+Unit Tests
+----------
+
+Tests are currently not running on Travis CI as they require
+docker container configuration that is still on the todo list. We
+will provide a testing guide once everything is up and running.
+
+Dependencies
+------------
+We are using [dep](https://github.com/golang/dep) for dependency management:
+
+```
+dep ensure
+go test
+```
+
+In addition, PhotoPrism requires [darktable](https://www.darktable.org/) to convert RAW images to JPEG.
+We are working on a docker container that contains it so that you don't have to install it locally.
