Page has been updated but could use more useful content. Leaving open.

https://wikitech.wikimedia.org/wiki/Help:Toolforge/How_to already lists tutorials per programming language. This mostly duplicates the "Developing tools" section in https://wikitech.wikimedia.org/wiki/Template:Toolforge_nav (which e.g. lacks Django or a link to https://wikitech.wikimedia.org/wiki/Help:Toolforge/Rust or Node.js ).

See also T245454: Create guidelines and template for Toolforge help pages that provide information about developing in different programming languages.

IMHO the page https://wikitech.wikimedia.org/wiki/Help:Toolforge/How_to should NOT exist and be removed: Unclear scope (and confusing page name).

Currently working on implementing subcategories to provide navigation to tutorials and how-to docs by language using page metadata instead of a manually-maintained page: https://wikitech.wikimedia.org/wiki/Category:Tutorials

After I create and apply categories for the different programming languages, I'll be able to deprecate https://wikitech.wikimedia.org/wiki/Help:Toolforge/How_to. The revised Toolforge nav template will provide direct links to tutorials for the most popular programming languages (as evidenced by 2022 Cloud Services User Survey responses), and will link to the Tutorials category page as a full listing (I'll go back in later and clean up the sort keys so the pages sort by the programming language instead of page title).

Created and applied category metadata to pages for:
https://wikitech.wikimedia.org/wiki/Category:Programming_languages
and
https://wikitech.wikimedia.org/wiki/Category:How-to-guide.

Next and final step is to figure out the best way to direct readers to the intersection of Toolforge category + these categories, or if that's even necessary since right now and likely for the foreseeable future, the only docs with these categories are Toolforge docs.
