# Adding connection info in Yandex DataLens

To add connection details, do the following:

1. Open the connection to add details for.
1. Click ![image](../../../_assets/console-icons/circle-info.svg) at the top of the screen.
1. Enter the information and click **Save**.

   {% cut "Adding connection info" %}

   ![add-description](../../../_assets/datalens/connection/connection-add-description.png)

   {% endcut %}

1. Click **Save changes** at the bottom.

Now all users will see the ![image](../../../_assets/console-icons/circle-info.svg) icon in the top-right corner of the connection. Clicking it will open the **Connection info** window with the information.

{% cut "Viewing connection info" %}

![description](../../../_assets/datalens/connection/connection-description.png)

{% endcut %}

To remove connection info, save an empty field in the **Connection info** window. Users will no longer see the ![image](../../../_assets/console-icons/circle-info.svg) icon.
