what do you mean? Is really simple, just go to https://trackmyaudience.xyz, in the home page there is a How it Works? section with just 3 steps that shows with gifs how it works. Let me know if I can help you with something else
One of the biggest problem with these repl for complied languages is that they panic as soon as you rerun a command. `cling` integrates with Jupyter notebook too but as soon as you rerun a declaration of a variable, everything collapse and you have to reset the kernel.
