README.md

+This is an attempt to re-structure the ai/noblogs-wp> repository using Composer.
+
+Some rough ideas on how the situation could be improved:
+
+- the ```upstream``` branch should disappear. We should not have to care ourselves on keeping a sync of Wordpress source code
+- we should really just keep the patches and our contributions
+- we need to be able to build a docker container in the end
