User:APaskulin (WMF)/Sandbox/Development guidelines

The MediaWiki software is developed collaboratively by people from all around the world. To help facilitate this process, standards of desirable practices have been established.


Development policies describe what developers must do. There can be no deviations from policies.

Code review rights and responsibilities for MediaWiki core and components

Unlike policies that describe what developers must do, development guidelines describe what developers generally should do. Minor deviations from guidelines, like coding conventions, can often be allowed based on individual circumstances. Whether there is good reason for a given deviation that is worth the downsides of conformity to the established norms is a matter for judgment of developers and their code reviewers.
