+Scaleway
+=============
+
+Scaleway Object storage implements the S3 protocol. To use it follow the instructions in the :doc:`Amazon S3 docs <amazon-S3>` with the important caveats that you must:
+
+- Set ``AWS_BUCKET_NAME`` to the Bucket you want write to (such as ``my-chosen-bucket``)
+- Set ``AWS_S3_REGION_NAME`` to your Scaleway region (such as ``nl-ams`` or ``fr-par``)
+- Set ``AWS_S3_ENDPOINT_URL`` to the value of ``https://s3.${AWS_S3_REGION_NAME}.scw.cloud``
+- Set ``AWS_ACCESS_KEY_ID`` to the value of your Access Key ID (i.e. ``SCW3XXXXXXXXXXXXXXXX``)
+- Set ``AWS_SECRET_ACCESS_KEY`` to the value of your Secret Key (i.e. ``abcdef10-ab12-cd34-ef56-acbdef123456``)
+
+With the settings above in place, with django storages set as DEFAULT_FILE_STORAGE, if you wrote a file like so:
+
+
+    from django.core.files.storage import default_storage
+    file = default_storage.open("my_chosen_file.txt", "w")
+    file.write("storage contents")
+    file.close()
+
+If would be written to the following address:
+
+https://s3.nl-ams.scw.cloud/my-chosen-bucket/my_chosen_file.txt
