A thing to note here is my IDE does not translate the GitBook syntax like {% code title="PreventRedirectCreationHandler.cs" %} - I tried following the pattern established in other files, but please correct me if it's wrong.

The Link checker fails on this, because the build has not been released yet, therefore the links do not exist yet. It should however be correct, will have to double check when we release this
