+
+FlutterQuill is a rich text editor and a [Quill] component for [Flutter].
+
+This library is a WYSIWYG editor built for the modern mobile platform, with web compatibility under development. You can join our [Slack Group] for discussion.
+
+Demo App: https://bulletjournal.us/home/index.html
+
+Pub: https://pub.dev/packages/flutter_quill
+
+## Usage
+
+See the `example` directory for a minimal example of how to use FlutterQuill.  You typically just need to instantiate a controller:
+
+```
+QuillController _controller = QuillController.basic();
+```
+
+and then embed the toolbar and the editor, within your app.  For example:
+
+```dart
+Column(
+  children: [
+    QuillToolbar.basic(controller: _controller),
+    Expanded(
+      child: Container(
+        child: QuillEditor.basic(
+          controller: _controller,
+          readOnly: false, // true for view only mode
+        ),
+      ),
+    )
+  ],
+)
+```
+Check out [Sample Page] for advanced usage.
+
+## Input / Output
 
 This library uses [Quill] as an internal data format.
-Use `_controller.document.toDelta()` to extract it or use `_controller.document.toPlainText()` for plain text.
-
-Default branch `master` is on channel `master`. To use channel `stable`, switch to branch `stable`.
-Branch `master` on channel `master` supports web. To run the app on web do the following:
-1) Change flutter channel to master using `flutter channel master`, followed by `flutter upgrade`.
-2) Enable web using `flutter config --enable-web` and restart the IDE.
-3) Upon successful execution of step 1 and 2 you should see `Chrome` as one of the devices which you run `flutter devices`.
-4) Run the app.
-
-For web development, [ReactQuill] is recommended to use for compatibility.

-  
+
+* Use `_controller.document.toDelta()` to extract the deltas.
+* Use `_controller.document.toPlainText()` to extract plain text.
+
+FlutterQuill provides some JSON serialisation support, so that you can save and open documents.  To save a document as JSON, do something like the following:
+
+```
+var json = jsonEncode(_controller.document.toDelta().toJson());
+```
+
+You can then write this to storage.
+
+To open a FlutterQuill editor with an existing JSON representation that you've previously stored, you can do something like this:
+
+```
+var myJSON = jsonDecode(incomingJSONText);
+_controller = QuillController(
+          document: Document.fromJson(myJSON),
+          selection: TextSelection.collapsed(offset: 0));
+```
+
+## Configuration
+
+The `QuillToolbar` class lets you customise which formatting options are available.
+[Sample Page] provides sample code for advanced usage and configuration.
+
+## Web
+
+For web development, use `flutter config --enable-web` for flutter and use [ReactQuill] for React.
+
+It is required to provide `EmbedBuilder`, e.g. [defaultEmbedBuilderWeb](https://github.com/singerdmx/flutter-quill/blob/master/example/lib/universal_ui/universal_ui.dart#L28).
+Also it is required to provide `webImagePickImpl`, e.g. [Sample Page](https://github.com/singerdmx/flutter-quill/blob/master/example/lib/pages/home_page.dart#L212).
+
+## Desktop
+
+It is required to provide `filePickImpl` for toolbar image button, e.g. [Sample Page](https://github.com/singerdmx/flutter-quill/blob/master/example/lib/pages/home_page.dart#L192).
+
+## Custom Size Image for Mobile
+
+Define `mobileWidth`, `mobileHeight`, `mobileMargin`, `mobileAlignment` as follows:
+```
+{
+      "insert": {
+         "image": "https://user-images.githubusercontent.com/122956/72955931-ccc07900-3d52-11ea-89b1-d468a6e2aa2b.png"
+      },
+      "attributes":{
+         "style":"mobileWidth: 50; mobileHeight: 50; mobileMargin: 10; mobileAlignment: topLeft"
+      }
+}
+```
+
