 # Patterns
 
-SwiftUI tiling black and white patterns
+SwiftUI tiling black and white patterns.
+
+This project contains `Patterns`, which are built out of `Tiles` with a given
+`TileDesign`.
+
+It also includes a `TilePicker` that can be used to control the selected
+design.
+
+## Available Tile Designs
+
+The `TileDesign` enum contains the following patterns (shown in the image from
+top left to bottom right)
+
+![Image showing the included patterns]
+
+* `.grid`
+* `.dottedGrid`
+* `.stitch`
+* `.curvedTile`
+* `.brick`
+* `.tile`
+* `.shadowGrid`
+* `.circles`
+* `.trees`
+* `.shingles`
+* `.wicker`
+* `.rhombus`
+* `.balls`
+
+## Usage
+
+The `Pattern` view will tile the selected design in its frame. It has the
+following properties:
+
+* `design: TileDesign`: **required, @Binding**, which design to tile the frame with.
+* `pixelSize: CGFloat`: **defaults to 2.0**, the size of a pixel in the tile.
+* `foregroundColor: Color`: **defaults to `Color.black`**, the foreground color.
+* `backgroundColor: Color`: **defaults to `Color.white`**, the background color.
+
+```
+// Pattern using default settings
+Pattern(design: .constant(TileDesign.shadowGrid))
+
+// Pattern using overrides
+Pattern(design: $tileDesign, pixelSize: 4.0, foregroundColor: .pink, backgroundColor: .cyan)
+```
+
+## Using the PatternPicker
+
+The pattern picker view is intended to be used when you want to allow users to
+change the design of the pattern.
+
+* `selectedDesign: TileDesign`: **required, @Binding**, the current selected
+  tile design.
+* `selectedColor: Color`: **defaults to `Color.accentColor`**, the color of the
+  border around the selected tile design.
+
+It also has `pixelSize`, `foregroundColor`, and `backgroundColor` with the
+same effect as `Pattern` mentioned above
+
+
+```
+@State var design: TileDesign = .brick
+@State var shouldShowPatternPicker = false
+
+...
+
+Pattern(design: $pattern)
+  .frame(width: 32.0).border(.black)
+  .onTapGesture {
+    shouldShowPatternPicker = !shouldShowPatternPicker;
+  }
+  .popover(isPresented: $shouldShowPatternPicker) {
+    PatternPicker(selectedDesign: $design)
+  }
+  .onChange(of: pattern) { _ in
+    shouldShowPatternPicker = false;
+  }
+```
