+- To add native platforms like android & ios , just run:
+
+```bash

+``` js
+<script type="text/javascript" src="js/config.js"></script>
+```
+``` js
+/// Usabilla Configuration
+const appId = 'YOUR_APP_ID_HERE';
+const formId = 'YOUR_FORM_ID_HERE';
+let event = 'YOUR_EVENT_TAG_HERE';
+const customVariable = {'YOUR_KEY_HERE': 'YOUR_VALUE_HERE'};
+```
+
+### Functions
+
+- Initialize the SDK and set custom variables for targeting campaigns
+```
+initialize → String appId , Object customVariable
+```
+``` js
+    const customVariable = {'YOUR_KEY_HERE': 'YOUR_VALUE_HERE'};
+    Usabilla.initialize(function() {}, function (err) {}, appId, customVariable);
+```
+- Show the passive form and return a JSON Object containing the results - rating, pageIndex and sent flag
+```
+loadFeedbackForm → String formId
+```
+``` js
+    Usabilla.loadFeedbackForm(function() {}, function (err) {}, formId);
+```
+- Load the passive form with the current screen captured and return a JSON Object containing the results - rating, pageIndex and sent flag
+```
+loadFeedbackFormWithCurrentViewScreenshot → String formId
+```
+``` js
+    Usabilla.loadFeedbackFormWithCurrentViewScreenshot(function() {}, function (err) {}, formId);
+```
+- Load the campaign and return a map containing the results - rating, pageIndex and sent flag
+```
+sendEvent → String event
+```
+``` js
+    Usabilla.sendEvent(function() {}, function (err) {}, event);
+```
+- Reset campaign data, so they can be triggered again from a fresh count
+```
+resetCampaignData()
+```

+```
+``` js
+    Usabilla.dismiss(function() {}, function (err) {});
+```
+- Set data masking based on passed/default rules using a passed/default character for obfuscation
+```
+setDataMasking → Array masks, String character
+```
+``` js
+    const masks = 'YOUR_Masking_Regex';
+    const maskCharacter = 'YOUR_Masking_Character';
+    Usabilla.setDataMasking(function() {}, function (err) {}, masks, maskCharacter);
+```
+- Return the array of default masking rules
+```
+getDefaultDataMasks()
+```
+``` js
+    Usabilla.getDefaultDataMasks(function() {}, function (err) {});
+```
+- Store form(s) in memory to be used in offline mode
+```
