Hi @orhtej2 ! thanks for your suggestion and PR.
We believe it's a good idea to add this to the unofficial installation methods; first we're gonna reach yunohost to see if they can use a specific referer.

Meanwhile, we leave this PR waiting.

Nonetheless, a documentation change like this could point directly to staging, if you'd like to. see you soon!

Suggested change

	* Penpot is available <a href="https://apps.yunohost.org/app/penpot">in the catalog</a> of apps installable on YunoHost instances.
	* Penpot is available <a href="https://apps.yunohost.org/app/penpot">in the catalog</a> of apps installable on <a href="https://yunohost.org/">YunoHost</a> instances.

I think it would be nice to include a link to the YunoHost landing page to explain what it is to people that don't already know

I was considering that initially but decided against it to avoid link spam, especially given catalog page links to both landing and instructions on how to via 'Install with YNH' button.

But I'm OK with linking YNH landing as long as Penpot maintainers don't consider it excessive 👍

I must admit I was confused with CONTRIBUTING.md and went for the safe option :)
If you're willing to push it straight to staging I'm all for it 👍
