contradiction in "Rights to your contributions"

[Nikita Koselev, Open Source DevRel]

These 2 points contradict each other.
1st states that you must have authored 100% and 2nd explain that it's not necessary to author 100%.
I suggest this case is raised as a good first-time issue for some friendly technical writer to fix.

Agree that you have authored 100% of the content
...
Agree that, if you did not author 100% of the content, the appropriate licenses and copyrights have been added along with any other necessary attribution.

Ah, true. Looks like the original contributing file hasn't been changed since @Avanade first donated the code.

I've updated it in Avanade's contributing file, but good flag for this project.

Thank you @nikitakoselev - have updated this in the dev branch to remove the contradiction.
