+I am more than happy helping you install Linux on your machine.
 
 ## Setup

+I recommend using docker and VS Code for setup.
-If this is not your preferred Setup, take a look in the Docker file for the dependencies.
+Also check out the recommended extensions in the Docker section.
+If you prefer to work from Linux or Mac OS X, check the Dockerfile for dependencies.
 
-Also we do not support the usage of Windows, Linux is free of charge so get a copy.
+Also make sure to have a LLVM13 install.
 
-### Setting Docker up
+### Installing LLVM 13 on Mac OS X
+
+On Darwin you can install LLVM 13 with [Homebrew](https://brew.sh/):
+
+```bash
+brew install llvm@13
+```
+
+If you already have an older version of LLVM installed, you can upgrade it to
+LLVM 13 like this:
+
+```bash
+brew upgrade llvm
+```
+
+Once the installation (or upgrade) is complete, all the required header files,
+libraries and tools will be located in `/usr/local/opt/llvm/`.
+
+### Installing LLVM 13 on Ubuntu
+
+On Ubuntu Bionic, you can [install modern
+LLVM](https://blog.kowalczyk.info/article/k/how-to-install-latest-clang-6.0-on-ubuntu-16.04-xenial-wsl.html)
+from the official [repository](http://apt.llvm.org/):
+
+```bash
+wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
+sudo apt-add-repository "deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-13 main"
+sudo apt-get update
+sudo apt-get install -y llvm-13 llvm-13-dev llvm-13-tools clang-13
+```
+
+This will install all the required header files, libraries and tools in
+`/usr/lib/llvm-13/`.
+
+### Building LLVM 13 From Sources
+
+Building from sources can be slow and tricky to debug. It is not necessary, but
+might be your preferred way of obtaining LLVM 13. The following steps will work
+on Linux and Mac OS X:
+
+```bash
+git clone https://github.com/llvm/llvm-project.git
+cd llvm-project
+git checkout release/13.x
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD=host -DLLVM_ENABLE_PROJECTS=clang <llvm-project/root/dir>/llvm/
+cmake --build .
+```
+
+For more details read the [official
+documentation](https://llvm.org/docs/CMake.html).
