The current HowDoI wiki states
Please do not add any new "How Do I" pages. Instead write a tutorial for the developer.gnome.org website i.
I see problems with the new site:
HowDoI gave a clear spectrum of what it should contain.
The new page does not. It simply says “tutorial”.
Some tutorials will be for ultimate beginners, some for advanced users. Rating and improvement of tutorials will become difficult.
Create a site stating what granularity you expect the tutorials to be.
HowDoIs were easy to create: Open non-existing site, click “create”, write your stuff; Edit on occasions.
The new page requires you to install software locally and to build your tutorial. Further, it does not give
Not many people will be eager to write a tutorial here. It’s much easier then to write it in a blog, in one’s own wiki or in some document (google docs / offline). The outcome is, that (again) tutorials and information will be spread on the internet and hard to find. This might lead to a value loss of GTK, as dev cost is going up with missing information.
Make the system easier to approach. Even if the backend is what it is, build a wiki-style interface around it, which makes things easy to correct.
Judging from the root page of the new site, tutorials apparently ought to be read and searched for on Gitlab.
The content won’t be searchable by search engines rendering them very unuseful for newcomers who don’t already know where to look for.
Create usual html pages on gnome.org containing the content. And always put a link to the source inside the document, so users who want to edit can edit.
