-- Using external storage is slower than necessary because NextCloud request objects metadata separately during the same HTTP request. This can be improved by caching the results at the initial list operation. 
-- Under unknown circumstances a segfault seems to occur.
+- Enabling Xdebug profiling or debugging will cause a segfault

+
+## Configuration
+
+Storj works like any external object storage. See the documentation on docs.nextcloud.com:
+
+* [Configuring External Storage (GUI)](https://docs.nextcloud.com/server/22/admin_manual/configuration_files/external_storage_configuration_gui.html)
+* [Configuring Object Storage as Primary Storage](https://docs.nextcloud.com/server/20/admin_manual/configuration_files/primary_storage.html)
+
+This is the configuration to set Storj as your primary storage:
+
+```php
+$CONFIG = [
+    'objectstore' => [
+        'class' => \OCA\Storj\StorjObjectStore::class,
+        'arguments' => [
+            'serialized_access' => 'myaccessgrant',
+            'bucket' => 'mynextcloudbucket',
+        ]
+    ]
+];
+```
