How to target Linux Platform on Delphi?

I want to develop an app for Linux using Delphi, but Linux isn't a target platform option on my side:

What are the steps to start developing and compiling apps for Linux using Delphi?

What do I need?

Here's a full guide for developing apps for Linux using Delphi:

Setting up WSL2 (Linux Environment):

1. Download Ubuntu from the Microsoft Store:
   
2. Once Ubuntu is installed, you can click on the Open button and set up your account:
   
3. Make sure your Ubuntu WSL is fully up to date using the following command:
   

sudo apt-get update -y && sudo apt-get upgrade -y

4. Setup Delphi PAServer using the following command
   

curl -L https://embt.co/SetupUbuntu4Delphi22 | bash

5. You can then launch/run Delphi PAServer with the following command:
   

~/pa22.sh

Setting up the Delphi IDE:

1. You need Delphi 10.4 or newer installed. This also needs to be the Enterprise Edition of the IDE.
2. Additionally, you need to make sure you have the Linux Platform installed in your IDE:
   
3. You need to install FMXLinux from the GetIt Package Manager:
   
4. Go to Tools > Options > Deployment > Connection Profile Manager and set up a connection to your PAServer in the Ubuntu WSL:
   
   
5. Go to Tools > Options > Deployment > SDK Manager and add a new Linux SDK:
   
   
6. Now you can then create a new Multi-Device Application (FireMonkey/FMX) and you should see Linux as an option:
   
   
7. If you don't see Linux, then you simply need to add it by right-clicking and selecting "Add Platform":
   
   

And that's it. Now you should be able to compile and build applications for Linux using Delphi.
