+# testdata
+
+## Database content
+testdata is provided in this repository / directory in testdata.json. It has been
+dumped using: 
+
+```
+manage.py dumpdata --all --exclude=auth --indent 4 --o testdata/testdata.json
+```
+
+You can import it using 
+
+```
+manage.py loaddata testdata.json
+```
+
+## Images
+Although I created pretty small testimages, I think they are still too clunky to
+mindlessly dump it into the code repository, so I provide an 
+[archive](https://www.commander1024.de/lostplaces-testdata.zip) containing
+a folder structure of images to be extracted into the uploads/ folder.
