Looking good just a few suggestions!
| Developers have two options for using Ionic components: Standalone or Modules. This guide covers both options as well as the benefits and downsides of each approach. | ||
|
|
||
| While the Standalone approach is newer and makes use of more modern Angular APIs, the Modules approach will continue to be supported in Ionic. Most of the Angular examples on this documentation website use the Modules approach. | ||
| The Standalone approach makes use of modern Angular APIs and is the recommended way to use Ionic. The Modules approach and its `IonicModule` are **deprecated** as of Ionic 9 and will be removed in a future major version. Existing apps continue to work, but new apps should use the Standalone approach, and existing apps should plan to migrate. Refer to [Migrating from Modules to Standalone](#migrating-from-modules-to-standalone). |

I don't think we need to mention "as of Ionic 9" since the deprecation warning will only show up on v9.
| Developers can use Ionic components as standalone components to take advantage of treeshaking and newer Angular features. This option involves importing specific Ionic components in the Angular components you want to use them in. Developers can use Ionic standalone components even if their Angular application is NgModule-based. | ||

||
| See the [Standalone Migration Guide](#migrating-from-modules-to-standalone) for instructions on how to update your Ionic app to make use of Ionic standalone components. | ||

| 1. Ionic components need to be imported into every Angular component they are used in which can be time consuming to set up. | ||
|
|
||
| :::info Code splitting | ||
| Ionic ships standalone components from a single entry point (`@ionic/angular`). Bundlers such as Webpack and esbuild cannot split code from a single entry point across separate chunks, so the Ionic components you import are included in the main bundle rather than in the chunk for the route or component where they are used. Unused components are still tree-shaken out of the build. Refer to the [code splitting tracking issue](https://github.com/ionic-team/ionic-framework/issues/28574) for details. |

It seems weird to link to this issue - the issue is closed as not planned.
| ## Modules | ||
|
|
||
| :::warning Deprecation Notice | ||
| The Modules approach and its `IonicModule` are deprecated as of Ionic 9 and will be removed in a future major version. `IonicModule` remains fully functional in Ionic 9, so existing apps continue to work without changes. New apps should use the [Standalone](#standalone) approach, and existing apps should plan to migrate using the [migration guide](#migrating-from-modules-to-standalone). |

What is the current behavior?
The Angular documentation presents the Modules approach and
IonicModuleas a fully supported option with no indication that it is being phased out. The Build Options guide, the per config guides, and the Platform guide all showIonicModule.forRoot()examples, and the Ionic 9 upgrade guide does not mention the deprecation.What is the new behavior?
docs/angular/build-options.md: notes that the Modules approach andIonicModuleare deprecated as of Ionic 9, adds a Deprecation Notice admonition to the Modules section, and adds a code splitting note explaining the single entry point limitation of the standalone build.docs/updating/9-0.md: adds anIonicModuleDeprecation entry that points to the migration guide.docs/developing/config/*anddocs/angular/platform.md: add a deprecation comment above theIonicModuleexamples that points developers toprovideIonicAngular(). The Platform guide example is converted into Angular and Angular (Standalone) tabs so the standalone equivalent is shown alongside the Modules version.Does this introduce a breaking change?
