+### Building
+
+The `openapi-generator-cli` can be built using the following command. This will generate the `openapi-generator-cli.jar` in the `modules/openapi-generator-cli/target` directory without running the tests and generating the Javadocs.
+
+```shell
+./mvnw clean install -DskipTests -Dmaven.javadoc.skip=true
+```
+
+Or on Windows:
+
+```shell
+mvnw.cmd clean install -DskipTests -Dmaven.javadoc.skip=true
+```
+
+The binary can run via `java -jar`. For example:
+
+```shell
+java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar help
+```
