+# Volumes/IGNORED/README.md
+
+Docker volumes which do not need included in backups and are safe to delete
+during downtime without harming the integrity of the application they support
+can be directed here.
+
+Examples could be:
+
+- LibreTranslate's models
+    - These can be downloaded at any time and do not need recovered.
+- Provision Tests
+    - These are test VMs which ensure privisionin scrips work proeprly.
+    They are meant to be disposed of frequently and recrated from scratch.
+
+If working on test VMs, such as a dev or stage Nextcloud that shouldn't be
+taking up backup space, this would also be a good place for them.
