+        GHC versions you can run the following commands:
+          stack config set install-ghc false --global
+          stack config set system-ghc  true  --global
+        
+        On windows, you may find the following config options useful too:
+          skip-msys, extra-path, extra-include-dirs, extra-lib-dirs
+
+        Also check out: https://docs.haskellstack.org/en/stable/yaml_configuration
+
+        !!! Additionally, you should upgrade stack only through ghcup and not use 'stack upgrade' !!!
