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

## About drop-in plugins

Drop-in plugins, such as ```Hyperdb```, do not have to be installed in the plugins directory, but we have instead to place files directly into wp-content.
We have to thus manually specify where they have to go.
