+# Postprocessing service
+
+The `postprocessing` service handles coordination of asynchronous postprocessing. 
+
+## Postprocessing functionality
+
+The storageprovider service (`storage-users`) can be configured to do asynchronous postprocessing by setting the `STORAGE_USERS_OCIS_ASYNC_UPLOADS` envvar to true.
+If this is the case, the storageprovider will initiate an asynchronous postprocessing after he has reveived all bytes of an upload. The `postprocessing` service will then 
+coordinate various postprocessing steps (like e.g. scan the file for viruses). During postprocessing the file will be in a `processing` state during which only limited actions are available.
+
+## Prerequisites for using `postprocessing` service
+
+In the storageprovider (`storage-users`) set `STORAGE_USERS_OCIS_ASYNC_UPLOADS` envvar to `true`. Configuring any postprocessing step will require an additional service to be enabled and configured.
+For example to use `virusscan` step one needs to have an enabled and configured `antivirus` service. 
+
+All of this functionality will need an event system to be configured for all services: `ocis` ships with
+`nats` enabled by default.
+
+## Postprocessing steps
+
+As of now ocis allows two different postprocessing steps to be enabled via envvar
+
+### Virus scanning
+
+Can be set via envvar `POSTPROCESSING_VIRUSSCAN`. This means that each upload is virus scanned during postprocessing. `antivirus` service is needed for this to work.
+
+### Delay
+
+Can be set via envvar `POSTPROCESSING_DELAY`. This step will just sleep for the configured amount of time. Intended for testing postprocessing functionality. NOT RECOMMENDED on productive systems.
