 # This is an example. Please change the configuration variables listed here.
+#
+# This example uses a volume to persist the sqlite database outside of the container,
+# please adapt the local path.  If you use a custom PUID and PGID, you need to create
+# the local path beforehand with the correct user/group.
+#
+# You can generate an admin password with: docker run -it --rm --entrypoint ihatemoney ihatemoney/ihatemoney:latest generate_password_hash
+# IMPORTANT: replace every dollar character in the result with a double dollar ($ -> $$)
+# To disable admin access, simply set the password to an empty string (ADMIN_PASSWORD=)
+#
+# See https://ihatemoney.readthedocs.io/en/latest/configuration.html to understand all settings.
