Whoops integrates the whoops library into MediaWiki, in order to show nice stack traces on errors.

Download and move the extracted Whoops folder to your extensions/ directory.
Developers and code contributors should install the extension from Git instead, using:
```
cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Whoops
```
Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See T173141 for potential complications.)
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'Whoops' );
```
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
