+==== For using S3 or an alterantive service ====
+You need the ''boto3'' and ''django-storages'' packages.
+An example of settings would be...
+<code>
+AWS_ACCESS_KEY_ID = ''
+AWS_SECRET_ACCESS_KEY = ''
+AWS_STORAGE_BUCKET_NAME = 'codi.coop.test'
+AWS_S3_CUSTOM_DOMAIN = f's3.wasabisys.com/{AWS_STORAGE_BUCKET_NAME}'
+AWS_S3_ENDPOINT_URL = 'https://s3.wasabisys.com'
+AWS_DEFAULT_ACL = 'public-read'
+DEFAULT_FILE_STORAGE = 'cc_lib.storages.MediaStorage'
+EXTERNAL_MEDIA_PATH = 'fok/media'
+MEDIA_FILE_OVERWRITE = True
+# AWS_S3_OBJECT_PARAMETERS = {'CacheControl': 'max-age=86400',}
+</code>
+Being the ''cc_lib.storages.MediaStorage'' the next:
+<code python>
+from storages.backends.s3boto3 import S3Boto3Storage
+from django.conf import settings
+class MediaStorage(S3Boto3Storage):
+    location = settings.EXTERNAL_MEDIA_PATH
+    file_overwrite = settings.MEDIA_FILE_OVERWRITE
+</code>
+With this you could create other storages like ''PrivateMediaStorage'' and use it like this:
+<code python>
+class Document(models.Model):
+    uploaded_at = models.DateTimeField(auto_now_add=True)
+    upload = models.FileField()
+class PrivateDocument(models.Model):
+    uploaded_at = models.DateTimeField(auto_now_add=True)
+    upload = models.FileField(storage=PrivateMediaStorage())
+    user = models.ForeignKey(User, related_name='documents')
+</code>
+==== So... ====
+  - Install boto3 and django-storages.
+  - Create your own MediaStorage.
+  - Add the settings.
+  - Configure models.
+  - Remind that forms in template must have the attribute ''enctype=“multipart/form-data”''.
+==== Notes ====
+<code python>
+def upload_path(instance, filename):
+    if instance.type == Resource.ResourceType.PROFILE_PICTURE.value:
+        return f'authors/{instance.owner.uuid}/avatars/{instance.uuid}.png'
+    elif instance.type == Resource.ResourceType.ZINE_COVER.value:
+        return f'zines/{str(instance.related_to)}/cover.jpg'
+</code>
