 On each microservice in example/microserivces, perform the following steps
   - *Do this for microservices: books, orders, & reverse proxy
-  - Install dotenv `npm install dotenv`
-  - Create a .env file across each ,microservices and input your own Mongodb Atlast URI for both Microservice_URI and CHRONOS_URI
-    - ** Reverse Proxy .env file will only require CHRONOS_URI
+  - Create a .env file under each microservice folder and input your own Mongodb Atlast URI for Microservice_URI, CHRONOS_URI and ORDER_URI, see example below:
 
 ```
 BOOK_URI = mongodb+srv://<username>:<password>@cluster0.o2hx5.mongodb.net/<dbname>?retryWrites=true&w=majority
 
 CHRONOS_URI = mongodb+srv://<username>:<password>@cluster0.o2hx5.mongodb.net/<dbname>?retryWrites=true&w=majority
-```
-  - In each Microservice Mode.js file import and set the Microservice_URI
-
-```
-const myURI = process.env.BOOK_URI;
 
+ORDER_URI = mongodb+srv://<username>:<password>@cluster0.o2hx5.mongodb.net/<dbname>?retryWrites=true&w=majority
 ```
+  - In each Microservice Mode.js file import and set the Microservice_URI
+  - In each Microservices *chronos-config.js* file, verify that `"mode"` property has a value of `"microservices"`
 
-  - In each of the chronos-config.js files, import and set URI property in database to the Chronos_URI as shown
-
-```
-require('dotenv').config();
-const chronos = require('@chronosmicro/tracker');
-
-chronos.use({
-  microservice: 'name of microservice e.g books or orders',
-  interval: 2000,
-  database: {
-      type: 'MongoDB'
-      URI: process.env.CHRONOS_URI
-    },
-  notifications: [],
-})
 ```
   - **Note: The Initialize Chronos step is already taken care of for you. 
+  - Inside each microservice directory, install all dependencies using the `npm install`
   - Run `npm run start` in each folder directory
-    - To do so, within each microservice directory, install all dependencies using the `npm install`
   - Head over to localhost:3030 to view reverse proxy acting as the frontend of this microservice example
   - Start adding data!
   - Run `npm run both` to start Electron app
