-# LiteCharms
+# LiteCharms.Scheduler
+
+The background processing engine responsible for automated tasks and scheduled jobs.
+
+## 🏗 Architecture
+* **Type:** Kubernetes **StatefulSet**
+* **Persistence:** Uses Postgres at `192.168.1.170`.
+* **Clustering:** Configured for Quartz.NET/Hangfire clustering to support multiple replicas without task duplication.
+
+## 🚀 CI/CD Workflow
+* **Trigger:** Pull Request to `master`.
+* **Versioning:** Automated Gitea Releases with links to Docker and NuGet artifacts.
+* **Identity:** Uses stable network identifiers (`litecharms-scheduler-0`, etc.) to maintain lock integrity in the database.
+
+## ⚙️ Scaling
+To scale the scheduler:
+`kubectl scale statefulset litecharms-scheduler --replicas=3`
+*Note: Ensure Database Job Store is enabled in appsettings before scaling.*
