Documentation improvement initiative

This is an unsorted list of tasks, which improve the documentation. The original thread on the forum can be found here.

The List

Id	Description	Info / Guides / People working on
1	promote wiki.dlang.org directly on D's webpage
1b	abandon the wiki, transfer the content to github
2	encourage authors to copy/write/(at least link) articles/tutorials/cookbooks on the wiki	many articles/tutorials/cookbooks exist on the wiki, but also many are scattered threw out the web
3	on code.dlang.org decrease score of packages, which don't build
4	Link tutorials or cookbooks in language and library reference	Existing examples are simple and clear. A newcomer needs also more complex examples, like tutorials or cookbooks. Use only one link in documentation to avoid clutter.
5	opinionated suggestions in getting started https://wiki.dlang.org/Getting_Started	a newcomer is overwhelmed by the possibilities of compilers,editors/ides; Suggestions: dmd, vscodium with code-d
6	pack this task list somewhere on the wiki	done
7	encourage newcomers to edit the wiki	This is a simple task, often dull to do for experienced community members, but great for newcomers, because they are included AND they explore the wiki and the community on themselves.
8	Finish the book https://github.com/PhilippeSigaud/D-templates-tutorial
9	declare unmaintained and broken packages as such
10	document -preview, make a timeline for those changes, document them e.g. per switch in a github issue (like bazel does)
11	better docs for simd. How do I add new opcodes, if I miss one? Tutorials.
12	better docs for dub, subpackages, examples, recommended project layouts
13	better docs/tutorials for the mir libraries
