+Command-line uploading
+======================
+
+Want to submit media via the command line?  It's fairly easy to do::
+
+  ./bin/gmg addmedia username your_media.jpg
+
+This will submit the file "your_media.jpg" to be a media entry
+associated with the user "username".
+
+You can get help on all the available options by running::
+
+  ./bin/gmg addmedia --help
+
+Here's a longer example that makes use of more options::
+
+  ./bin/gmg addmedia aveyah awesome_spaceship.png \
+      --title "My awesome spaceship" \
+      --description "Flying my awesome spaceship, since I'm an awesome pilot" \
+      --license "http://creativecommons.org/licenses/by-sa/3.0/" \
+      --tags "spaceships, pilots, awesome" \
+      --slug "awesome-spaceship"
+
+You can also pass in the `--celery` option if you would prefer that
+your media be passed over to celery to be processed rather than be
+processed immediately.
