One of the conclusions of DrupalCon Baltimore was that Drupal 8 has impressive tools to build a decoupled application. However, assembling all the tools together and setting them up correctly can be a little bit daunting. On top of that, once you have everything set up you need to figure out the ins and outs of your front-end project.
With this in mind, Contenta CMS is born to make your content happy. Contenta CMS is the response of the community to build an API-First Drupal distribution. The goals of Contenta are simple: provide a standard platform that is API ready along with demo content and example front-end applications. In summary, Contenta intends to ease the pain of using, or simply trying, decoupled Drupal.
