writing documentation takes a lot of endurance

it also practically cries out for procrastination, via complaining about it in chat rooms

that said, I've made some decent headway on the Built-Ins page for the new http://perun.io

@podviaznikov I upgraded to the latest snapshot of Perun in my working copy of the new http://perun.io, but it's likely that it will conflict with your work, if you've done something similar. Let me know if I should commit my stuff, or wait for you and merge before I push.

I surprised myself and finished a first draft of Built-Ins. Proofreaders are welcome, and feel free to be picky, I'm not fragile. https://github.com/hashobject/perun.io/blob/built-ins/guides/built-ins.md

Great job @bhagany! I didn’t do anything until now. But I made minor changes and merged your updates and @martinklepsch original PR into http://perun.io. It’s live now https://perun.io/

great!

Feel free to merge directly any small content changes to http://perun.io for now

okay, will do
