+# 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
