 ### Disabling cache
 
-Cache is enabled by default, but can be disabled by setting the `no-cache` property to `true`:
+Disable cache using the [docker-options] plugin:
 
 ```shell
-dokku builder-nixpacks:set node-js-app no-cache true
-```
-
-The default value may be set by passing an empty value for the option:
-
-```shell
-dokku builder-nixpacks:set node-js-app no-cache
-```
-
-The `no-cache` property can also be set globally. The global default is `false`, and the global value is used when no app-specific value is set.
-
-```shell
-dokku builder-nixpacks:set --global no-cache true
-```
-
-The default value may be set by passing an empty value for the option.
-
-```shell
-dokku builder-nixpacks:set --global no-cache
+dokku docker-options:add node-js-app build "--no-cache"
 ```
