Currently looking at how I can help with the official WordPress documentation from (https://make.wordpress.org/) here. But I am confused about how it gets documented on who did what.
May I suggest trying a much smaller project? Wordpress probably has a well established documentation team and standard. You won’t be making a name for yourself there unless you do something really amazing.
There are many small open source projects that could use a technical writer’s help.
Not trying to be a jerk, but I have an alternate thought. OP could find a specific area of the Wordpress documentation that needs improvement, make that improvement, and do a pull request or whatever. That would probably be a good way to get the team’s attention.
