  - Build the DMG: `cd build && cpack`
  - Build the PKG: `cd build && cpack -G productbuild`
 
-#### Xcode
-
- - Install dependencies and clone xca as above
-   and additionally install the xcode app
- - `cmake -G Xcode
-
 ### Windows
 
 - Install the dependencies
   - Install Python for windows from the store or https://www.python.org/downloads/windows/
   - Install OpenSSL from here: https://slproweb.com/download/Win64OpenSSL-1_1_1m.msi and verify the sha256 from https://github.com/slproweb/opensslhashes/blob/master/win32_openssl_hashes.json
   - To install the Qt libraries, cmake and the MinGW compiler [aqtinstall](https://github.com/miurahr/aqtinstall) is used.
-  ```
-  pip3 install sphinx aqtinstall
-  ```
-  Add the PATH shown by pip to your PATH
-  ```
-  aqt install-qt windows desktop 5.15.2 win64\_mingw81
-  aqt install-tool windows desktop tools\_cmake qt.tools.cmake.win64
-  aqt install-tool windows desktop tools\_mingw qt.tools.win64\_mingw810
-  ```
-  If 7z is missing, install it from the store.

- - Clone: `git clone https://github.com/chris2511/xca.git`
- - Configure: `cmake -B build -G "MinGW Makefiles" xca`
- - Make: `cmake --build build -j5`
- - Build the MSI installer: `cd build && cpack`
-
-Of course VSCode may be used, too. The MSVC toolchain, however
-is no supported, yet.
+    Sphinx is used to generate the documentation
+    ```
+    pip3 install sphinx aqtinstall
+    ```
+  - Add the PATH shown by pip to your PATH
+  - Install Qt, cmake and the MinGW toolchain
+    ```
+    aqt install-qt windows desktop 5.15.2 win64_mingw81
+    aqt install-tool windows desktop tools\_cmake qt.tools.cmake.win64
