So, Ivy has been replaced with Ark documentation. Ark requires python >=3.10 (at the time of writing this), and heim doesn't have that (yet). So I had to install pyenv and then

pyenv install 3.11.2

and in the directory of this project I did

pyenv local 3.11.2

to install ark, I used

pip install --user ark

of course ark didn't work out of box. I had to remove the old 'ext' directory, then I had to remove the 'lib' directory, generate a new one from and ark test install (I used ark init to generate the necessary files) and copy it over. Looks like it is working now.

All I have to do is a ark biuildin the site directory.
