+# Dashboard Fusion
+
+Dashboard Fusion is a tool for merging and updating Grafana dashboards by combining panels from different sources. 
+It's designed to be used when working with dashboards that share common panels.
+It allows to update existing panels, while preserving the dashboard layout.
+
+## Fusion Behavior
+
+Fusion is performed by merging panels from multiple sources into a single dashboard.
+- Panels are matched by title and type.
+- If a panel with the same title and type exists in the dashboard, its content will be replaced, except for its position (preserving the dashboard layout).
+- If a panel with the same title and type does not exist in the dashboard, it will be appended to the end of the dashboard.
+Later, the dashboard can be manually reorganized to achieve the desired layout.
+
+## Usage
+
+```bash
+# Merge panels from panels1.json and panels2.json into dashboard.json and save the result to output.json
+go run ./cmd/dashboard-fusion --dash <dashboard.json> --panels <panels1.json,panels2.json> --out <output.json>
+```
