# Installing PrestaShop 8 using the command-line script
## What is it?
{% hint style="info" %}
This special installer makes it possible to install PrestaShop without the need to use a web browser: simply put the content of the zip archive on your web server, and you can install PrestaShop through your command-line interface (CLI).
{% endhint %}
Any CLI software can be used, as long as you can use it to interact with the server's commands: Bash, Windows PowerShell, OS X Terminal, PuTTY, etc.
The point of having a CLI installer in addition to the regular in-browser installer is to give this option to cater to some advanced users, who often prefer command-line interfaces as they tend to provide a more concise and powerful means to control a program or operating system.
## How do I use it?
The CLI installer is easy to use: from your terminal, **go to the `/install` (or `/install-dev`) folder** (meaning you have previously unzipped the prestashop.zip file), and **start the script with this command:**
```
$ php index_cli.php
```
This will display the various available options.
All the options from the regular in-browser installer are available, with their default value listed. **Almost all default values can be left as is** because you can edit them all from the PrestaShop back office once the installation is done.
{% hint style="info" %}
The e-mail and password are the ones used to create the administrator's back office account.
{% endhint %}
To start the installation, **you need to 5 arguments:**
* **domain**. The location where you want your store to appear.
* **db\_server**. The database server address.
* **db\_name**. The name of the database you want to use.
* **db\_user**. The username for the database you want to use.
* **db\_password**. The password for the database username used above.
For instance:
```
$ php index_cli.php --domain=example.com --db_server=sql.example.com --db_name=prestashop --db_user=root --db_password=123456789
```
{% hint style="info" %}
If you also set the **`--email`** value to your own address, a recap e-mail will be sent to you once the installation is done.
{% endhint %}
