-It boils down to this: A user selects a color and clicks on pixels to paint them with the selected color.
+A user should be able to click on a color from their palette, allowing them to then be able click on individual pixels in a canvas area to paint them.
 
-Here's the order of steps that I would implement:
+Here's an example of a workflow that could be implemented:
 
-1. Get 10 or so small divs on the screen
-2. Add an event listener to each so that when I click on a pixel it turns red
-3. Add a color palette div with 2 colors(red and purple)which allows the user to set the current "paintbrush" color instead of it always being set to red
-4. Add the rest of the standard rainbow colors to the color palette
-5. Add enough divs to fill up the entire screen
+1. Create 10 or so small, white, square divs to start making a pixel canvas.
+2. Add an event listener to each so that when clicked on, that div's background turns red.
+3. Add a couple more square divs to make a palette. Begin with 2 background colors (red and blue), which allow the user to set the current "brush" color, instead of a pixel's background always turning red.
+4. Add the rest of the standard colors to your palette as well as an eraser. (Red, Orange, Yellow, Green, Blue, Purple, Black, Brown, White, etc.)
+5. Add more divs to expand the size of your pixel canvas.
