 - Copy the DLLs into the top-level directory of either Plugins folder

-- Copy the file `parks-submenus.dat` anywhere into your Plugins folder.
+- Copy the file `submenu-essentials.dat` and optionally the individual submenu files anywhere into your Plugins folder.
+  You may skip installing an optional submenu if it contains neither Flora nor any sub-submenus.
+  In that case, the buildings of that submenu will appear in the default top-level menu instead.
 
 ## Troubleshooting
 
 The plugin should write a `.log` file in the folder containing the plugin.
 The log contains status information for the most recent run of the plugin.
 
-If the parks submenus appear empty in the game,
-there is a conflicting mod in your Plugins that overwrites properties of the Maxis parks.
-Check if a submenu-compatible version of that mod is available
-or move the `parks-submenus.dat` to a folder loading later.
-In any case, the DLL can still be used as a dependency for other plugins.
+If no `.log` file is written, the DLL failed to load.
+In this case, make sure the [Microsoft Visual C++ 2022+ x86 Redistributable](https://aka.ms/vs/17/release/vc_redist.x86.exe) is installed.

+Others remain empty (and therefore hidden) until you install plugins that have been updated for submenu functionality.

+Wether an item appears in a submenu can be explicit or implicit:
+explicit if the item was modified to use a particular submenu;
+implicit if the item belongs to a category associated with a submenu marked with `*`.
