+brew install clang-format cppcheck make vcpkg
+
+```
+
+## Visual Studio Code extensions
+
+Suggested for a C++ stack
+
+```sh
+code --install-extension ms-vscode.cpptools-extension-pack
+code --install-extension ms-vscode.cmake-tools
+code --install-extension xaver.clang-format
+code --install-extension ryanluker.vscode-coverage-gutters
+code --install-extension NathanJ.cpp-tools-plugin
