+# Tournament data
+
+This directory contains JSON files for tournament trees.
+
+This is a temporary solution until the automatic tournament tree generation is completed.
+
+# Structure
+
+## Naming
+
+Tournament name with `_` as separators and `.json` suffix.
+
+## JSON structure
+
+```json
+{
+  "rounds": [
+    [
+      {
+        "opponent_1_id": 1,
+        "opponent_2_id": 2,
+        "winner": 1
+      },
+      {
+        "opponent_1_id": 3,
+        "opponent_2_id": 4,
+        "winner": null
+      }
+    ],
+    [
+      {
+        "opponent_1_id": 1,
+        "opponent_2_id": null,
+        "winner": null
+      }
