**Reason**
[[https://www.mediawiki.org/wiki/Extension:GettingStarted|GettingStarted]] was originally written to support new Wikipedia users; it has been superseded at that task by [[https://www.mediawiki.org/wiki/Extension:GrowthExperiments|GrowthExperiments]] and has recently been undeployed from Wikimedia (T235752). There's a cost to any extension, especially complex ones, as they make refactoring MediaWiki core (something that's been happening a lot lately) slower, so if no one needs it, we should archive the extension.
For now this task is just to gather feedback from affected wikis. (WikiApiary lists [[https://bit.ly/3izJGW0|10 such wikis]], but per T292651 it doesn't seem reliable.)
**To-do list**
- This task
-- [x] Add maintainers of that extension/skin as subscribers to this task (if they have no apparent Phabricator account, notify them on-wiki or via email if possible and note it here).
-- [x] Add Phabricator project <#ProjectX> as a tag for this task, and remove #mediawiki-extensions-other/#other-skins as appropriate.
- On-wiki documentation
-- [x] Archive documentation on `mediawiki.org` (provide URL): replace page contents with `{{Archived extension|last revision id before archiving|task=T######}}` (for extensions); replace `T######` with this task's number.
-- [x] If documentation page was translatable, remove `<translate>`, visit Special:PageTranslation, and click "remove from translation" (if you don't have the translation administrator right, ask a [[ https://www.mediawiki.org/wiki/Special:ListUsers/translationadmin | user who does ]]).
-- [x] Update Wikidata item (provide URL) associated with documentation page
--- [x] add statement `Abandonware (Q281039)` to `instance of (P31)` together with qualifier `start time (P580)` = the YYYY-MM-DD date that you decided to archive extension/skin (generally per edit history)
--- [x] add qualifier `end time (P582)` = the YYYY-MM-DD (same date as above) to `instance of (P31) = MediaWiki extension (Q6805426)/MediaWiki skin (Q21996535)`
- Phabricator
-- [x] Mark [all Phabricator tasks for the extension](https://phabricator.wikimedia.org/maniphest/?ids=306488,258568,163943,158239,92147,92075,92057,78213,73452,70550,67795,53634,53076,92178,92175,92167,92160,92149,92134,92131,92130,92129,92127,92124,92090,92088,92084,92073,73253,72741,72645,71925,71922,67551,65173,65172,65147,62521,62325,59943,54246,53466,53425,51995) either Declined or Invalid. Add a comment pointing to this task when doing so for reference.
-- [x] Archive Phabricator project <#ProjectX> for the extension/skin.
-- [x] Edit Phabricator project <#ProjectX> description for the extension/skin with a link to this ticket.
- Translatewiki.net/translations
-- [ ] Remove from `translatewiki.net` ([[ https://gerrit.wikimedia.org/r/plugins/gitiles/translatewiki/+/refs/heads/master/groups/MediaWiki/mediawiki-extensions.txt | groups/MediaWiki/mediawiki-extensions.txt ]]
- Configuration/tests/integrations/etc.
-- [x] Remove tests in [[ https://gerrit.wikimedia.org/g/integration/config | integration/config ]] ([[ https://gerrit.wikimedia.org/r/plugins/gitiles/integration/config/+/master/zuul/layout.yaml | zuul/layout.yaml ]]).
-- [ ] Remove manifest/other references from [[ https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/vagrant/+/master | mediawiki/vagrant ]] if they exist.
-- [x] Remove from https://doc.wikimedia.org/cover-extensions/ if present (requires #continuous-integration-infrastructure shell user to delete directly from the server).
- Repositories
-- [x] Empty repository, leaving only the README indicating the repo is archived, and referring to this task by URL.
-- [ ] Remove from [[ https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/+/master | mediawiki/extensions ]] (along with in `.gitmodules`).
-- [x] Mark the repository read-only in Gerrit (also edit description to prepend "[ARCHIVED]" and a reference to this task): https://gerrit.wikimedia.org/r/admin/repos/mediawiki%2Fextensions%2FGettingStarted,general
-- [x] Deactivate the Diffusion repository for the extension/skin: https://phabricator.wikimedia.org/diffusion/EGST/
-- [x] Delete the GitHub mirror: https://github.com/wikimedia/mediawiki-extensions-GettingStarted
