 # VulnAlerts - Customized CVE Alerts straight to your Slack Channel
 
 ## How to Use?
-- Fork the project.
 - [Create an Incoming Webhook on Slack](https://slack.com/intl/en-in/help/articles/115005265063-Incoming-WebHooks-for-Slack)
 - Goto Repository Settings -> Secrets -> Add a New Secret
 - Enter ```SLACK_WEBHOOK``` in the Secret Name and your slack webhook in the value.
 - Add CPEs of the products that you want to monitor for vulnerabilities in the **cpe.txt** file. [NVD CPE Search](https://nvd.nist.gov/products/cpe/search)
+- Create new workflow in .github/workflows/alerts.yml
+```
+name: VulnAlerts
+
+on: 
+  schedule:
+    - cron:  '15 * */1 * *'
+
+jobs:
+  alert:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@master
+    - uses: y-mehta/vulnalerts@master
+      env:
+        SLACK_WEBHOOK: ${{ secrets.SLACK_WEBHOOK }}
+    - name: done
+      run: echo 'done'
+```
+
 - That's it. You'll receive daily alerts on the selected slack channel.
 
 Note: No need to enter full CPE unless you want to monitor specific version. ```apple:icloud``` or ```atlassian:sourcetree``` will do the job.
 
-- Action Schedule can be changed in ```.github/workflows/alert.yml``` if needed. Follow crontab format(@daily,@monthly etc. aren't supported by Github Actions)

 ## How it Works?
 - GitHub Actions WorkFlow is automatically triggered based on schedule.
 - [CVE-Recent JSON Vulnerability Feed](https://nvd.nist.gov/feeds/json/cve/1.1/nvdcve-1.1-recent.json.gz) is fetched from the NVD.
 - The JSON feed is processed to check if any CPEs mentioned in **cpe.txt** are present in the Feed.
 - After processing is done, It'll send the message to Slack Incoming Webhook.

 ## Security Warning
 - Don't hardcode your Slack Incoming Webhook URL into the python file.
