+# WGSL Analyzer
+
+To enable [WGSL](https://www.w3.org/TR/WGSL/) language support in your IDE, you can integrate the [wgsl-analyzer](https://github.com/wgsl-analyzer/wgsl-analyzer) by following these steps:
+
+![WGSL Analyzer demo](../images/user-defined-ls/wgsl-analyzer/demo_ls.gif)
+
+---
+
+## Step 1: Install the Language Server
+
+1. Open an `.wgsl` file in your project.
+2. Click on **Install WGSL Analyzer**:
+
+   ![Open file](../images/user-defined-ls/wgsl-analyzer/open_file.png)
+
+3. This will open the [New Language Server Dialog](../UserDefinedLanguageServer.md#new-language-server-dialog) with `Astro Language Server` pre-selected:
+
+   ![New Language Server Dialog](../images/user-defined-ls/wgsl-analyzer/new_language_server_dialog.png)
+
+4. Click **OK**. This will create the `WGSL Analyzer` definition and start the installation:
+
+   ![Installing Language Server](../images/user-defined-ls/wgsl-analyzer/language_server_installing.png)
+
+5. Once the installation completes, the server should start automatically and provide [WGSL](https://www.w3.org/TR/WGSL/) language support (autocomplete, diagnostics, etc.).
+
+### Troubleshooting Installation
+
+If the installation fails, you can customize the installation settings in the **Installer** tab,  
+then click on the **Run Installation** hyperlink to reinstall the server:
+
+![Installer tab](../images/user-defined-ls/wgsl-analyzer/installer_tab.png)
+
+See [Installer descriptor](../UserDefinedLanguageServerTemplate.md#installer-descriptor) for more information.
+
+---
+
+## Step 2: Install TextMate Bundle
+
+Since IntelliJ does not provide native WGSL TextMate support, and the language server does not handle syntax highlighting, you need to set up a TextMate bundle manually.
+
+* Clone the wgsl-analyzer repository:
+
+  ```bash
+  git clone https://github.com/wgsl-analyzer/wgsl-analyzer.git
+
+* Open TextMate Bundles settings
+
+![TextMate Bundles Settings](../images/user-defined-ls/textmate_bundles_settings.png)
+
+* Click the `+` button and select the folder [wgsl-analyzer/editors/code](https://github.com/wgsl-analyzer/wgsl-analyzer/tree/main/editors/code) folder.
+  This folder contains the package.json and the TextMate grammar.
+
+Once done, IntelliJ will apply syntax highlighting, bracket matching, and other basic editor features for .wgsl files.
