 ### Use
 
-The app presents four tabs `Settings`, `Physical Strip`, `Virtual Strip` and `Buses`. Navigate between the tabs with `Control + TAB` and `Control + SHIFT + TAB`.
+#### `Tabs`
+
+The app presents four tabs `Settings`, `Physical Strip`, `Virtual Strip` and `Buses`. Navigate between the tabs with `Control + TAB` and `Control + SHIFT + TAB` or once focused on any tab, `Left` and `Right` arrow keys.
 
 All controls within the tabs may be navigated between using `TAB`.
 
+#### `Settings`
+
 The following controls offer context menus accessed by pressing `SPACE` or `ENTER`:
 
 - Hardware In
 - Hardware Out
 - Patch Composite
 
+Press `ESCAPE` to exit any context menu.
+
 All other buttons can be triggered by pressing `SPACE` or `ENTER`.
 
 To adjust Patch Asio Inputs to Strips and Patch Insert values use `UP` and `DOWN` arrows when in focus.
 
+To access Advanced Settings you may press the Advanced Settings button or use `Control + A` when in the `Settings` tab.
+
+#### `Strip/Bus`
+
 To rename a strip/bus channel navigate to the relevant tab, then press `F2`. This will open a popup window where you can set the channel index (with a spinbox) and set the new label using a text input box.
+
 Pressing the `OK` button with an empty text input will clear the label. In this case the label will be read as a default value for that channel. For example, if the leftmost Strip label were cleared, the screen reader will now read `Hardware Input 1`.
+
 Pressing `Cancel` will close the popup window with no affect on the label.
 
+#### `Menu`
+
 A single menu item `Voicemeeter` can be opened using `Alt` and then `v`. The menu allows you to:

+# Software Specification
+
+## Description
+
+A remote control utility for Voicemeeter designed to be used with the NVDA screen reader.
+
+## Requirements
+
+#### Functional Goals
+
+- Parameter updates caused by user input should be read back to the user via the screen reader.
+- When focusing a control the current value for that control should be read back to the user.
+- The application should scale correctly according to each kind of Voicemeeter (basic, banana, potato). This means the following:
+  - Correct number of strips/buses.
+  - Correct number of bus assignments for each strip.
+  - Where certain controls are valid for one kind they may not be for another.
+- Where possible set limits on data entry and keep controls appropriate for the type of parameter.
+
+#### Accessibility Goals
+
+- Every control must be usable with a keyboard.
+- Navigation around the application must be doable with a keyboard.
+- Should use standard Windows controls only.
+
+## Limitations
+
+- May not cover 100% of the Voicemeeter GUI, for example the many EQ parameters.
+- Only designed to work with the NVDA screen reader. Other screen readers not supported.
+- Only the main Voicemeeter GUI supported by this application. No support for Matrix or other Voicemeeter products.
+- Runs on Python version 3.10 or greater.
