+### CloudFormation: "Rate exceeded"
+
+Stacks are being deployed all at once by default.
+
+If some stacks contain too many resources for the deployment to succeed, deployment dependencies can be defined to reduce amount of requests sent to CloudFormation, e.g.:
+
+```js
+import * as mca from "mca-monitoring";
+
+const app = mca.createApp();
+
+const stack = mca.setupMonitoringStack(app, "monitoring");
+const logGroupMonitoringStacks = stack.addDefaultLogGroupMonitoring();
+
+logGroupMonitoringStacks.forEach(logGroupMonitoringStack => {
+  stack.addDefaultLambdaMonitoring().forEach(defaultStack => defaultStack.addDependency(logGroupMonitoringStack));
+})
+```
