+# Progress Indicators
+The MDC Progress Indicator component exposes common foundation and component interfaces for a progress indicator. Components that implement these interfaces include [linear progress](https://github.com/material-components/material-components-web/tree/master/packages/mdc-linear-progress) and circular progress (WIP).
+[Material Design progress & activity requirements](https://material.io/go/design-progress-indicators).
+
+## Installation
+
+```
+npm install @material/progress-indicator
+```
+
+## Basic Usage
+
+### MDCProgressIndicatorFoundation API
+
+MDC Progress Indicator Foundation exposes the following methods:
+
+| Method Signature | Description |
+| --- | --- |
+| `setDeterminate(value: boolean) => void` | Toggles the component between the determinate and indeterminate state. |
+| `setProgress(value: number) => void` | Sets the progress to this value. Value should be between [0, 1]. |
+| `open() => void` | Puts the component in the open state. |
+| `close() => void` | Puts the component in the closed state. |
+
+### MDCProgressIndicator Component API
+
+MDC Progress Indicator exposes the following API:
+
+| Method Signature | Description |
+| --- | --- |
+| `determinate: boolean` | Whether the indicator is in the determinate or indeterminate state. |
+| `progress: number` | The current progress. Value should be between [0, 1]. |
+| `open() => void` | Puts the component in the open state. |
+| `close() => void` | Puts the component in the closed state. |
