+  /**
+   * The constraints parameter is a MediaStreamConstraints object specifying the types of media to request, along with any requirements for each type.
+   */
+  constraints?: MaybeRef<MediaStreamConstraints>

+}
+```
+
+### `constraints`
+
+Type: `constraints?: MaybeRef<MediaStreamConstraints>`
+
+The `constraints` object is passed to the `navigator.mediaDevices.getUserMedia` method. It is used to specify the media
+types and settings for the stream.
+
+::: warning
+By default, the constraints object is `{audio: false, video: false}`. You should set at least one of the properties to
+`true` to get a stream/data.
+:::
+
+### `mediaRecorderOptions`
+
+Type: `mediaRecorderOptions?: MaybeRef<MediaRecorderOptions>`
+
+[See MDN](https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder/MediaRecorder#options)
+
+```ts
+interface MediaRecorderOptions {
+  audioBitsPerSecond?: number;
+  bitsPerSecond?: number;
+  mimeType?: string;
+  videoBitsPerSecond?: number;
+}
+```
+
+## `useMediaRecorder` values
+
+### `data`
+
+- Type: `Ref<Blob[]>`
+- Initial value: `ref([])`
+
+An array of Blobs that are created by the MediaRecorder. The Blobs are created when the MediaRecorder is stopped. Or
+when the timeslice is set and the timeslice is reached.
+
+### `stream`
+
+- Type: `ShallowRef<MediaStream | undefined>`
+- Initial value: `shallowRef()`
+
+### `state`
+
+- Type: `ShallowRef<MediaRecorderState | undefined>`
+- Initial value: `shallowRef()`
+
+The current state of the MediaRecorder. The state can be one of the following:
+
+- `undefined` - The MediaRecorder is not initialized.
+- `'inactive'` - The MediaRecorder is not recording.
+- `'recording'` - The MediaRecorder is recording data.
+- `'paused'` - The MediaRecorder is paused.
+
+### `mimeType`
+
+- Type: `ComputedRef<string | undefined>`
+- Initial value: `computed(()=>{})`
+
+The mimeType of the MediaRecorder. The mimeType is set when the MediaRecorder is initialized and the stream is
+available. You can also set the mimeType manually via [`mediaRecorderOptions.mimeType`](#mediarecorderoptions).
+
+::: warning
+If you set the mimeType manually (not recommended), make sure that the mimeType is supported by the browser. You can
+check if the mimeType
+is supported via [`isMimeTypeSupported`](#ismimetypesupported).
+:::
+
+### `isMimeTypeSupported`
+
+- Type: `ComputedRef<boolean>`
+
+If you set the mimeType manually, you can check if the mimeType is supported by the browser via this computed ref.
+
+### `isSupported`
+
+- Type: `ComputedRef<boolean>`
+
+If the MediaRecorder API (and the selected MIME type) is supported by the browser.
+
+### `mediaRecorder`
+
+- Type: `ComputedRef<MediaRecorder | undefined>`
+- Initial value: `computed(()=>{})`
+
+The MediaRecorder instance. The MediaRecorder is created when the stream is available.
+
+## `useMediaRecorder` methods
+
+### `start(timeslice: number | undefined): Promise<void>`
+
+- MDN: [MediaRecorder.start()](https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder/start)
+
+Creates the stream and the MediaRecorder instance. The stream is created with the constraints object. The MediaRecorder
+is created with the stream and the mediaRecorderOptions object.
+
+### `pause(): void`
+
+- MDN: [MediaRecorder.pause()](https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder/pause)
+
+### `resume(): void`
+
+- MDN: [MediaRecorder.resume()](https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder/resume)
+
+### `stop(): void`
+
+- MDN: [MediaRecorder.stop()](https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder/stop)
