+
+Is a collection of Material Design compliant widgets for use with,
+`Kivy cross-platform graphical framework <http://kivy.org/#home>`_
+a framework for cross-platform, touch-enabled graphical applications.
+The project's goal is to approximate Google's `Material Design spec
+<https://material.io/design/introduction>`_ as close as possible without
+sacrificing ease of use or application performance.
+
+This library is a fork of the `KivyMD project
+<https://gitlab.com/kivymd/KivyMD>`_ the author of which stopped supporting
+this project three years ago. We found the strength and brought this project
+to a new level. Currently we're in **beta** status, so things are changing
+all the time and we cannot promise any kind of API stability.
+However it is safe to vendor now and make use of what's currently available.
+
+Join the project! Just fork the project, branch out and submit a pull request
+when your patch is ready. If any changes are necessary, we'll guide you
+through the steps that need to be done via PR comments or access to your for
+may be requested to outright submit them. If you wish to become a project
+developer (permission to create branches on the project without forking for
+easier collaboration), have at least one PR approved and ask for it.
+If you contribute regularly to the project the role may be offered to you
+without asking too.

+RouletteScrollEffect
+===================
+
+This is a subclass of `kivy.effects.ScrollEffect` that simulates the
+motion of a roulette, or a notched wheel (think Wheel of Fortune). It is
+primarily designed for emulating the effect of the iOS and android date pickers.
+
+Usage
+-----
+
+Here's an example of using `RouletteScrollEffect` for a `kivy.uix.scrollview.ScrollView`:
+
+```python
+    from kivy.uix.gridlayout import GridLayout
+    from kivy.uix.button import Button
+    from kivy.uix.scrollview import ScrollView
+
+    # Preparing a `GridLayout` inside a `ScrollView`.
+    layout = GridLayout(cols=1, padding=10, size_hint=(None, None), width=500)
+    layout.bind(minimum_height=layout.setter('height'))
+
+    for i in range(30):
+        btn = Button(text=str(i), size=(480, 40), size_hint=(None, None))
+        layout.add_widget(btn)
+
+    root = ScrollView(
+        size_hint=(None, None),
+        size=(500, 320),
+        pos_hint={'center_x': .5, 'center_y': .5},
+        do_scroll_x=False,
+        )
+    root.add_widget(layout)
+
+    # Preparation complete. Now add the new scroll effect.
+    root.effect_y = RouletteScrollEffect(anchor=20, interval=40)
+    runTouchApp(root)
+```
+
+Here the `ScrollView` scrolls through a series of buttons with height `40`. We then attached a `RouletteScrollEffect` with interval 40,
+corresponding to the button heights. This allows the scrolling to stop at
+the same offset no matter where it stops. The `RouletteScrollEffect.anchor`
+adjusts this offset.
+
+Customizations
+--------------
+
+Other settings that can be played with include:
+
+- `RouletteScrollEffect.pull_duration`
+- `RouletteScrollEffect.coasting_alpha`
+- `RouletteScrollEffect.pull_back_velocity`
+- `RouletteScrollEffect.terminal_velocity`
+
+See their module documentations for details.
+
+`RouletteScrollEffect` has one event ``on_coasted_to_stop`` that
+is fired when the roulette stops, "making a selection". It can be listened to
+for handling or cleaning up choice making.

+stiffscroll
+===========
+
+A ScrollEffect for use with a Kivy ScrollView. It makes scrolling more
+laborious as you reach the edge of the scrollable area.
+
+A ScrollView constructed with StiffScrollEffect,
+eg. ScrollView(effect_cls=StiffScrollEffect), will get harder to
+scroll as you get nearer to its edges. You can scroll all the way to
+the edge if you want to, but it will take more finger-movement than
+usual.
+
+Unlike DampedScrollEffect, it is impossible to overscroll with
+StiffScrollEffect. That means you cannot push the contents of the
+ScrollView far enough to see what's beneath them. This is appropriate
+if the ScrollView contains, eg., a background image, like a desktop
+wallpaper. Overscrolling may give the impression that there is some
+reason to overscroll, even if just to take a peek beneath, and that
+impression may be misleading.

+KivyToast
+========
+
+A package for working with messages like Toast on Android. It is intended for use in applications written using the Kivy framework.
+
+This package is an improved version of the package https://github.com/knappador/kivy-toaster in which human toasts are written, written on Kivy.
+
+<img src="https://raw.githubusercontent.com/HeaTTheatR/KivyToast/master/Screenshot.png" align="center"/>
+
+The package modules are written using the framework for cross-platform development of <Kivy>.
+Information about the <Kivy> framework is available at http://kivy.org.
+
+An example of usage (note that with this import the native implementation of toasts will be used for the Android platform and implementation on Kivy for others:
+
+```python
+from toast import toast
+
+...
+
+# And then in the code, toasts are available
+# by calling the toast function:
+toast ('Your message')
+```
+
+To force the Kivy implementation on the Android platform, use the import of the form:
+
+```python
+from toast.kivytoast import toast
+```
+
