+# Staying up to date with Dependabot
+
+It is recommended to group the Testcontainers update modules for dependabot using the following configuration:
+
+```yaml
+version: 2
+updates:
+  - package-ecosystem: "gomod"
+    directories:
+      - "/"
+      - ...
+    schedule:
+      interval: "daily"
+    groups:
+      testcontainers-go:
+        patterns:
+          - "github.com/testcontainers/testcontainers-go"
+          - "github.com/testcontainers/testcontainers-go/modules/*"
+```
+
+This ensures that all modules are updated at the same time, and that the PRs are grouped together. 
+
+It also helps to avoid conflicts and makes it easier to review the changes.
