+<a id="Store-Config"></a>Store your Configuration
+=====================================================
+
+Changes to your *Business Process Configuration* are added to a stack and will
+not be stored immediately. In case there are pending unstored changes, this will
+be shown on every screen:
+
+![Pending Changes](screenshot/21_store-config/2101_Pending-Changes.png)
+
+A click on *Dismiss* immediately throws away all unstored changes. A click on
+*Store* brings you to the configuration form. You have seen this before, once
+you created your [very first configuration](02-Getting-Started.md):

+
+Config Diff
+-----------
+
+If unsure what changes you're going to store, you can still check the *Config Diff*
+before finally storing to disk:
+
+![Show Diff](screenshot/21_store-config/2103_Show-Diff.png)
+
+You can also download your existing configuration to safe it elsewhere or to
+apply manual modifications with our favourite plaintext editor.
