+# Examples for mongodbatlas_advanced_cluster (Preview for MongoDB Atlas Provider v2)
+
+This directory contains examples of using the `mongodbatlas_advanced_cluster` resource for the **Preview for MongoDB Atlas Provider v2**.
+
+In order to enable the Preview, you must set the enviroment variable `MONGODB_ATLAS_ADVANCED_CLUSTER_V2_SCHEMA=true`, otherwise the current version will be used.
+
+You can find more info in the [resource doc page](https://registry.terraform.io/providers/mongodb/mongodbatlas/latest/docs/resources/advanced_cluster%2520%2528preview%2520v2%2529).
