1. Explanation

You will download and run the script (application) that will:

2. Download the application

Open the terminal (Ctrl+T, or use the menu).
Copy-and-paste the following command to download the application. Warning: This looks like two lines because of the documentation formatting, but it's in fact just one line. Copy the entire thing and paste it into your terminal.
```
sudo wget --no-verbose --output-document=/usr/local/sbin/encryptinstallation https://www.dropbox.com/s/dmqnzqs1bbp6dm9/encryptinstallation?dl=1
```
Copy-and-paste the following command to enable the application to run.
```
sudo chmod +x /usr/local/sbin/encryptinstallation
```
If you are trying to install Ubuntu 18.04, skip this step. But, if you are trying to install Ubuntu 20.04, copy-and-paste the following command.
```
sudo sed --in-place -e 's/luksFormat/luksFormat --type=luks1/' /usr/local/sbin/encryptinstallation
```

In a moment, you will start the application. When you do so:

It will ask you some questions.
It will prepare your system for the Installer.
It will start the Installer.
When it starts the Installer, you will need to open the instructions (I'll remind you).

So…

Still in the terminal, enter this command:

encryptinstallation

Answer the questions, and when the Installer starts, open the instructions.
