+## AWM Features
+AWM comes with a couple different features, notably the WM itself.
+- Window Manager – the core functionality of AWM. This goes without say that it's
+the biggest and primary feature of AWM (AWM does what it says on the tin). It
+supports up to four layouts of Alacritty instances, but does not organise new
+Alacritty windows.
+- Fullscreen Terminals – AWM supports toggling Alacritty terminals into fullscreen.
+This doesn't hide the taskbar, nor consume the entire desktop work area, but it does
+take up majority of the desktop. This allows for greater focus and work area within
+a selected terminal, hiding other windows behind. Run `awm --fullscreen` to toggle
+this behaviour. When exiting fullscreen, the window will be placed back in its
+original tiled configuration with other Alacritty instances.

 ## Known Issues & Limitations
+### With AWM Itself
 As discussed in the note above, and elsewhere, AWM **does not** add event hooks
 to the system, or listen to any event hooks that might trigger when an Alacritty
 window is created or destroyed. For this reason, AWM must be manually told when

 currently unknown why this bug exists without `-O3`, and doesn't with the flag,
 but it can be easily avoided with the `-O3` flag using `g++`. A future patch may
 be applied to this in the future.
+### Due to Alacritty
+It seems that there might be a few issues as a result of Alacritty (or perhaps
+within the dependencies it uses). Firstly, after some more in-depth experimentation
+of the Win32 API, it seems as though Alacritty does not set the correct flags on a
+window defined in the API to indicate that a window is minimised. This makes it
+impossible for AWM to correctly filter non-viewable terminals out of organisation.
+### Shared & Due to Knowledge
+When a new window is created in Alacritty, it simply spawns a new Console Host
+program (`conhost.exe`). This is specific to Windows and whose purpose is out of
+the scope of this document. However, it means that a single `alacritty.exe` program
+exists with multiple conhost applications running PowerShell. From experiments,
+you can't simply change the window's context of conhost apps without causing some
+mischievious behaviour. A conhost app will refer back to Alacritty in some way,
+but it's not possible to refer to Alacritty for changing the context of a window.
+Or at least, it's not possible with the current knowledge of the project. Alacritty
+might be behaving exactly as intended of Windows' apps, but as it stands, AWM
+cannot organise new windows of Alacritty, only new instances.
