Hi all, I'd like to share a new way to set up a local development environment for MediaWiki: Local development quickstart.
The purpose of the quickstart guide is to provide the shortest, simplest path to running MediaWiki locally for people who don't want to use Docker. The goal is to eventually replace the Local installation section on How to become a MediaWiki hacker with a link to the quickstart guide. For more background information, see T347347 on Phabricator.
If you're interested in helping test the quickstart guide, please share your feedback on the talk page or on the Phabricator task. For feedback about MediaWiki development environments in general, I've started a comparison of available options and key pages on Project:Development environments.
