Has anyone used the dillinger markdown editor?

I discovered this markdown editor tonight

It is Javascript. Not in my Debian repo, but has a Github site

from which you can download.
Its only requirement is Node.js V10.

It would be nice to know if someone has used it?
Or, is anyone willing to try?

I’m using the online version, when needed. It does a fairly good job, as far as I can tell.

I would want to install it locally, but at least you can say it functions.
Am currently using keenwrite.

I’d appreciate it if it ran on my own server.

It says this

Dillinger requires Node.js v10+ to run.

Install the dependencies and devDependencies and start the server.

cd dillinger
npm i
node app

That to me seems to imply that it can be installed locally?
Vague instructions… bad vibes maybe

I didn’t try, but I assume it will work as promised.
