+## Note on Global Property declaration
+
+There are _two ways_ to provide selective generation properties or "global properties". First, these can be passed as Java System Properties. Second, these can be passed via the global property tooling option (`--global-property` in CLI and `globalProperty` in Maven and Gradle configurations). This differentiation is new in version 5.0 with the removal of the `-D` CLI option and the renaming of `systemProperties`. If you're upgrading to OpenAPI Generator 5.0+
+
+While the examples seen in [Customization](./customization.md) use the Java System Property syntax, keep in mind that the following are equivalent:
+
+```sh
+java -Dmodels {jar} generate {opts}
+```
+
+and
+
+```sh
+java {jar} generate {opts} --global-property=models
+```
+
+Why the two differing ways to provide the same properties? We previously accepted a `-D` tooling option which resembled Java System Property declaration. In older versions of OpenAPI Generator, the option modified the SystemProperties collection directly and was truly a "system property". This option changed during the 4.x release in an effort to make OpenAPI Generator thread-safe and isolate its configuration via thread locals. We no longer mutate System Properties. In the 4.x release and earlier, specifying the tooling `-D` option with system properties intended for other tools like swagger-parser rather than passing them as true Java System Properties would lead to unexpected behavior for the user; if our tool set the system property _after_ invoking certain code, it would seem to the user like Java System Properties weren't working!
