+## Subresource Integrity for Javascript resources
+
+Because we implemented [Subresource Integrity (SRI)](https://www.w3.org/TR/SRI/) the SRI hashes in the templates need to be regenerated after each change of a javascript file. To make this easy, we implemented a mechanism for this into the unit testing bootstrap process. After changing any javascript file, follow this process:
+* edit the javascript file(s)
+* run the unit tests as described above
+* deploy the updated javascript file(s) _and_ the updated templates on your webserver
