+Frequently asked questions
+**************************
+
+**Q:** *I'm using docker. Where are my documents?*
+
+**A:** Your documents are stored inside the docker volume ``paperless_media``.
+Docker manages this volume automatically for you. It is a persistent storage
+and will persist as long as you don't explicitly delete it. The actual location
+depends on your host operating system. On Linux, chances are high that this location
+is
+
+.. code::
+
+    /var/lib/docker/volumes/paperless_media/_data
+
+.. caution::
+
+    Dont mess with this folder. Don't change permissions and don't move
+    files around manually. This folder is meant to be entirely managed by docker
+    and paperless.
