You should start with installing Racket
on your computer.
For example, on Debian
you should issue this command as root:
This command will install Racket environment on your computer.
Next you should install bystroTeX using this command as normal user
(i.e. not root):
racket -e '(require (planet "amkhlv/bystroTeX/slides_setup.rkt"))'
This command will talk back to you, asking some questions and giving further instructions.
In particular, it will ask you to choose a folder where a sample slide presentation is stored.
After the installation, go to that sample folder.
