+## Luci builder file
+`try_builders.json` contains the supported luci try builders 
+for packages. It follows format:
+```json
+{
+    "builders":[
+        {
+            "name":"yyy",
+            "repo":"packages",

+        }
+    ]
+}
+```
+This file will be mainly used in [`flutter/cocoon`](https://github.com/flutter/cocoon) 
+to trigger/update pre-submit luci tasks.
