+## Overview
 
-## Styling
+Klavier is primarily a visual keyboard library. While it can be easily connected to a sound engine for playback, its 
+primary purpose is displaying the current state of the keyboard at a given moment, and notifying the consumer about changes
+to the states when keys are played or released.
 
-### Layout
-By default, Klavier is responsive takes up the full width of its parent container. This can be changed by using a combination of `width`, `height`, and `blackKeyHeight` props. 
+## Interactivity
 
-### Appearance
-The visual appearance of the keyboard can be customized by specifying custom components for the black and white keys. This enables styling the keyboard with any approach.
+Klavier is interactive by default. It supports user input via computer keyboard, mouse, and touch.
+Interactivity can be completely or partially disabled.
+
+### Disabling interactivity
+```tsx
+<Klavier interactive={false} />
+```
+
+### Selective interactivity
+`interactive` prop can be provided with an object to selectively enable/disable input, e.g. only allow input from mouse:
+```tsx
+<Klavier interactive={{ mouse: true }} />
+```
+**Note:** When using object notation, omitted properties are set to false.
+
+## Customizing the size
+By default, Klavier is responsive takes up the full width of its parent container. This can be changed by using a 
+combination of `width`, `height`, and `blackKeyHeight` props. Those attributes accept any valid CSS values. 
+
+### Fixed width:
+```tsx
+<Klavier width="50vw" />
+```
+
+### Fixed width and height:
+```tsx
+<Klavier width="800px" height="80px" />
+```
+
+### Reducing the height in responsive mode
+Because height should be relative to the width of the keyboard, specifying a fixed height without a fixed width is not 
+recommended, as it will the instrument to widen/shrink based on the viewport size. Instead, you can utilize the CSS 
+`aspect-ratio` on the parent:
+```tsx
+<div style={{ aspectRatio: '8 / 1' }}>
+  <Klavier width="100%" height="100%"/>
+</div>
+```
+
+## Appearance
+
+### Styling keys
+
+Klavier intentionally ships with absolutely minimal styling. The appearance of the keyboard can be customized by specifying custom components for the black and white keys. 
+This enables changing the look of the keyboard with the approach of your choice.
 
 ```tsx
 const CustomBlackKey = ({ active, note }) => { return <div /> }

 **Important:** avoid defining components directly in the prop object, as it can cause performance issues.
+
+## Custom labels
+
+`components` can also be used to render custom labels on keys, whether it's the octave number, pitch name, or a keyboard 
+shortcut. As with keys, it requires a custom React component. The component will be injected with necessary note information.
+```tsx
+const CustomLabel = ({ active, note, midiC0, keyboardShortcut }) => {
+  return // Your custom label
+}
+
+<Klavier components={{ label: CustomLabel }}
