+The `metadata.db` holds the library and `app.db` and `gdrive.db` contain the
+web/account information.
+
+Place books directories in `/data/books/`.
+
+Place `metadata.db` in `/var/lib/calibre-web-db/`.
+
+Symlink `metadata.db` to the library:
+
+```
+sudo ln -s /var/lib/calibre-web-db/metadata.db /data/books/metadata.db
+```
+
+Place `app.db` and `gdrive.db` in `/var/lib/calibre-web/`.
