+<string>Read and understand health data.</string>
+<key>NSHealthUpdateUsageDescription</key>

docs/Permissions.md

+These permissions are exported as constants of the `rn-apple-healthkit` module.

+Check the authorization status for sharing (writing) the specified data type.

+There is no way to check authorization status for read permission, [see this](https://developer.apple.com/documentation/healthkit/hkhealthstore/1614154-authorizationstatusfortype?language=objc).

docs/initHealthKit().md

+Initialize Healthkit. This will show the Healthkit permissions prompt for any read/write permissions set in the required `options` object.
+
+Due to Apple's privacy model if an app user has previously denied a specific permission then they can not be prompted again for that same permission. The app user would have to go into the Apple Health app and grant the permission to your react-native app under *sources* tab.
+
+For any data that is read from Healthkit the status/error is the same for both. This privacy restriction results in having no knowledge of whether the permission was denied (make sure it's added to the permissions options object), or the data for the specific request was nil (ex. no steps recorded today).
+
+For any data written to Healthkit an authorization error can be caught. If an authorization error occurs you can prompt the user to set the specific permission or add the permission to the options object if not present.
+
+If new read/write permissions are added to the options object then the app user will see the Healthkit permissions prompt with the new permissions to allow.
+
+`initHealthKit` requires an options object with Healthkit permission settings
+```javascript
+let options = {
+    permissions: {
+        read: ["Height", "Weight", "StepCount", "DateOfBirth", "BodyMassIndex"],
+        write: ["Weight", "StepCount", "BodyMassIndex"]
+    }
+};
+```
+
+```javascript
+AppleHealthKit.initHealthKit(options: Object, (err: string, results: Object) => {
+    if (err) {
+        console.log("error initializing Healthkit: ", err);
+        return;
+    }
+    // Healthkit is initialized...
+    // now safe to read and write Healthkit data...

docs/initStepCountObserver().md

+Setup an HKObserverQuery for step count (HKQuantityTypeIdentifierStepCount) that will
+trigger an event listenable on react-native `NativeAppEventEmitter` when the
+Healthkit step count has changed.
+
+The `initStepCountObserver` method must be called before adding a listener to
+NativeAppEventEmitter. After the step count observer has been initialized you can
+listen to the NativeAppEventEmitter `change:steps` event and re-fetch relevent
+step count data in the event handler.
+
+The `initStepCountObserver` method should be called after Healthkit has been
+successfully initialized (AppleHealthKit.initHealthKit has been called without
+error).
+
+```javascript
+// import NativeAppEventEmitter from react-native
+import {
+  Navigator,
+  View,
+  NativeAppEventEmitter,
+} from 'react-native';
+```
+
+```javascript
+AppleHealthKit.initHealthKit(HKOPTIONS, (err, res) => {
+  if (this._handleHKError(err, 'initHealthKit')) {
+    return;
+  }
+
+  // initialize the step count observer
+  AppleHealthKit.initStepCountObserver({}, () => {});
+
+  // add event listener for 'change:steps' and handle the
+  // event in the event handler function.
+  //
+  // when adding a listener, a 'subscription' object is
+  // returned that must be used to remove the listener
+  // when the component unmounts. The subscription object
+  // must be accessible to any function/method/instance
+  // that will be unsubscribing from the event.
+  this.sub = NativeAppEventEmitter.addListener(
+    'change:steps',
+    (evt) => {
+      // a 'change:steps' event has been received. step
+      // count data should be re-fetched from Healthkit.
+      this._fetchStepCountData();
+    }
+  );
+
+  // other tasks to perform after Healthkit has been
+  // initialized (fetch relevant Healthkit data).
+  this._fetchStepCountData();
+  this._fetchOtherRelevantHealthkitData();
+  // ...
+});
+
+...
+
+// when the component where the listener was added unmounts
+// (or whenever the listener should be removed), call the
+// 'remove' method of the subscription object.
+componentWillUnmount() {
+  this.sub.remove();
+}
+```

docs/isAvailable().md

+Check for Healthkit availability
+
+```javascript

+  if (err) {
+    console.log("error initializing Healthkit: ", err);

+Save a step count sample.
+
+A step count sample represents the number of steps during a specific period of time. A sample should be a precise as possible, with startDate and endDate representing the range of time the steps were taken in.

+```javascript
+// startDate and endDate are 30 minutes apart.
+// this means the step count value occurred within those 30 minutes.
+let options = {
+  value: 100,
+  startDate: (new Date(2016,6,2,6,0,0)).toISOString(),
+  endDate: (new Date(2016,6,2,6,30,0)).toISOString()

+```javascript

docs/setObserver().md

+Will listen for any updates in a given type data in healthKit and call app.
+
+type - one of the `['Walking', 'StairClimbing', 'Running', 'Cycling', 'Workout']`
+```javascript 1.8
+import { NativeAppEventEmitter } from 'react-native';
+//...//
+AppleHealthKit.setObserver({ type: 'Walking' });
+NativeAppEventEmitter.addListener(
+      'observer',
+      callback
+    );
+```
+
+So, callback would be call when new data of given type appears. When it happens, in order to get new info
+need to call getSamples() function with proper arguments.
