-At its core a preset is a generator, which we can create inside of a plugin.
+At its core, a preset is a special [generator](/plugin-features/use-code-generators) that is shipped as part of an Nx Plugin package.
 
-All first-party Nx presets are built into nx itself, but you can [create your own plugin](/plugins/intro/getting-started) and create a generator with the magic name: `preset`. Once you've [published your plugin](/plugins/tutorials/publish-plugin) on npm, you can now run. the create-nx-workspace command with the preset option set to the name of your published package.

They include a [preset generator](https://github.com/qwikifiers/qwik-nx/tree/main/packages/qwik-nx/src/generators/preset) that you can use to create a new Nx workspace with Qwik support.
 
 ```shell
 npx create-nx-workspace --preset=qwik-nx
 ```
 
-This command will create a new Qwik preset based on the [published npm package: `qwik-nx`](https://www.npmjs.com/package/qwik-nx). If we check this package's source code, we can see that it has a [generator named `preset`](https://github.com/qwikifiers/qwik-nx/tree/main/packages/qwik-nx/src/generators/preset).
+## Create a new Nx plugin
 
 If you **don't** have an existing plugin you can create one by running
 
 ```shell
-  npx create-nx-plugin my-org --pluginName my-plugin
+npx create-nx-plugin my-org --pluginName my-plugin
 ```
 
+## Creating a "Preset" generator

 To create our preset inside of our plugin we can run
 
 ```shell
-  nx generate @nx/plugin:generator --name=preset --project=happynrwl
+nx generate @nx/plugin:generator --name=preset --project=happynrwl
 ```
