Creating your first Catala program
Now that you have installed the Catala tooling, you can test its correct
execution with the equivalent of a Hello, world! program.
Catala programs are just text files that can be handled by any text editor/IDE. Hence, to kickstart your Catala development, we recommend you open your favorite text editor.
The Catala maintenance team currently only provides full support for the VSCode text editor (syntax highlighting, language server, formatter).
