 > Without setting any optional parameter, the `copy()` method will produce an exact copy of the original version.
 
 ## Invalid version handling
 When the version or constraint parsing fails due to an invalid format, the library throws a specific `SemverException`.
+> **Note**:
 > The `Version::parseOrNull()` and `Constraint::parseOrNull()` methods can be used for exception-less conversions as they return `null` when the parsing fails.
