+### Creating fixtures for local testing
+
+**Backing up**
+To create a fixture to share content with another person you should do the following:
+
+```shell
+python manage.py dumpdata --natural-foreign --indent 2 \
+   -e contenttypes -e auth.permission \
+   -e wagtailcore.groupcollectionpermission \
+   -e wagtailcore.grouppagepermission \
+   -e wagtailimages.rendition \
+   -e sessions \
+   -e admin \
+   -e wagtailsearch.indexentry \
+   -e accounts.userprofile \
+   -o fixtures/data.json
+```
+Then make an archive/zip of your `media/` and `fixtures/` directories. This is because
+the image files need to be copied alongside the data. If needed, you may want to delete
+some images first before sharing.
+
+**Restoring**
+
+1. Make a backup of your current media directory. This is so you can revert later
+on.
+2. Unpack the archived file, and place the `media/` and `fixtures/` directories at the
+top level of the project.
+3. Create a new database such as ``createdb -U djangonaut -W -O djangonaut djangonaut-space2``
+4. Change your settings or environment variables to point to the new database
+5. ``python manage.py migrate``
+6. ``python manage.py loaddata fixtures/data.json``
