Install Trial in Lazarus

I currently use VCL UI Pack with Delphi Rio, but would like to switch to FNC because of the Lazasus support, while still developing with Delphi.
I downloaded the trial Delphi 10.3 version but see no download for Lazarus and cannot find any installation instructions.
Any step by step for Lazasus? Especially for ssomeone new to it. 

Lazarus Support is included in the installer for Delphi, the registered version. There is no trial support for Lazarus.
