+
+Two branches are created one for js-sdk-common and one for js-client-sdk in a single repo. Download the code  
+
+1. Go to js-client-sdk directory and run 'npm link path-to-js-sdk-common-dir'
+
+2. Go to your project directory and run 'npm link path-to-js-client-sdk-dir'
+
+3. In your project directory run 'npm install'
+
+4. Import js-client-sdk in your project
+
+```javascript
+import * as LDClient from "js-client-sdk";
+```
+
+5. Create user object for which flags needs to be evaluated
+
+```javascript
+var user = {
+  "key": "abcd343",
+  "country": "US"
+};
+```
+
+6. Add flag keys in options to initialize client object with flags
+ 
+```javascript
+var options = {
+
+  flagKeys: ["js-flag"]
+
+}
+```
+
+7. Provide browser-client-id that starts with 'test-client' as first argument in initialize and user and options object
+
+```javascript
+var ldclient = LDClient.initialize('test-client-*************', user, options);
+```
+
+8. Wait for the client to get ready 
+
+```javascript
+ldclient.on('ready', function() {
+  
+  var jsFlag = ldclient.variation("js-flag", 'off');
+  
+  if (jsFlag == 'on') {
+    
+    console.log("Hello. Js Flag is on");
+    
+  } else {
+  
+    console.log("Hello. Js Flag is off");
+
+  }
+```
