 1. Add `crud` to dependencies in the project rockspec.
 
-**Note**: it's better to use tagged version than `scm-1`.
-Check the latest available [release](https://github.com/tarantool/crud/releases) tag and use it.

-dependencies = {
-    ...

+
+3.  Start the application and create `customers-storage` and
+    `customers-router` replica sets.
+
+4.  Don't forget to bootstrap vshard.
+
+5.  Configure the statistics with clusterwide configuration
+    (see `crud.cfg` options in [statistics](#statistics) section):
+    ```yaml
+    crud:
+      stats: true
+      stats_driver: metrics
+      stats_quantiles: false
+      stats_quantile_tolerated_error: 0.001
+      stats_quantile_age_buckets_count: 5
+      stats_quantile_max_age_time: 180
+    ```
 
 Now your cluster contains storages that are configured to be used for
 CRUD-operations.
