 # Angular Language Service
 
-![demo](https://github.com/angular/vscode-ng-language-service/raw/main/demo.gif)
-
-## Features
-
-This extension provides a rich editing experience for Angular templates, both inline
-and external templates including:
-
-* Completions lists
-* AOT Diagnostic messages
-* Quick info
-* Go to definition
-
-## Download
-
-Download the extension from [Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=Angular.ng-template).
-
-## Configuring compiler options for the Angular Language Service
-
-The Angular Language Service uses the same set of options that are used to compile the application.
-To get the most complete information in the editor, set the `strictTemplates` option in `tsconfig.json`,
-as shown in the following example:
-
-```
-"angularCompilerOptions": {
-  "strictTemplates": true
-}
-```
-
-For more information, see the [Angular compiler options](https://angular.io/guide/angular-compiler-options) guide.
-
-## Versioning
-
-The language service extension relies on the `@angular/language-service` and `typescript` packages
-for its backend. `@angular/language-service` is always bundled with the extension, and is always
-the latest version at the time of the release.
-`typescript` is loaded, in order of priority, from:
-
-1. The path specified by `typescript.tsdk` in project or global settings.
-2. _(Recommended)_ The version of `typescript` bundled with the Angular Language Service extension.
-3. The version of `typescript` present in the current workspace's node_modules.
-
-We suggest **not** specifying `typescript.tsdk` in your VSCode settings
-per method (1) above. If the `typescript` package is loaded by
-methods (1) or (3), there is a potential for a mismatch between
-the API expected by `@angular/language-service` and the API provided by `typescript`. This could
-lead to a failure of the language service extension.
-
-For more information, please see [#594](https://github.com/angular/vscode-ng-language-service/issues/594).
-
-## Installing a particular release build
-
-Download the `.vsix` file for the release that you want to install from the [releases](https://github.com/angular/vscode-ng-language-service/releases) tab.
-
-*Do not open the .vsix file directly*. Instead, in Visual Studio code, go to the extensions tab. Click on the "..." menu in the upper right corner of the extensions tab, select "Install from vsix..." and then select the .vsix file for the release you just downloaded.
-
-The extension can also be installed with the following command:
-
-```
-code --install-extension /path/to/ngls.vsix
-```
