(This is intentionally about a proposal workflow only, and intentionally independent from the actual technology or infrastructure used.)
- Create a dedicated Phabricator project tag for content changes on the future Developer Portal.
- Offer a Phab task template or task form, to have structured tasks with (hopefully) all wanted information initially available.
- Document this workflow, for example on a dedicated subpage of https://www.mediawiki.org/wiki/Developer_Advocacy/Developer_Portal (or such).
- Allow discoverability of that workflow documentation by having a link on the developer portal site itself (e.g. in footer).
