A bit of an overlap (duplication) in documentation caused by linking to an external resource

The front page of https://www.gitbook.com/book/adoptopenjdk/adoptopenjdk-getting-started-kit/details points to [Click here for Quick Start Guide](https://mikebgx.gitbooks.io/adopt-openjdk-quickstart-chapter/content/quick-start.html) which is essentially already present in the existing guide, and there are no/or fewer backlinks to the main guide.

Readers might get lost in the navigation process, but its best to maintain on source rather than multiple pathways.

Look for sub-pages under https://adoptopenjdk.gitbooks.io/adoptopenjdk-getting-started-kit/content/en/ and in the Quick Start Guide and merge them wherever they overlap or fill the gaps. Which also means changing the English version means other pages of other languages will need an update as well.

Best person to chat with is @mikebgx for any questions about the Quick Start Guide.
