-## Running
+## Deploy
+
+In order to deploy the you endpoint simply run
+
+```bash
+serverless deploy
+```
+
+The expected result should be similar to:
+
+```bash
+Serverless: Packaging service...
+Serverless: Uploading CloudFormation file to S3...
+Serverless: Uploading service .zip file to S3 (1.47 KB)...
+Serverless: Updating Stack...
+Serverless: Checking Stack update progress...
+..............
+Serverless: Stack update finished...
+
+Service Information
+service: scheduled-cron-example
+stage: dev
+region: us-east-1
+api keys:
+  None
+endpoints:
+  None
+functions:
+  scheduled-cron-example-dev-cron: arn:aws:lambda:us-east-1:377024778620:function:scheduled-cron-example-dev-cron
+  scheduled-cron-example-dev-secondCron: arn:aws:lambda:us-east-1:377024778620:function:scheduled-cron-example-dev-secondCron
+```
+
+There is no additional step required. Your defined schedule becomes active right away after deployment.
+
+## Usage
 
 To see your cron job running tail your logs with:
 
 ```bash
 serverless logs --function cron --tail
 ```
 
+The expected result should be similar to:
+
+```bash

+
+Since this only shows you the logs of the first cron job simply change the function name and run the command again:
+
+```bash
+serverless logs --function secondCron --tail
