+# Progress Component
+
+`standalone`, `component`
+
+The Progress component is a simple component that can be used to display progress bars.
+
+## Usage
+
+```html
+<adf-progress [value]="50"></adf-progress>
+```
+
+### Variant
+
+The progress bar supports the following variants:
+
+- bar (default)
+- spinner
+
+```html
+<adf-progress variant="bar" [value]="50"></adf-progress>
+<adf-progress variant="spinner" [value]="50"></adf-progress>
+```
+
+### Mode
+
+The progress bar supports the following modes:
+
+- For progress spinner, the mode can be either `indeterminate` or `determinate`.
+- For progress bar, the mode can be either `determinate`, `indeterminate`, `buffer`, or `query`.
+
+> For the spinner variant, setting the mode to unsupported values will default to `indeterminate`.
+
+Example:
+
+```html
+<adf-progress [value]="50" mode="determinate"></adf-progress>
+<adf-progress [value]="50" mode="indeterminate"></adf-progress>
+```
+
+### Color
+
+The progress bar supports the following colors:
+
+- default
+- primary
+- accent
+- warn
+
+```html
+<adf-progress [value]="50" color="primary"></adf-progress>
+<adf-progress [value]="50" color="accent"></adf-progress>
+<adf-progress [value]="50" color="warn"></adf-progress>
+```
+
+## API
+
+Import the following standalone components:
+
+```typescript
+import { ProgressComponent } from '@alfresco/adf-core';
+```
+
+## Properties
+
+| Name      | Type            | Default         | Description                                               |
+|-----------|-----------------|-----------------|-----------------------------------------------------------|
+| `variant` | ProgressVariant | `bar`           | The progress bar variant.                                 |
+| `value`   | number          |                 | The value of the progress bar.                            |
+| `color`   | ProgressColor   |                 | The color of the progress bar.                            |
