 ### Installation
 
-Copy/symlink `gui_master_framework_42.lua` to your Spring installation's `LuaUI/Widgets/` folder, and the `MasterFramework 42` folder to your `LuaUI/` folder, forming the path `LuaUI/MasterFramework 42/`.
+Copy/symlink `gui_master_framework_dev.lua` to your Spring installation's `LuaUI/Widgets/` folder, and the `MasterFramework Dev` folder to your `LuaUI/` folder, forming the path `LuaUI/MasterFramework Dev/`.
 
 As a result, your LuaUI directory should look like this:
 ```
 LuaUI/
-    MasterFramework 42/
+    MasterFramework Dev/
     Widgets/
-        gui_master_framework_42.lua
+        gui_master_framework_dev.lua
         ...
     ...
 ```
 
-Once installed, make sure you enable `MasterBel2's GUI Framework (42)` in Widget Selector. See [below](#Using-MasterFramework-to-build-your-UI) for how to use MasterFramework in your project.

 ### Importing MasterFramework
 
-MasterFramework supports multiple installed versions, available in the table `WG.MasterFramework` after the widget handler calls `widget:Initialize()` on the framework.
-The framework version number is the table key for the instance of MasterFramework; e.g. MasterFramework 42 can be accessed via `WG.MasterFramework[42]`.
+MasterFramework supports multiple installed versions, available in the table `WG` after the widget handler calls `widget:Initialize()` on the framework. 
+`MasterFramework Dev` is stored under `WG["MasterFramework Dev"]`.

-- The global environment (also the `framework` entry in the global environment) refers to the framework itself, that is registered in `WG.MasterFramework[42]`. 
+- The global environment (also the `framework` entry in the global environment) refers to the framework itself, that is registered in `WG["MasterFramework Dev]"`. 
 - A table `Internal` is provided in the global environment during framework initialisation only; this should be cached if needed. Post initialisation, it is removed from the global environment, to restrict access to users of the framework.
 - A table `Include` is provided in the global environment during framework initialisation only; this provides access to a portion of the standard global environment. This is also removed post-initialisation, to reduce unneccessary clutter.
 - Code is loaded in an unpredictable order; avoid top-level code in these files if at all possible. Instead, provide any necessary initialisation in [https://github.com/MasterBel2/Master-GUI-Framework/tree/main/gui_master_framework_42.lua] after the contents of [https://github.com/MasterBel2/Master-GUI-Framework/tree/main/MasterFramework%2042] have been loaded.
