Patch demo
PatchDemo is a rather interesting Wikimedia project. It allows users to spin up temporary MediaWiki instances from version 1.23 to the beta 1.39 builds and apply any patches they want. It's also a good way to test out MediaWiki without vandalism complaints or being blocked. Users will also need a Wikimedia account, which can be done easily.
== How to create a wiki ==
It's very simple.
* 2) Sign in with your Wikimedia account.
* 3) Select a MediaWiki version, master is the default (and loads the newest 1.39 build), You can also select 1.38 if that's your gig.
* 4) You can add any patches from Gerrit if you want.
* 5) Fill out the rest.
* 6) Click "Create demo"!, the website will automatically install MediaWiki for you and set up the database. You will receive a browser notification (if you enabled them) when your wiki is created.
== Closing a wiki ==
Just like creating a wiki, closing it is simple.
* 1) Go back to the website.
* 2) Under "My wikis", click Delete under the wiki you want to close.
* 3) Confirm the deletion
* 4) Done!
