-# Installation des Intellij Language Clients
-
-Um den Language Client für Intellij installieren zu können, kann die Erweiterung
-[LSP4IJ](https://plugins.jetbrains.com/plugin/23257-lsp4ij) installiert werden.
-
-## Installation
-1. Installiere [LSP4IJ](https://plugins.jetbrains.com/plugin/23257-lsp4ij)
-2. Öffne den Language Server Tab
-3. Füge einen neuen Language-Server hinzu
-4. Vergebe einen Namen und füge folgenden Command hinzu: `java -jar "<path/to/LanguageServer.jar>`
-5. Füge unter Mappings -> File name patterns *.jav und Language ID java_tx hinzu
-6. öffne eine Datei mit Dateiendung .jav
-7. Fertig

-# Welcome to your VS Code Extension
+LSP-Client for Java-TX
-
-## What's in the folder
-
-* This folder contains all of the files necessary for your extension.
-* `package.json` - this is the manifest file in which you declare your extension and command.
-  * The sample plugin registers a command and defines its title and command name. With this information VS Code can show the command in the command palette. It doesn’t yet need to load the plugin.
-* `src/extension.ts` - this is the main file where you will provide the implementation of your command.
-  * The file exports one function, `activate`, which is called the very first time your extension is activated (in this case by executing the command). Inside the `activate` function we call `registerCommand`.
-  * We pass the function containing the implementation of the command as the second parameter to `registerCommand`.
-
-## Get up and running straight away
-
-* Press `F5` to open a new window with your extension loaded.
-* Run your command from the command palette by pressing (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and typing `Hello World`.
-* Set breakpoints in your code inside `src/extension.ts` to debug your extension.
-* Find output from your extension in the debug console.
-
-## Make changes
-
-* You can relaunch the extension from the debug toolbar after changing code in `src/extension.ts`.
-* You can also reload (`Ctrl+R` or `Cmd+R` on Mac) the VS Code window with your extension to load your changes.
-
-## Explore the API
-
-* You can open the full set of our API when you open the file `node_modules/@types/vscode/index.d.ts`.
-
-## Run tests
-
-* Install the [Extension Test Runner](https://marketplace.visualstudio.com/items?itemName=ms-vscode.extension-test-runner)
-* Run the "watch" task via the **Tasks: Run Task** command. Make sure this is running, or tests might not be discovered.
-* Open the Testing view from the activity bar and click the Run Test" button, or use the hotkey `Ctrl/Cmd + ; A`
-* See the output of the test result in the Test Results view.
-* Make changes to `src/test/extension.test.ts` or create new test files inside the `test` folder.
-  * The provided test runner will only consider files matching the name pattern `**.test.ts`.
-  * You can create folders inside the `test` folder to structure your tests any way you want.
-
-## Go further
-
-* [Follow UX guidelines](https://code.visualstudio.com/api/ux-guidelines/overview) to create extensions that seamlessly integrate with VS Code's native interface and patterns.
-* Reduce the extension size and improve the startup time by [bundling your extension](https://code.visualstudio.com/api/working-with-extensions/bundling-extension).
-* [Publish your extension](https://code.visualstudio.com/api/working-with-extensions/publishing-extension) on the VS Code extension marketplace.
-* Automate builds by setting up [Continuous Integration](https://code.visualstudio.com/api/working-with-extensions/continuous-integration).
-* Integrate to the [report issue](https://code.visualstudio.com/api/get-started/wrapping-up#issue-reporting) flow to get issue and feature requests reported by users.
