Find an editor

StackEdit is nice for not saving and for editing and previewing in the browser anytime.
But it can't handle code files so maybe those go to another repo or they come markdown or Jupiter notebooks (but they don't really change so that's overkill)
Could even link to another site to run snippets in the browser which is nice trying out code. Though it gets away from the feeling of installing and running locally - that could always be limited to quickstart in markdown so not every script needs to run.
PHP is different as a server and website but it is not so useful and readable anyway so maybe needs a new approach. Also those won't be edited online without running locally anyway.
Also there are templates for pages to enforce structure.

Forestry would mean editing online easily both YAML and content. Check on YAML gui.
Can scripts be edited?

Jekyll Admin is nice for a YAML-based approach. But it's a hassle for only working locally and needing commits.

To avoid a mono repo, code might have to move out or become markdown and that make the editor choice easier.
The install and run instructions could always point to the code repo.
