To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While we are doing this to improve our development experience in the short term, efforts are also in place to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted back out in the future when components is ready to leverage it as well.
