+## Introduction
+
+This is a basic ViewPort application for the Flipper Zero. The goal of this project is to use it as a starting point for other applications. When creating a UI for the Flipper Zero, you can choose from three techniques:
+
+- "ViewPort" (single view that does all the rendering & input handling)
+- "ViewDispatcher" (multiple views, single back button is handled for you)
+- "SceneManager" (multiple views, back button history is handled for you)
 
 ## Installation Directions
+
 This project is intended to be overlayed on top of an existing firmware repo.
+
 - Clone, Build & Deploy an existing flipper zero firmware repo. See this [tutorial](/firmware/updating/README.md) for updating firmware.
 - Copy the "basic_demo" [folder](..) to the \applications\plugins\basic_demo folder in your firmware.
 - Build & deploy the firmware. See this [tutorial](/firmware/updating/README.md) for updating firmware.
 - NOTE: You can also extract the basic_demo.FAP from resources.tar file and use qFlipper to copy the file to the SD Card/apps/Misc folder.
 
-
 ## Running the updated firmware
+
 These directions assume you are starting at the flipper desktop. If not, please press the back button until you are at the desktop.
 
 - Press the OK button on the flipper to pull up the main menu.
 - Choose "Applications" from the menu.
 - Choose "Misc" from the sub-menu.
-- Choose "Basic Demo"
+- Choose "Basic Viewport Demo"
 
-- The flipper should say "Basic Demo".
+- The flipper should say "Basic Viewport Demo".
 
 - Press the BACK button to exit.
