+When building your project specific CKAN images (the ones defined in the `ckan/` folder), you can apply patches
 to CKAN core or any of the built extensions. To do so create a folder inside `ckan/patches` with the name of the
 package to patch (ie `ckan` or `ckanext-??`). Inside you can place patch files that will be applied when building
 the images. The patches will be applied in alphabetical order, so you can prefix them sequentially if necessary.

+The images use the application server [_uWSGI_](https://uwsgi-docs.readthedocs.io/en/latest/) to run _CKAN_.
