 In general you should try to stick with the configuration pre-defined by your project. But some plugins may be considered as personal flavor and are typically not predefined by the project config. Such plugins should be shipped with your link:settings.asciidoc[settings] as described above with `plugin_active=false` allowing you to easily install it manually. Surely, you can easily add plugins via the UI of VS code. However, be aware that some plugins may collect sensitive data or could introduce other vulnerabilities. So consider the governance of your project and talk to your technical lead before installing additional plugins that are not pre-defined in your link:settings.asciidoc[settings].
 
-As maintainer of the link:settings.asciidoc[settings] for your project you should avoid to ship too many plugins that may waste resources but are not used by every developer. By configuring additional plugins with `plugin_active=false` you can give your developers the freedom to install some additional plugins easily.
