# Changing the installation domain

{% hint style="warning" %}
**The domain that you entered during installation is the only domain that's "baked-in".**
{% endhint %}

{% hint style="info" %}
**Installation Domain**

The installation domain serves some vital functions in your ESP platform such as receiving webhooks, displaying images while editing email templates inside of the platform, encrypting your connection with HTTPS, and other administrative components. 
{% endhint %}

{% hint style="success" %}
You can change your installation domain at any time, just SSH into your server or use the Digital Ocean Droplet Console and run the following commands:
{% endhint %}

```
cd edcom-install
```

```
./update_domain.sh
```

```
./restart.sh
```

{% hint style="warning" %}
The installation domain must match the A record in your DNS provider ***exactly*** including subdomain. If your DNS record is esp.fivetacofiesta.com your installation domain must also be esp.fivetacofiesta.com.
{% endhint %}
