+> [!NOTE]

+> If you switch between Neovim and VSCode regularly, you probably want to use VSCode's directory, which is `~/AppData/Roaming/Code/User/globalStorage/sumneko.lua` on Windows and `~/.config/Code/User/globalStorage/sumneko.lua` on Linux

+> [!WARNING]
+>
+> The VSCode extension [currently does not automatically install addons](https://github.com/LuaLS/vscode-lua/issues/159). If a user that does not have this addon installed already opens a project that has this `.luarc.json` present, they will have to open the Addon Manager and click Disable and Enable on this addon for it to install the addon properly.
