4
+   To set a new SNAPSHOT version:
+       ./setversion.sh 8.1.5-SNAPSHOT
+   To preview the changes:
+       ./setversion.sh 8.1.4 --dry-run
+
+After running the script:
+   git push && git push --tags
