 # FontPicker
 
-A description of this package.
+A Font Picker in a similar style to Apple's Color Picker, providing a means of choosing a font from the available UIFont familyNames. I'm not 100% sure that all of these font names work in SwiftUI, but they seem to.

+
+## Installation
+
+### Swift Package Manager
+
+In Xcode:
+* File ⭢ Swift Packages ⭢ Add Package Dependency...
+* Use the URL https://github.com/franklynw/FontPicker
+
+
+## Example
+
+> **NB:** All examples require `import FontPicker` at the top of the source file
+
+It can be used directly as a view, which offers the full range of customisation options -
+
+```swift
+var body: some View {
+
+    FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
+        .additionalFontNames(["MySpecialFont"])
+        .excludedFontNames(["Marker Felt"])
+        .backgroundColor(viewModel.fontPickerBackgroundColor)
+}
+```
+
+or as a modifier, which presents the default font picker (with no customisation options) -
+
+```swift
+var body: some View {
+
+    MyView {
+
+    }
+    .fontPicker(isPresented: $isFontPickerPresented, Binding: $viewModel.selectedFont) {
+        // your view here
+    }
+}
+```
+
+### Specify the fonts you want to be shown
+
+If you use this modifier, it will only show the fonts you specify
+
+```swift
+FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
+    .fontNames(viewModel.allTheBestFonts)
+```
+
+### Specify the fonts you'd like to add to the default list
+
+This will show all of the available system fonts, plus any you pass in here
+
+```swift
+FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
+    .additionalFontNames(viewModel.myUniqueFonts)
+```
+
+### Specify the fonts you'd like to not be shown
+
+This will show all of the available system fonts, minus any you pass in here
+
+```swift
+FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
+    .excludedFontNames(viewModel.rubbishFonts)
+```
+
+### Disable the automatic "dismiss on selection" functionality
+
+This might be necessary if you have (eg) a preview visible above the picker, where you can see how your selected font looks - the user can then decide when to dismiss the picker
+
+```swift
+FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
+    .disableDismissOnSelection
+```
+
+### Set the picker's background colour
+
+```swift
+FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
+    .backgroundColor(.lightGray)
+```
