 # Sharded cluster
 
-A sample application demonstrating how to configure a [sharded](https://www.tarantool.io/en/doc/latest/concepts/sharding/) cluster.
+A sample application created in the [Creating a sharded cluster](https://www.tarantool.io/en/doc/latest/how-to/vshard_quick/) tutorial.
 
 ## Running
 
-To run the cluster, go to the `sharding` directory in the terminal and perform the following steps:
-
-1. Install dependencies defined in the `*.rockspec` file:
-
-   ```console
-   $ tt build sharded_cluster
-   ```
-   
-2. Run the cluster:
-
-   ```console
-   $ tt start sharded_cluster
-   ```
-
-3. Connect to the router:
-
-   ```console
-   $ tt connect sharded_cluster:router-a-001
-   ```
-   
-4. Perform the initial cluster bootstrap:
-
-   ```console
-   sharded_cluster:router-a-001> require('vshard').router.bootstrap()
-   ---
-   - true
-   ...
-   ```
-
-5. Insert test data:
-
-   ```console
-   sharded_cluster:router-a-001> insert_data()
-   ---
-   ...
-   ```
-   
-6. Connect to storages in different replica sets to see how data is distributed across nodes:
-
-   a. `storage-a-001`:
-
-      ```console
-      sharded_cluster:storage-a-001> box.space.bands:select()
-      ---
-      - - [1, 614, 'Roxette', 1986]
-        - [2, 986, 'Scorpions', 1965]
-        - [5, 755, 'Pink Floyd', 1965]
-        - [7, 998, 'The Doors', 1965]
-        - [8, 762, 'Nirvana', 1987]
-      ...
-      ```
-   
-   b. `storage-b-001`:
-
-      ```console
-      sharded_cluster:storage-b-001> box.space.bands:select()
-      ---
-      - - [3, 11, 'Ace of Base', 1987]
-        - [4, 42, 'The Beatles', 1960]
-        - [6, 55, 'The Rolling Stones', 1962]
-        - [9, 299, 'Led Zeppelin', 1968]
-        - [10, 167, 'Queen', 1970]
-      ...
-      ```
