Maybe we should just link to the wiki pages and update the info there?

Makes sense. I'll update the pr this noon.
I'll also fix the entry in the wiki, because there is the same wrong text as well.

André (@serious6) I'll updated the readme to the link.

There are some duplicate informations on the wiki.
For example the maven/gradle part can be either found here:
https://github.com/OfficeDev/ews-java-api/wiki#maven--gradle-integration
or here:
https://github.com/OfficeDev/ews-java-api/wiki/Getting-Started-Guide#maven--gradle-integration

Shouldnt we delete informations on the first page? So we dont need to update two pages.

Thanks for pointing this out. The information should be centralized while updating the remaining references. Maybe the sections on the readme should also be more generalized/combined while pointing to the wiki pages.

Manuel (@WtfJoke) thanks for your contribution
