 # Windows Desktop Duplication Tool
 
-This is a little tool for live coding presentations.
+This is a nifty tool to host live coding in presentations.
 
-I like to see the IDE on my laptop screen. But I don't want to duplicate the screen, so I can see my private notes.
+You have your IDE and private notes on your main screen.
+The tool only captures the code portion of this screen and shows it fullscreen on your presentation monitor or projector.

-I could not find such a tool, so I created this.
+Personally I use this tool to host C++ usergroup meetings, client meetings and professional C++ trainings.
 
 
 ## Features
 
-By default the primary screen is duplicated to a window.
+By top left part of the primary screen is duplicated to a window on the right part of the same screen.
 
 Interactions:
 
 * Move the window whereever you need it. Beamers for live coding and presentations.
-* You can resize the window as you like. This changes the portion of the screen that is visible.
 * Double Left Mouseclick maximizes the window.
-* Maximized window looses the window frame. Ideal for presentations.
-* pass:[<kbd>Ctrl</kbd>] + pass:[<kbd>Mousewheel ↕</kbd>/<kbd>+</kbd>/<kbd>-</kbd>] allows you to zoom
-* pass:[<kbd>Ctrl</kbd><kbd>Shift</kbd>] + pass:[<kbd>Mousewheel ↕</kbd>] zooms in smaller steps
-* pass:[<kbd>Ctrl</kbd> + <kbd>0</kbd>] reset zoom to 1:1
-* pass:[<kbd>Shift</kbd>] + pass:[<kbd>Left Mouse Button</kbd>] + pass:[<kbd>Dragging ⇔⇕</kbd>] allows you to move the visible portion
-* pass:[2×<kbd>Right Mouse Button</kbd>] + [Focus other Window] will position and resize the other window into the mirrored area. Not all windows will like this.
-* pass:[<kbd>Shift</kbd> + <kbd>←</kbd>/<kbd>↑</kbd>/<kbd>→</kbd>/<kbd>↓</kbd>] aligns the mirrored image to the border
-* pass:[<kbd>Shift</kbd> + <kbd>Right Mouse Button</kbd>] toggle a visualisation of the captured area
-* pass:[<kbd>Ctrl</kbd> + <kbd>P</kbd>] toggle pause. Freezes the image.
+** The entire screen is now mirroring (no window frame)
+** We prevent Windows from going to sleep mode in this presentation mode
+* The Zoom also changes captured area.
+** pass:[<kbd>Ctrl</kbd>] + pass:[<kbd>Mousewheel ↕</kbd>/<kbd>+</kbd>/<kbd>-</kbd>] allows you to zoom
+** pass:[<kbd>Ctrl</kbd><kbd>Shift</kbd>] + pass:[<kbd>Mousewheel ↕</kbd>] zooms in smaller steps
+** pass:[<kbd>Ctrl</kbd> + <kbd>0</kbd>] reset zoom to 1:1
+* Moving the captured area.
+** pass:[<kbd>Shift</kbd>] + pass:[<kbd>Left Mouse Button</kbd>] + pass:[<kbd>Dragging ⇔⇕</kbd>] allows you to move the visible portion
+** pass:[<kbd>Shift</kbd> + <kbd>←</kbd>/<kbd>↑</kbd>/<kbd>→</kbd>/<kbd>↓</kbd>] aligns the mirrored image to the border
+* Move Window into captured area.
+** pass:[2×<kbd>Right Mouse Button</kbd>] + [Focus other Window] will position and resize the other window into the mirrored area. Not all windows will like this.
+* Interactions:
+** Note: You can hover over the window icon in the taskbar and use the buttons there.
+** pass:[<kbd>Shift</kbd> + <kbd>Right Mouse Button</kbd>] toggle a visualisation of the captured area
+** pass:[<kbd>Ctrl</kbd> + <kbd>P</kbd>] toggle pause. Freezes the image.
 
 The tool is optimized to be very response and save CPU time.
