+# Location Manager
+
+The 💠[component](../scopes.md) responsible for location tracking functionality for Telegram Mini
+Apps.
+
+## Checking Support
+
+To check if location tracking is supported by the current Telegram Mini Apps version, use the
+`isSupported` signal:
+
+::: code-group
+
+```ts [Variable]
+import { locationManager } from '@telegram-apps/sdk';
+
+locationManager.isSupported(); // boolean
+```
+
+```ts [Functions]
+import { isLocationManagerSupported } from '@telegram-apps/sdk';
+
+isLocationManagerSupported(); // boolean
+```
+
+:::
+
+## Mounting
+
+Before using the component, it must be mounted.
+
+This process is asynchronous, as location manager settings need to be requested from the Telegram
+application. The `isMounting` signal will be set to `true` during the process and updated to `false`
+when complete.
+
+If mounting is successful, the `isMounted` signal will be set to `true`. If errors occur,
+the `mountError` signal will reflect the error.
+
+::: code-group
+
+```ts [Variable]
+if (locationManager.mount.isAvailable()) {
+  try {
+    const promise = locationManager.mount();
+    locationManager.isMounting(); // true
+    await promise;
+    locationManager.isMounting(); // false
+    locationManager.isMounted(); // true
+  } catch (err) {
+    locationManager.mountError(); // equals "err"
+    locationManager.isMounting(); // false
+    locationManager.isMounted(); // false
+  }
+}
+```
+
+```ts [Functions]
+import {
+  mountLocationManager,
+  isLocationManagerMounting,
+  isLocationManagerMounted,
+  locationManagerMountError,
+} from '@telegram-apps/sdk';
+
+if (mountLocationManager.isAvailable()) {
+  try {
+    const promise = mountLocationManager();
+    isLocationManagerMounting(); // true
+    await promise;
+    isLocationManagerMounting(); // false
+    isLocationManagerMounted(); // true
+  } catch (err) {
+    locationManagerMountError(); // equals "err"
+    isLocationManagerMounting(); // false
+    isLocationManagerMounted(); // false
+  }
+}
+```
+
+:::
+
+To unmount, use the `unmount` method:
+
+::: code-group
+
+```ts [Variable]
+locationManager.unmount();
+locationManager.isMounted(); // false
+```
+
+```ts [Functions]
+import { unmountLocationManager, isLocationManagerMounted } from '@telegram-apps/sdk';
+
+unmountLocationManager();
+isLocationManagerMounted(); // false
+```
+
+:::
+
+## Requesting Location
+
+To request the current location, use the `requestLocation` method. It returns a cancelable promise
+with an object, describing the current device location.
+
+The object contains the following numeric properties:
+
+| Property            | Description                                                          |
+|---------------------|----------------------------------------------------------------------|
+| latitude            | Latitude in degrees.                                                 |
+| longitude           | Longitude in degrees.                                                |
+| altitude            | _Optional_. Altitude above sea level in meters.                      |
+| course              | _Optional_. The direction the device is moving in degrees.           |
+| speed               | _Optional_. The speed of the device in m/s.                          |
+| horizontal_accuracy | _Optional_. Accuracy of the latitude and longitude values in meters. |
+| vertical_accuracy   | _Optional_. Accuracy of the altitude value in meters.                |
+| course_accuracy     | _Optional_. Accuracy of the course value in degrees.                 |
+| speed_accuracy      | _Optional_. Accuracy of the speed value in m/s.                      |
+
+::: code-group
+
+```ts [Variable]
+if (locationManager.requestLocation.isAvailable()) {
+  const location = await locationManager.requestLocation();

+
+if (requestLocation.isAvailable()) {
+  const location = await requestLocation();
+}
+```
+
+:::
+
+## Opening Settings
+
+To open the location manager-related settings modal, use the `openSettings` method. This method can
+only be triggered in response to user interaction.
+
+::: code-group
+
+```ts [Variable]
+if (locationManager.openSettings.isAvailable()) {
+  locationManager.openSettings();
+}
+```
+
+```ts [Functions]

+  openLocationManagerSettings();
