+## GitHub Action - Cloudsmith Quota Alert
+
+This workflow checks Cloudsmith quota usage via the API.
+
+It sends separate alerts for:
+
+- Storage usage
+- Bandwidth (downloaded) usage
+
+---
+
+### Setup
+
+1. Add your Cloudsmith API key as a secret:  
+   `CLOUDSMITH_API_KEY`
+
+2. Add your Slack webhook URL as a secret:  
+   `SLACK_WEBHOOK_URL`
+
+3. In the workflow file, replace `your-org-name` with your Cloudsmith org name.
+
+---
+
+### How it works
+
+- Runs hourly or on manual trigger
+- Calls the quota history API
+- Parses the latest storage and bandwidth usage
+- Compares against 50%, 75%, and 90% thresholds
+- Sends Slack alerts using display values (e.g. "62.6 GB of 1000 GB")
+
+---
+
+### Example Alert
+
+> ⚠️ Cloudsmith **storage** usage is at 75% (750 GB of 1000 GB)
+
+> ⚠️ Cloudsmith **bandwidth** usage is at 90% (17.6 TB of 19.5 TB)
