I want to build a similar playground for people who want to get familiar with the tools my Shell Bling Ubuntu repo provides ( https://github.com/hiAndrewQuinn/shell-bling-ubuntu ). Ideally it consists of a series of very simple tasks to get one's feet wet with each tool provided: Using fish's autocompletion, then using fzf's shell keybindings, then using rg instead of grep to search an enormous number of files for a single needle character in a million lines of wheat , and so on.

I have no clue how to do this safely. I've never seen how anyone else does it either. Can anyone provide me some pointers?
