 The GitExtension enhances versioning by dynamically appending the Git hash before "snapshot" in the version string. For example, 0.0.0-SNAPSHOT becomes 0.0.0.0a2b3c4d-SNAPSHOT, ensuring each build reflects its commit origin, prevents overwriting existing versions. This feature aids developers during development by providing clear version identification.
 
+### Extension Info.
+
+The InfoExtension provides information for name and version, vendor name, and UTC timestamp.
