Looks good @haithamshahin333. I noticed that the container topic area doesn't have a README.md file. Should it?

Thanks @timothymeyers for reviewing! When the repo was setup we put the README's in the empty folders really as placeholders so that the folder structure would exist (since the empty folders otherwise could not be committed).

I went ahead and removed for the Containers folder as well as Container/Solutions since now that there is content there, that placeholder shouldn't be needed, and this way when we're adding content we can add just to one README on our main page.

A good callout though that as we add content to currently empty folders, we should remove the placeholders to avoid confusion.
