 The above example has two sources specified. Argo CD will generate the manifests for each source separately and combine 
 the resulting manifests.
 
+!!! warning "Do not abuse multiple sources"
+    Note that the example above is just for illustration purposes. This feature is **NOT** destined as a generic way to group your applications. Take a look at [applicationsets](../user-guide/application-set.md) and the [app-of-apps](../../operator-manual/cluster-bootstrapping/) pattern if you want to have a single entity for multiple applications. If you find yourself using more than 2-3 items in the `sources` array then you are almost certainly abusing this feature and you need to rethink your application grouping strategy.

 If multiple sources produce the same resource (same `group`, `kind`, `name`, and `namespace`), the last source to 
 produce the resource will take precedence. Argo CD will produce a `RepeatedResourceWarning` in this case, but it will 
 sync the resources. This provides a convenient way to override a resource from a chart with a resource from a Git repo.
