+# US Universal Keyboard Layout
+A native keyboard layout for Windows that enables simple typing of complex characters.
+## Applications
+The layout supports a wide range of use cases. The various new modifier keys can be held to access an array of supplementary characters, while the Compose key (Right-Ctrl) can be pressed as the beginning of a sequence to combine standard characters into exotic ones.
+### International
+Improving upon the US International layout, the Compose (Right-Ctrl) and AltGR (Right-Alt) keys can be used to directly access a multitude of international characters, such as ligatures, accented vowels, and foreign currency symbols.
+### Mathematics
+The Compose key also allows input of various mathematical symbols and constants; integrals, inequalities, and other operators are all supported. Additionally, the Application key allows access to Greek characters, and CapsLock enables super/subscripts.

+### Normal Stuff
+Even with so many features, this layout tries to stay out of your way during everyday typing. The only keys with different behaviors than in the standard US layout are:
+- CapsLock now enables super/subscripts instead of capitals.
+- The keys between Spacebar and Right-Ctrl have been repurposed as modifier keys.
+- NumLock is now a completely separate, togglable modifier key that enables boldness. It's recommended to configure Windows to start with NumLock enabled while using this layout. Alternatively, if you keep at least one other keyboard layout equipped, you can switch to it with WindowsKey+Spacebar for the rare occasion where NumLock needs to be toggled. Also worth noting is that you can access the 'off' functionality of the NumPad even with NumLock enabled by holding Shift while pressing a NumPad key.
