+# INSTALLATION GUIDE for Debian Mail-in-a-Box
+
+=============
+
+## Prerequisites
+
+In order to install Debian Mail-in-a-Box, you need a machine with these mininum specifications:
+
+- OS: Debian 12
+- RAM: at least 512MB
+- Disk: at least 6GB
+
+Once you met these specifications, you need to install sudo. We could use ```su``` but is more easy to use the package ```sudo```.
+
+```bash
+ su -
+ apt-get install sudo
+ adduser [yourusername] sudo
+ exit
+ reboot
+```
+
+Now your user account have the sudo access.
+After that, you need to install some utilities:
+
+```bash
+ sudo apt-get update
+ sudo apt-get upgrade
+ sudo apt-get install git
+```
+
+## Installing Debian Mail-in-a-Box
+
+Now you can proceed with the installation of the mail server:
+
+```bash
+ git clone https://github.com/AiutoPcAmico/debian-mailinabox.git
+ cd debian-mailinabox
+ sudo ./setup/start.sh
+```
+
+During the setup, you have to answer different questions.
+
+First, you need to specify the Locales framework.
+Please, select **en_US.UTF-8 UTF-8** and default locale for the system environment **en_US.UTF8**
+
+The script now installs all necessary packages. It might take some time (up to 15 minutes).
+At the end, you'll need to answer a few questions about configuring Debian Mail-in-a-Box.
+
+First of all you will be asked for an email address for configuring the mail server.
+Usually it is configured as ```me@[servername].[domain].[tld]``` but personally I prefer to change it to ```[anotherusername]@[domain].[tld]```. 
+This way Mail-in-a-Box will take care of the mail server for the main domain and the administrator user will be unknown.
+
+Then you can indicate the subdomain where the mail server will be hosted (which you will reach via the Web GUI).
+I recommend keeping the format ```box.[domain].[tld]```.
+
+At last, select if you want to keep enabled postgrey greylist.
+
+Once the setup script finished installing all the components (which can take a long time) you will be asked to create your first email account.
+I recommend you setting it identical to the administration account ```[anotherusername]@[domain].[tld]```, so as to have a separate email for any logs or problems.
+
+## Next Steps
+
+Now your Debian Mail-in-a-Box is working!
+You can reach your email admin page by following the url provided by the script.
+You can now follow the guides from the official website to complete the setup and creation of your first email account.
+
+Good luck!
