+# net.box
+
+A sample application containing `net.box` requests from the [Getting started with net.box](https://www.tarantool.io/en/doc/latest/how-to/getting_started_net_box/) tutorial.
+
+
+## Running
+
+Before running this sample, start an application that allows remote connections to a sample database: [sample_db](../instances.enabled/sample_db).
+
+Then, start the interactive session by executing the following command in the [connectors](..) directory:
+
+```console
+$ tt run -i net_box/myapp.lua
+```
+
+In the console, you can use the `conn` object to execute requests for manipulating the data.
