Some themes like for example [Hyde Hyde](https://github.com/htr3n/hyde-hyde/tree/master/exampleSite/content) have their content files under a section called `posts`
Currently the index page of these theme demos renders empty because there is no `posts` section in the HugoBasicExample.
So to fix this I have added a symlink called `posts` that points to the content files located under the `post` of the HugoBasicExample repo.
In theory this workaround can be used for other sections as well like e.g. `articles` etc (as long as it doesn't break anything).
