I'm totally fine with mw:Writing_an_extension_for_deployment over mw:Review_queue. "Review queue" isn't immediately obvious what it's for and people won't find it easily on their own (is my guess); they'll find the former.

So yeah, merging them would be great. Adding good first bug .

...to be explicit: after merge we can probably just redirect "Review queue" to "Writing and extension..."

@greg @Aklapper
I want to solve this issue.
Can you provide some guidance how can I do this as this is my first task?

@Mayank.jindal5: Thanks for your interest and help!
See https://en.wikipedia.org/wiki/Wikipedia:Merging#How_to_merge basically, making sure that no information is duplicated anymore and no important information is missing after merging into one page.
It's probably best if you draft the merged version on a wiki page which is a subpage of your personal user page on mediawiki.org. After it's fine its content could be copied into the current "real" page.
If you have any specific questions feel free to ask - happy to help! :)

@Mayank.jindal5: Just checking: Anything we can help with? (Do you still plan to work on this?)

• Writing_an_extension_for_deployment suffers from trying to cover very different things on one page: There's the generic "writing an extension" properly part but there are also aspects related to "for deployment on WMF sites". The first is clearly https://www.mediawiki.org/wiki/Manual:Developing_extensions and should not be on the Writing_an_extension_for_deployment page.
• The "Checklist/Process" order on "Review queue" is different from the order of items on the "Writing an extension" page and its "Set up your new project" section.
• "Checklist/Process" on "Review queue" has items like "Product review, if applicable" and "Design review, if applicable" but does not explain criteria to judge when it is applicable, and does not explain what a "product review" is.
• The "Tips" section on "Review queue" does not tell you when to perform these steps.

@Xephyr826 Welcome.
You can work on this task.

@Xephyr826: Thanks a lot!

The more I think about this task, the more I think this is not an good first bug task, as I don't think that our docs match reality - if we asked for community support first and only after that ask to start to write code I can imagine that the community opinion would be asked for again once the code is close to being 'ready for deployment'.

What should likely be doable to contribute here though is splitting out the generic parts "how to write an extension" (not necessarily for deployment) and making sure relevant parts are covered in https://www.mediawiki.org/wiki/Manual:Developing_extensions .

@Xephyr826: Sorry that I'm probably a bit demotivating - not my intention but it seems to be more complex than expected to 'do this right'. :-/

@Aklapper , No problem. I can take a shot at splitting out the "how to write an extension" parts.

By the way, I wanted to mention that I watched your Wikimania talk on phabricator and it helped motivate me to try to contribute.

Alright, I'm done with mw:Review queue and nothing is left on mw:Writing an extension for deployment not covered in mw:Review queue.
I tried to split "general prerequisites" and the actual deployment process. And I admit I added some stuff too. Like mentioning a DBA review.

@greg: mw:Review queue now welcomes a review as I copied some info that might be outdated (who knows, I don't deploy).

Remaining questions:

• What the heck is a "product review"?
• Do we still have performance/scalability reviews?

Going to set up the page redirect now and then my work here is done. Word.
