Please take a look at our C2 Matrix Eval Lab so that testing can be performed in a consistent manner. The easiest way to contribute is to copy the row you want to update from the Google Sheet Golden Source and share it with us via Twitter or Feedback form.
You can also let us know if there is a particular field that is not accurate such as "Baby Shark row 5 states implementation is by pip3 but it is really install.sh" (this is just an example). We do prefer the entire row filled out.
Thank you for your interest in contributing and giving back to the community. As a token of appreciation we will make every effort to credit your work. Anyone that does a full C2 evaluation will have Twitter handle added to "Evaluator" column and receive many shout outs and thank yous on Twitter. We appreciate all that you all do for the community!
