-### Getting the version
+### Versions
 
 You can check the version of _Black_ you have installed using the `--version` flag.
 
 ```console
 $ black --version
-black, version 21.5b0
+black, version 21.9b0
 ```
 
+An option to require a specific version to be running is also provided.
+
+```console
+$ black --required-version 21.9b0 -c "format = 'this'"
+format = "this"
+$ black --required-version 31.5b2 -c "still = 'beta?!'"
+Oh no! 💥 💔 💥 The required version does not match the running version!
+```
+
+This is useful for example when running _Black_ in multiple environments that haven't
+necessarily installed the correct version. This option can be set in a configuration
+file for consistent results across environments.
+
 ## Configuration via a file
 
 _Black_ is able to read project-specific default values for its command line options
