 # Terra Signature
 
-The terra-signature component provides users a way to define a signature with a series of line segments.
-The component can define line width, line color, and optionally display a signature if the line segments have
-already been recorded. Exiting the canvas then re-entering continues the drawing, as long as the pointer does not exit the confines of the browser. For mouse usage, only left click drawing is enabled.
+The terra-signature component is used to digitally validate or acknowledge files or documents such as PDF documents, online forms, or specialized e-signature software.
+- For mouse usage, only left-click drawing is enabled, and can continue the drawing with a series of line segments as long as the pointer does not exit the confines of the browser. 
+- The Terra Signature component has the ability to define line width, and line color, and optionally display a signature if the line segments used in the signature have already been recorded.
+- For keyboard usage, consumers can provide their signature by typing, drawing, or inserting an image file with their name. Ensuring the keyboard navigation follows a logical tab order, and provides the instructions and cues necessary to complete the same action.
+- The Terra Signature component supports resizing to 400% and supports reflow when the viewport is resized to 320x256 px without loss of information or function.
