-## Building
+## Abhängigkeiten & Bauen
-
-### Prerequisites
-
-- CMake ≥ 3.16
-- Qt6 (Widgets module)
-- A C++17-capable compiler (GCC, Clang, MSVC)
 
 ### Linux
 
+**Ubuntu / Debian:**
 ```bash
+sudo apt install cmake ninja-build qt6-base-dev qt6-base-dev-tools
+```
+
+**Arch / Manjaro:**
+```bash
+sudo pacman -S cmake ninja qt6-base
+```
+
+**Bauen:**
+```bash
+cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
+cmake --build build
+./build/BareCode
+```
+
+**Installieren:**
+```bash
+sudo cmake --install build
+```
+
+---
+
+### Windows
+
+**Abhängigkeiten:**
+- [Qt6](https://www.qt.io/download) — Komponenten: Qt6 Base, Qt6 Concurrent
+- CMake ≥ 3.16
+- Visual Studio 2019 oder neuer
+
+```bat
+cmake -B build -G "Visual Studio 17 2022" -A x64
+cmake --build build --config Release
+```
+
+---
+
+### Haiku
+
+```bash
+pkgman install qt6_base qt6_base_devel
 cmake -B build -DCMAKE_BUILD_TYPE=Release
 cmake --build build -j$(nproc)
 ./build/BareCode
 ```
 
-### Windows (Visual Studio)
+> Getestet auf Haiku R1/beta5.
-
-```bat
-cmake -B build -G "Visual Studio 17 2022" -A x64
-cmake --build build --config Release
-build\Release\BareCode.exe
-```
-
-### Windows (MinGW)
-
-```bat
-cmake -B build -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Release
-cmake --build build
-build\BareCode.exe
-```
 
 ---
 
-## Extending BareCode
+## Neue Sprache hinzufügen
 
-### Adding a new syntax highlighter
+1. Subklasse von `SyntaxHighlighter` in `src/highlighter/` erstellen
-
+2. `m_rules` im Konstruktor befüllen (siehe `CppHighlighter` als Vorlage)
-1. Create a subclass of `SyntaxHighlighter` in `src/highlighter/`.
+3. Dateiendung in `HighlighterFactory.cpp` registrieren
-2. Populate `m_rules` in the constructor (see `CppHighlighter` as a template).
-3. Register the file extension(s) in `HighlighterFactory.cpp`.
-
-No other files need to change.
-
-### Adding a new panel / plugin
-
-1. Implement the `IPlugin` interface from `src/core/IPlugin.h`.
-2. Create a `QWidget`-derived class for the UI.
-3. Instantiate and wire it up in `MainWindow`.
