# Basics

The “Basics” tab lets you enter all the minimum information required to declare a server.

Fill out the fields:

* **Name:** this is your server hostname and the name it has in the YaK application
  * :warning: *Server names can only contains letters, numbers and "-" characters and cannot exceed 15 characters.*
* Select the **infrastructure** to deploy your servers to (Infrastructure must already exist)
* Select an **image** to install in the list of the "provider image name" field (see also note below)
* Select a server **shape**\
  (YaK comes with a list of default shapes, but more shapes can be added - see [dedicated section](/yak-user-doc/configuration/shapes.md))
* **Server Tags** (optional)
  * Server tags are key:value pairs that can be added to your server for your own purpose. You may add custom tags as per your need (this step is optional)
* **Network**
  * **IP address**: fill in as per your need or use automatic IP with public address. Assign IP addresses according to your cloud strategy and internal rules.
  * **Scope**: private or public IP address
  * **Mode:**
    1. Automatic (lets your provider assign a DHCP address to your server)
    2. Manual (this is to set an IP address manually)
    3. None (no IP address will be configured)
  * **Admin access checkbox:** Grant admin access to the YaK via this IP address.
    * At least one network interface must be set as "admin access", this is required for the Yak to connect to your server and deploy components on it.
  * Note: additional network interfaces can be added by clicking the "+" sign.

{% hint style="warning" %}
**Note:** Please note that images are specific to a region at some cloud providers (ex: AWS and OCI). This is not related to the YaK, but is a cloud provider's limitation.

An image declared with region "eu-central-1" for example, will be available to infrastructures that belong to the same region only.

If the same image needs to be used on 2 different regions, it must be declared twice (once for each region)

See "[Provider images](/yak-user-doc/configuration/images.md)" section for more details.
