I would add, if I may...
If you're going to implement a wiki for documentation (and / or) things like a development methodology and / or coding standards - get the "whole" development team to create them on a wiki, too.
I always go with "the majority wins" - unless I just happen to know that "X" sounds great but never works; then I will make a "captain's decision" and say "No". - but also make sure I explain why...
The beauty of doing ALL rules - in a wiki - is that they can be changed, easily.
The REAL beauty of getting the development team to write their own - is that "they" own the rules.
They weren't "just" forced upon them.
So they automatically "buy-in" to the agreed standards. Even when they personally agree to a rule or two.
Also make sure that any code reviews / PRs follow the same documentation and you MUST not allow any code that doesn't match the standard to "stay" in your code base.
"Oh the coding standards say 'tabs of 4 spaces' / 'IFS / LOOPS / ETC start on a new line with a blank line above and below... Or the agreed standard states we will ALWAYS use a service and gateway class - unless it is a report: and then it MUST use the reporting engine.... All emails MUST be sent via the emailService... / etc...
and this code we're currently looking at: doesn't follow those rules - you'll need to redo it to match the "standard".
This ALSO works - even for a single developer.
It has stopped me from my own stupidity at times.
My ultimate goal in all this isn't you follow my rules or there will be hel;l to pay - it is;
Everyone writes the same code, the same way.
So it doesn't matter that "Bob" wrote it - when "I" come to read it / update it / debug it - it reads to me - like I had written it myself.
Sorry got a bit off - topic! :D
